In Praise of Wadding…

Without wadding, there would be no salt firing.  I believe that most atmospheric firers wad their pots to some degree, and I know that there is great variation in how wadding is made among potters.  For those of you who have not taken part in salt firing of pottery or other atmospheric firing, the vaporous kiss of the salt (or wood ash, or soda….) is what creates the special effects we seek on the surface of our work.  That same vaporous kiss will fuse your pot right to the shelf upon which it sits, where it may shatter into dangerous shards as the kiln cools and it cannot shrink at the same rate as the shelf.  What to do?

Each piece that goes into the kiln must perch upon balls of wadding.  This wadding leaves small white circles where it has been adhered to the pot.  Many buyers hate these white dots, and want pots that don’t have them. They are particularly incensed by the wad marks – usually long ovals – that remain from where wads are placed when casserole lids are fired in place.  Sigh…  Here are some typical wad marks on a salt pig from my recent load.

Salt Pig 1 Bottom

I have used a lot of different combinations of materials to make my wadding.  At this time, I use a 50-50 mixture of alumina hydrate and Helmar kaolin BY VOLUME.  Wearing my respirator, I measure the materials out into a plastic dishpan.  I use about 8 cups of each material, which makes about 10 pounds of wadding.  I mix the two materials by hand, and then add water.  It’s okay to make it too sloppy; just add more of each until you get it right.

I like to make wadding one batch ahead during a firing.  That way, it has time to become more plastic and easier to roll out into coils.   I often mix up the wadding, and then cover it with plastic for a few days before wedging.  I prefer to wedge it on the formica top of my slab roller table rather than on my plaster wedging table.  The alumina hydrate makes it into un-clay, and it sticks to the plaster in an untidy way, even as it is being blended.

When it is smooth and uniform, and still a bit wetter than I would like when I make my wads, I pack it into a tightly covered plastic container from the restaurant supply store and put it in my storage area.  It’s good to keep it on the wet side, because unlike clay, I can’t seem to rehydrate it by spritzing or sprinkling water into it.  Other wads have been easy to rehydrate, but this wad has specific properties that are more important.

What are the properties a salt-firer requires from wadding?  First, and most important, is how the wadding comes free from the pot after firing.  The first wads I used required much hand sanding to make the places where wads had been adhered smooth and attractive.  This quickly becomes wearisome!  I have been known to describe myself a a connoisseur of abrasives, and this is sadly true.  Shelves must be sanded after each firing, kiln posts too; you have to be a little bit nuts to do all this work when you could snatch soulless but serviceable cone 6 pots out of an electric kiln with none of these annoyances…

My first hands-on experience with salt firing was as observer of Craig Martell’s salt-firing process.  Craig has a big salt kiln that he fires occasionally, and agreed to let me come when he was setting up to fire, and even put some of my first pots for salt in his kiln.  I helped with wadding, and learned that a person has to stick the wads on with Elmer’s. Craig has vast technical knowledge, and without his help, I would have given up on learning to salt fire and returned to red earthenware, most likely.  Here’s a pot of mine from that firing in Craig’s kiln. I have never been able to duplicate some of the effects on this humble piece – I still use this gold slip, but it hasn’t been willing do this in any of my three salt kilns….

Pot from CRaigs Kiln

The first wadding I made myself incorporated flour along with alumina hydrate and EPK kaolin.  It was okay to roll out, made decent balls/spheres/bollitos of wadding.  It also soured quickly and needed to be used with a day or two.  I used to put the leftover bits of wadding into the freezer, and still find a small,  mysterious bag of frozen dough once in a while.

James Tingey, another fine Oregon potter, came up and fired with me once,  and introduced me to wadding made with wood sawdust.  This took less sanding, but made a larger minimum wad which didn’t work for my small pieces such as butter boxes.  I am not sure at what point I switched to my present mix, but it’s clearly the best for ease of forming and removal, and keeps forever.  It becomes much more plastic as time goes on, too.

There are two principle uses for wadding in the kiln; setting up the pots, and wadding the furniture.  I may also use wadding for chinking in the kiln, especially since I am laying up a brick door again.  It shrinks, and probably doesn’t really stop that much flame, but it makes me feel like I am doing something.  Better to stuff shreds of kaowool in; but I worry about fibers.  I should research this hazard…

I like to make all the wads for the firing before I start stick them on, and have become surprising good at guessing how many will be needed.  I need two full plates of 1/2″ balls for general use, about 100 3/4″ balls for wadding the contact point between my silicon carbide barstock and the shelves, and about 32 big fat wads of wad for the tops of the posts I use top separate the shelves – 4 per shelf.  Here’s a plate of small wads ready for wadding pot bottoms and lids as well.  I fill up rectangular plastic plates, which are tucked into ziplock bags.

Waddimg

Potter friends contact me from time to time to tell me about new ways to make wads.  A potter somewhere rolls wadding into a small slab, then presses a straightedge into the slab at intervals, in two directions, to create small regular cubes connected at the base,  It’s bisqued, snapped apart, and glued onto pots.  Is this easier than what I do?  Maybe…

How does a potter learn this stuff?  I have been extraordinarily well mentored, not only by Craig, but also by longtime friend and ceramic engineer Barrett Jackson, who regularly introduces me to all sorts of high tech materials.  From him, I got boxes of ceramic cam rollers – diesel engine parts – rejected products of a high-tech manufacturing firm where he worked for years.  These make the all-time best ever kiln posts for salt.  From him I also got – free, for picking it up in LA – my barstock that I use to set the load.  Here’s a shot of early stages of stack building.

Starting the StackYou can’t see the 3/4″ wads under the shelves, but they are there.  And you can see the big wads on top of the kiln posts, waiting for the next pieces of barstock to be laid over the top of them.  You also can’t see the level that I keep at hand.  I check level on the shelves in both directions – at this point, I rarely need to make an adjustment.  All that wadding helps to keep things level…

I wad all pots that go into the kiln, but I don’t wad salt and pepper shakers, beads, tiny cruet lids, and suchlike.  Because my shelves are carefully cleaned after every firing, this works for me.  I’ve considered experimenting with un-wadded pots, but the potential for variation in vapor movement in the kiln makes me feel safer firing with wads.

So!  If you have gotten this far, thank you…  This is pretty dull stuff, Unless you want to fire a salt kiln.  It’s the only way I know to get effects like this….

Making a new lid for my old butter boxes…

Finish BB House Here’s  is a favorite butter box, slightly grimy from sitting around my studio with other pieces I like too much to sell.  I do like to make boxes.  Hand-building is is a guilty pleasure for an impatient person like me who sometimes doesn’t love the many steps of wheel thrown pottery in my process.   Thinking about it now, I realize that it’s probably just as complex if you take righteously prepping the clay into account.

I am very particular about readying my slabs for hand building.  I do have a nice slab roller, which speeds the process and yields up perfect slabs of various thicknesses.  For the butter boxes, an extruder prepares the molding which forms the lid seat.  Here’s a picture of the extruder die; it’s cut from sheet pvc and supported during extrusion by the round die shown beneath it.  Much trial and error in designing this extrusion… Box MoldingHere’s a bunch of extrusion prepped for box building.  It dries out – DIES! – super fast, so I put it on plastic as well as under plastic. Fresh moldingsThe boxes are just little rectangles.  I have sheet pvc templates that I use to build them. Sheet pvc is a great material for repeated-use patterns in studio.  Mine is salvage from a local electronics manufacturer – it’s used to ship exotic films for chip building – but you can buy it on line or a good craft stores. There are several thicknesses; it takes serious shears or snips to cut the good stuff. Waiting for moldingHere’s a set of little boxes ready to receive their lid-seat extrusion.  As you all know, the most important thing about joining hand built pieces is keeping all the components at the same stage of dryness, er more correctly, wetness. A condition were there is no color change; the clay remains easy to score and “goop-up” with a serrated rib; but is no longer flexible is just right for this clay, a slightly gritty cone 10 stoneware.  As you can see, I don’t perfect the base boxes at this state.  That is so much easier to do hours later, when the piece is ready for final carving. Applying the moldingsHere’s extrusion going on.  I use a little 6″ ruler to measure each piece individually.  There is always a little bit of variation  1/8″ off can spoil the box…  careful! I do not use any joining slip, magic water, or any other such stuff.  If the clay is correctly conditioned none is necessary.  I cut a tiny miter freehand…  decades of sewing prepared me for clay work…  and I can hit it right on every time.  You might like to use a tiny plastic right triangle until you are confident. So…  all the boxes are built; and some have stamping or texture applied in the “flat state” that will be part of the surface.

Now, the tedious part begins – or USED TO begin – the building of dinky lids from four little triangles of clay.  I had thought for sometime that I could press a nice little lid onto a form, but how should I make the form?  Gotta be quick; just a trial, of course.  Wood is a possibility, bisque of course, but how about that crazy pink foam?  I have gained a new appreciation of the stuff because of what my sweetheart Steve makes from it.  Check this out!   Never want to run into the rest of this critter….. Bug head I still have pink foam in studio from days of experimenting with hat-making, to which I will return someday, of course…. Roughing the Block Here’s the first whack at a form for the lids.  Consultation with Steve makes sandpapering the form down a bit the next step… Wearing a respirator would be a good idea; fine particles of this pink stuff are a respiratory hazard, and a potential mechanical irritant to the surface of the eye.  sANDED bLOCK Pretty dang nice!  Took about 10 minutes, mostly because I don’t measure or overthink.  No drying time, bisquing, or other fussing.  Can’t wait to slap some clay onto it…. Lid on Block with RibHere’s a first lid.  I like a very soft rib to smooth stuff; perfect to contour the clay down to the form.  Impatient Ginger!  pink crumbs all over my work area! Cutting the EdgeMy little Chinese wire tool is perfect to trim the slab down to size.  I anticipated that I would do some further fitting, with a small Surform plane tool, so the lid block is a little bit oversized. Built no carvingThe lids are perfect first time through, yippee!  I will dry these boxes under plastic for a few days, and then do final surface design on them.  Production time reduced by the lid form by at least 25%…..

Can you see the lid seat on the box on the right above?  I ran out of extrusion and had to build the lid seat from strips…  I will round and smooth the edges later and they will be just as nice. So it can be done if you don’t have access to an extruder…

Reading over this post before I hit the button and launch it into the world, I realize that what I want to do next is make the series of little architectural stamps that I have been imagining….  little windows and doors, arches and cupolas; all related by scale,  Ooooohh!

Wheel Throwing, Zingdezhen Style….

I’ve been wanting to share some images from a trip to China I made a few years ago.  I went with an NCECA group, and we traveled to the  Porcelain Capitol of China, Zingdezhen.  It’s a small city by Chinese standards,  with about 1.5 million people.  We were told that approximately half the workforce there is involved in the ceramics industry.

There were about 70 of us; potters from all over the United States,  For a  week while we were there, master artisans were brought from all over the region to demonstrated for us.  Here are some pictures of a young man who came to show us wheel throwing, Chinese style, and his two helpers.

In Chinese ceramic industry, there can be strict division division of labor.  I never knew the names of the three guys who demonstrated for us; but one was a thrower, another a trimmer, and the third prepped and wedged all the clay for the thrower.  I can tell you this – they all thought it was completely hilarious that anyone would want to watch them at work.  They were in fine spirits throughout the week, and seemed to be continuously astonished that anyone would be interested in what they did.

The thrower started every day in the same way – by sticking his feet and legs into plastic shopping bags, and then securing the bags around his calves with yellow plastic  tape.  The trimmer did the same.  You can see the bags in this picture….1 The Whole Wheel

Heck with the bags, look at the wheel.  It was on a platform about 20″ high, and the motor was under the wheel head.  You can see a control off to the left for the potter to manage wheel speed.  His bagged feet are set on bats, and the thrower is sitting on a small, square stool.  At left in the photo is the wedger, a slim young guy who just made balls of clay for the thower.  They brought in about 2,000 pounds of clay in pugs for he and the other demonstrators to use; you can see the under the striped sheet – no plastic, just the crazy ambient humidity.

As you can see, the wheel head is down between the throwers’ feet.  I’ve fiddled around a bit in my own studio with this kind of body-to-wheelhead arrangement, and it gives you terrific advantage for large pots.  Without ever having done it before, I could recognize that it was a great  way to make big pots.6 Pulling up the Pot

He’s got almost all the clay here, and is pulling hard off center as he brings it up. His shoulder is right over the top of the pot as he works…  a very  strong position.7 Carrying the ClayNo tools, and no sponge.  He brought this clay up high, and then bellied out a large jar with a tight neck. He had about 12-16 pounds of clay.  Now, for some throwing off the hump…2 Off the HumpStill no tools for this thrower, and he is using the wheel at constant speed.  He didn’t even have a cut-off wire; he just pinched the pots off.  You can see a tidy little foot ring right above the base block.  I didn’t see these cups trimmed, but I assume the trimmer would have put them on a green chuck and trimmed the block off. 4 Trimming 2

The trimmer had his own wheel, likewise down between his feet. The most interesting thing about the trimming process was that the trimmer had a large number of steel blanks about 12″ long, and he made a specific trim tool for each pot form by hand as worked.  He filed each blank until it was razor sharp, and then bent it into the correct form for the vessel.   You can see from the flying scrap that the pot is fairly dry up on the rim, no problem!  The trimmer didn’t want any clay in his shoes, either.5 Tall Trim

Here’s a combined form that the trimmer joined together and trimmed up.3 Born to WedgeThe wedger was the hardest working guy of all, wedging clay and moving the wet pots.  Note the Kareem Abdul Jabbar teeshirt…..

After all that work…  dinner.8 Dinner

Ginger, terrified, plays with fire again…..

It’s been twenty-four hours since I salted my kiln and shut it down last night, and the temperature is still about 900 degrees on top.  It was a good firing, with a steady climb to 2250 F, the temperature I like to reach for salting.  Last evening, I had a friend over who has worked with clay for many years.  It was fun to explain my process and a bit about the history of salt firing as I understand it.  She also took some pictures while I was at work… here’s the best one.

Salting the Kiln

 

I’ve got my respirator on, and the port brick is in my left hand. I just pushed the burrito of salt into the kiln with the stick in my right hand.  Usually there’s not so much flare-out, but my delay in stuffing the port brick back in made for a more dramatic photo.  At that point, it was about 9:30 at night, many hours since I began the firing at 6:00 AM.

The first hours of the firing are quiet.  It’s dark, and the grass is crisp with frost when I go out to the propane tank to turn the gas valve full on.  I have placed the burner stands and burners in position, and their needle valves are firmly closed.  Righty-tighty..  The main ball valve that supplies the kiln is checked closed as well; my Mom’s pipe wrench at the ready to open it.  Dear readers, are any of you fortunate enough to possess your Mothers’ pipe wrench?

Little Blue TongueIn the first hours, the burners are quiet and the kiln makes no sound.  I have nice Hones nozzles that make for a beautiful flame.  I keep a firing log where I record every detail of the firing, logging in the temperatures returned by the top and bottom thermocouples every thirty minutes.  I have cone packs in the kiln, but rely on the thernocouples and the state of the kiln to conduct the firing.

All the protocols of the firing must be carefully observed each time I fire.  It helps me to not be afraid.  I have blown up a kiln; a natural gas caternary arch kiln, and the memory comes to fire with me each time I light up another kiln.  Intellectually, I understand what happened on that Sunday morning long ago, and know that I will never blow up a gas kiln again.  Still, I think of it.  With this kiln, I am most apprehensive at top temperature, when tiny flames lick out of cracks here and there, and I try to estimate the temperature of the 2 x 6’s just a few feet about the arch.  An insulating brick layer and generous kaowool blankets swaddle the arch, providing nearly 15 inches of insulation between the hardbrick hot face and the top of the kiln.  My next kiln shed will be framed with metal; one less thing to worry about.

This load is half stoneware, decorated and painted in my usual manner, and half pure white porcelain.  It’s my little experiment; pots for the Making White show at Valley Art this coming weekend.  I’ve been blogging about these pots, and have really enjoyed making them in spite of the usual problems with porcelain – mostly, a narrow time window to do attachments.  The clay  – Georgie’s Crystal Springs – is obedient, and is a very pleasant throwing clay.  It reclaims well.  I’ve lost quite a few handbuilt pieces, though. It doesn’t like to stay bent and must be dried very slowly.  Nonetheless, half the kiln is white porcelain work.  There isn’t even a flashing slip on it, and it’s glazed within with beautiful flambe blue glaze that yields a glossy, functional lining for cups and casseroles.

A couple of years ago, I fired about six porcelain pieces made in this manner in my salt kiln. Everyone who comes to the studio admires them, so I thought I might someday make enough to sell.  I don’t feel that I can take the porcelain pots to my juried shows, because they will be so different from my jury images.  Some may make it to Showcase, where we OPA members get to show whatever we like.

I kept the white pots together in the kiln, as much as I could, because I  am concerned about all the cobalt that circulates in my kiln during a firing.  Some of the first few porcelain pots show signs of copper flashing, which is rather pretty.  The main source of copper was actually from the flambe blue liner itself, which contains a lot of copper carbonate. I am really eager to see how much pigment moves onto these pots, even though it may spoil them.  Ah, science….  It’s got to be wild in there; 400,000 BTU’s per hour rearranging the molecules of mud.

Here’s the stack – you can see the white pots at the top and bottom.

Stack

Tomorrow about 11:00 AM, I will take out the thermocouples, and with a mallet knock the channel iron bars that hold the door shut out of their rests.  I’ll pull the door, which hangs from a heavy iron I-beam,  carefully out of the kiln about 5 inches so a space is made at the top for heat to escape,  The kiln temperature will still be over 500 F when I start to move the door.  It’s very hard not to pull it out far enough to have a peek into the chamber, but I’ll be resolute.  At 5 PM, I will draw the work and see what useful, and hopefully beautiful, pots have come into the world.

Stiff slab handbuilding with porcelain….

I’m still working on pots for my March show of white salt-fired porcelain.  I’ve got just about enough, but thought I would make a few more handbuilt vases for the load.  I’m working with Georgie’s Crystal Springs cone 10 porcelain, which has turned out to be a decent working clay if dried carefully.  Last night, I sliced a bag into three thick slices and let it start drying – or conditioning, if you will.  I am very particular about the stage of dryness for my handbuilt work.  I work with much stiffer clay than anyone else I know, and make just one pot at time so my clay stays just right.

Sometime back in the 60’s I took Soils 200 at Oregon State University; part of my education as horticulturist-to-be.  I remember that the Cove clay soil – which I was soon to know intimately –  was considered to be the archetypal Oregon clay soil, “2:30 Soil.”  At 2:00, too wet to plow…  at 2:30, too dry to plow.  My handbuilding clay is like that, with a teeny perfect window of time to work.  It has to dry enough to stand, but moist enough to flex a bit and join to itself on demand.

If I am stamping, or using texture mats, I will apply texture when the slab is still a bit soft; then dry it to the same stage as my clay to be carved. If you a reading this because you’d like to try this stiff-clay handbuilding stuff, you’ll have to find your own way with it.  At workshops, I pass bits of clay around so everyone can get a sense of how stiff is just right.

So here’s some just-right clay, twiddled around, covered and uncovered for a couple of days, and rolled out just a hair under 1/4″ thick.  I use paper SlabMat, so I don’t have to remove the canvas texture.1 Layout toolsHere are some of my layout tools, a big right triangle and a quilters’ rule.  The rule is 18″ long.  I want to make some tall standing rectangular vases, so I cut front and back each about 7″ x 12″. The end panels are 3.5″ x 12″.2 Score and Moisten

I don’t use magic water, vinegar, or any of that goo for joining.  I score all edges to be joined with a serrated rib, which is much quicker than one of those silly little metal brushes.  I line the pieces up and stick them together.  You can see that I have dressed the inner seam at the right of the image with the black water-buffalo horn tool – it’s better than a finger.

3 Stand it Up

Here are the two sides and the back, stuck together and standing up.  The clay has to be stiff enough to stand!  I do not use coils, they are a colossal pain and way too much work. These are approach joins, and they work well for me.  I have also beveled the edged in various ways, with various tools that I have gleefully invented, but in the end this method is faster, stronger, and looks just as good.4 Applying the Base

It’s easy to put the bottom on – you can see the slight distortion where the serrated rib has roughed up the clay.  No sweat!  We will fix that in an hour or so when the box/pot has set up a bit.  You can also see that there is a finished pot right behind that has already had strips of clay applied to the top edge to give a more refined appearance and strengthen the pot.  When I was learning to handbuild, seemed like everyone wanted to whack on their pots with wooden tools to strengthen the joins; all that has ever done for me is distort the pots.  Here’s a picture of how the strips go on the top.  If I am in a fussy mood, I will miter the corners by eye, but it works just as well to lay them in square.5 Trim the Top

I did put a couple of stamps on each front and back slab, couldn’t help myself.

Here’s that same pot about an hour later – er, part of it.  I used to try to finish all the surfaces at the time I did the building but have learned to leave the pots alone for a while and clean them up when they have set together strongly – at least 1 and maybe 2 hours.  I  keep a toasty studio in winter  and I keep the pots well away from the stove so drying is even.  6 Rough Joins Ready to Scrape

As you can see, I work on lots of clean newspaper and often on an old bath towel.  These edges are ready to clean up.  I will also take care of that little nick in the pot too, don’t need that….7 Microplane Smooth

The first tool I use is a fine microplane from the cookware store.  These tools are super for handbuilders.  I use mine for dozens of tasks, and they are especially good for working on square work because they are so flat and plumb. It’s fine if joins – or feet – extend a bit; they clean up fast with one of these tools.

The next image is a bit hard to understand, but it shows the tool I use to finish up the joins; a smooth oval rib.  Carefully applied, it scrapes away the texture left by the microplane.  I do like the microplane texture – and use it sometimes to surface small objects.  But I want a smooth surface on these standing vases.8 Oval Scraper

With all the edges finished, it’s time to apply the surface imagery.  Gotta start somewhere.9 Start Somewhere

I’m getting a bit weary of these flowers, but since people still want to buy  the pots I will keep making them.  I am a slave to commerce! 10 Handbuilt Dogwood Fin

Done with this one…  a similar design on the reverse, and geometric figures on this sides.

12 Finished HB Vases

Here’s the group from the work session, about 5  hours in at this point.  You can see that the one on the right is wearing a little bandage to compress the top…  I noticed that the top trimmers were separating a bit, so I filled the void with some very heavy body paste and bound it up with nursery flagging tape.  Every potter should have some on hand….   That pot came out of the bisque a couple of days later with the top tight and perfect.  Incidentally, I always make these pots last to fill my kiln, because they dry super-quick compared to thrown pots.  They are so even in section that they can dry overnight if needed.  I dried these under plastic just because they are not my usual compliant grey stoneware clay.

Here’s the one I like best….11 Geometric Box Fin

A Sunday morning walk…

On Sunday morning, there were a few hours of sun.  The view to west from my back porch was so beautiful that I decided that the dawglet and should take a walk.  I’ve had a project in the works for a couple of years with the local NRCS – National Resouce Conservation Service –  that includes the reforestation of 1.5 acres of my farm.  I thought I would take a walk down there and see if any of the grass seed sowed about a month had survived the recent heavy rains and germinated.

Looking west, December morning.

We walked up through the nursery, and then down the little hill to what’s been called the duck lake.  I learned the name of that place from all my neighbors who showed up, asking to hunt ducks and geese there after I moved here in 1997.  My duck lake is completely encircled by trees, and is considered to be one of the better ones around, not that I would know. My tribe has tofu turkey for Thanksgiving….

 Chi – the dawglet – was cavorting, eager for the outing.  There’s nothing she likes better than to accompany rounds in the nursery, looking at crop.  But  a walk in the woods is better than anything if you are a terrier.

Coming down into the duck lake, I could see that my grass seed was surely goners.  The entire area was covered with straw that had floated in last week when the the first episode of the winter monsoon was upon us.  I didn’t have access to a real drill – we just broadcast the seed and dragged it.  the NRCS had specified that row spacing for my reforestation trees should be 8 feet, meaning that all the 10 foot wide tillage equipment of my obliging neighbors was not usable.  Sigh.  There was still quite a lot standing water down there…

Impondment

As soon as I took the picture above, Chi raced head.  The peace of the morning walk was forgotten.  To my surprise, there was a duck hunter!

Larry

Aw, it was just my new best friend Larry and his dog Sally.   I explained to Larry that it was my farm and there would be no murdering of ducks.  Larry was deaf as a post and I don’t think he understood a single word I said, but he did tell me all about Sally’s recent operation – the $1,700 one, not the $4,000 one – for a torn tendon in her right hind leg.   Sally is half Chesapeake Bay retriever and half lab, and she’s only 18 months old and already a really good bird dog, so why not?  He and his wife were brokenhearted when their last dog died, and they were really happy to find such a good pup even though they’ve always had purebred dogs in the past.

Then, he must have realized I was still talking, maybe trying to tell him something, maybe that he couldn’t hunt on my land, and he started a completely bullshit story about how Dave had sent him to gather up all the lumber that they had gotten together to build a new duck blind on the property just to the west of mine.  The lumber – which was evidently railroad ties – had floated down into my woods, riding floodstage Dairy Greek south with the straw.  I have to say that he didn’t look exactly like he was out to reclaim wood, what with his brisket decorated with duck calls and his stylish camoflauge-painted shotgun.  I guess when you dress up to murder ducks you take your hearing aid out.

duck call

I asked him about the duck calls and he gave a toot on each one of them. Sally was very excited, but Chi was off varminting and could have cared less.

I shook his hand like a man, and headed home to get ready to go to Portland and go sell pottery.  Chi was content with the outing and came along home to spend the day on the couch.  By the time we were home, it was raining steadily and the sun was gone.

Camo Chi

Here’s the dawglet in full camo……

Still thinking about stamp-making….

Popular Science magazine, which used to be an airport-only treat for me, now comes to my house every month by post. I love to read about new materials, engineering innovations, and all the other stuff that they cover. For me,  it’s a workable antidote to the The Great Ennui, the creeping doomview that seems to be my brain default all too often these days.

I’ve been especially interested in 3-dimensional printing, even had a little fun with the idea a few years ago when I made the so-called “Little Men” – the 6 tiny sculptures  that I called The Ratmasters.  I took them down to Ceramic Showcase and put a fairly preposterous price on them because I really didn’t want to sell them until I could think about them a bit.  My forays into non-functional work are so infrequent that when I make something that isn’t strictly practical it sort of astonishes me.  Here are the first two that I made, they still live in my studio….

Here’s a teeny story I wrote to propose origins for them – you hardcore sci-fi fans out there may like this….

What is known about the six small objects, SUO 315 01-06, now known as the Ratmaster Commemoratives?   Although much uncertainty remains about their origin, it can be confirmed that they were created from data recorded within an object found in an agglomeration of orbital debris near the center of Space Unit 315/396W.  Sent for routine recycling, the object now known as the Unit 315 Cone did not correspond to the spectroscopic profile of any terraginous material, and was sent to the International Laboratory for analysis.

The Cone is a deep blue conic form 10.73 centimeters wide at the base, tapering to a point.  It is 22.58 centimeters long, and weighs 188 kilograms.  It has several unique properties.  Not only is it uniquely heavy, it is geotropic and will rebalance itself in a vertical position on its base when not restrained in a horizontal position. 

Sector 315 Cone was registered as a Special Security Property, and was extensively studied.  Attempts to remove samples from the object by cutting or drilling were eventually abandoned, and all available scanning modalities failed to reveal any internal structure.  A translucent box was built for the Cone, and it was placed on display in the foyer of the International Laboratory Visitor Center.

Four years after the Cone was placed on display, an unknown event triggered the release of a data stream from the object.  A security guard on routine night patrol observed a luminous beam emanating from the Cone.  The beam described a circular pattern around the Cone; moving in a slow, sweeping motion.  Scientific staff was summoned, and the Cone was returned to a secure area so that the beam could be studied. 

The beam emission was found to consist of pulses of light, which were converted to a binary graphic stream.  Data release from the Cone continued for fourteen months, at which time it stopped.  At that point, a pronounced change in color of the Cone’s surface was noted.

The data was sent to a secured location, and an extensive server farm was constructed and dedicated to deciphering the data stream.

 An international team of decryption experts monitored reports from the computers.

Once the downloading of the Cone data was complete, linguistic analysis and decryption of the contents began.  It became apparent that two semantic systems were present in textual portions of the information.   Much of the data was in the form of numeric tables, which were in due course recognized to be climatological and hydrologic reports.  There were also records of equipment acquisition and maintenance, purchase orders, salary payments, and other transactions.   In each instance, there were paired reports, in each of the unfolding languages, describing the same occurrence.

It began to be clear that the information contained in the Cone was a periodic dispatch from the colony of a still-unknown nation or planetary state, identified only as Origin, and was concerned with the most details of elemental every-day governance.  The colony was referred to as Srad 3/50 in the correspondence.  

On e of the languages began to emerge as that of a diplomatic class, and was called Cone SS-A.  The other was determined to be a language different from Cone SS-A, and was recognized to be unlike any ever studied.   It was called Cone SS-B.  Cone SS-A was found to have properties common to many extant world languages, but was closest in structure to an archaic form of Arabic.

Data from which the Ratmaster commemoratives were derived was one of the last information units to be deciphered.  The code was acknowledged to be unique machine language, and was ultimately determined to be of two types – textual and algorithymic. 

Many tests were run on the algorithmic data, and at last a pattern appeared. A researcher with avocational CGI experience recognized the code as instructions for three dimensional printing, a modeling modality developed in the first decade of the century.  Further decryption confirmed this analysis, although the process for printing and the material specifications from the Cone itself are still under study.

Developers of the original three dimensional printing process were brought into the research project, and work began at once to learn if the code could be used to create image-objects with existing three dimensional printers. Other scientists continued the study of textual materials.

It became apparent that there were six blocks of information of each type, as well as one that was thematically related to the six smaller blocks, yet more extensive.   The text blocks were language Cone SS-B.

The large textual block was deciphered first.  It consists of prologue, argument, and conclusion.  The prologue is an address to a yet-undetermined governing body, with a recapitulation of a temporal period of events.  It is formal, yet obsequious.   The argument states that the Council of Citizens is making a request on the behalf of six Agency Administrators, asking that they be allowed to remain on Srad 3/50, rather than returning to Origin for decommissioning. 

The text notes that retirement documents for six Administrators had been received, and that commemorative portraiture busts were commissioned, but that the Srad 3/50 Citizens Committee had granted these individuals special service recognition by designating them as Citizens on their commemoratives.  According to the text, upon learning of this honor, the six Administrators – the term Ratmasters first appears here – requested that the Srad 3/50 citizens committee advocate for their retirement on the planet.  Data for creating the image-objects was embedded in the text this point, and was adapted by a team of analysts and these commemoratives were created.

Anyway….    it’s possible to have objects formed by 3-printing without purchasing a 3-printer.  Joe, my technology mentor, suggests that I learn to use the software, and send my designs off for fabrication for a while.  He gave me the name of an online company to contact.  Makes the head spin a bit to think about 3-drawings to send it to them.  I think much finer stamps might be possible this way than by whittling on green clay.  I am keen to get some of the actual “plastiscus” and see how it stands up to groggy clay.

In high school, a llfetime ago, I learned to make working sheet metal drawings – INK! – in mechanical drawing 2.  Gotta get the head back there. If you are interested in this stuff, here’s a link to a recent Popular Science article about 3-d printing.
