Fall 2014 Wood Firing Continued

The unloaded pots have now been hammered, moved inside the studio, or are getting refired. The ones that have been moved inside the studio are starting to get cleaned up and polished, in preparation for next spring’s shows.

All in all, there were some 750+- pots in this load. I’m not sure of an exact number because I started smashing before I had a count.

Here are some of the pots that I started cleaning up today. Most of them are small  dishes, ranging from 10 – 17cm across.  All sizes listed are width, and are approximate measurements.

2014 Fall Firing: Unloading the Kiln

Here are images from Saturday’s unloading of the kiln.  Some good, some bad, but mostly good.

Most problems came from mistakes made with clay or glazes, the firing of the kiln was exactly how I planned… first time ever.

Got a nice gradient from about cone 12-13 in front, to cone 6-7 in the back of the first chamber, and an overall cone 6-7 in the rear chamber.

Biggest problem was crawling of iron brushwork on raw ware. I will touch up bare spots and refire these.

Lost both big slabs, which both cracked BADLY.

Madara  and E-Madara items came out really nice overall, with lots of subtle blues.

Kickwheel Conversion Finished

The kickwheel conversion is finally finished. Here are some pictures of the flywheel getting put together:

Douglas Fir beams glued up and drying.  After drying, knocked the corners off with a chainsaw, then knocked off corners again to get a basically round shape.

And it was just as easy as that.  Many thanks again to Yamaguchi kun for making the flywheel armature!

And here I am taking it out for a spin:

I have this recurring nightmare…

before every firing of the wood kiln. Actually it is four separate recurring nightmares. In the first, I am loading pots onto normal wood shelves in a fairly standard living room, for some reason not worrying that the lot of it will burn up with the entire house. BUT, for some reason, I always remove all of the lamps and light fixtures, because they and they alone can’t handle the  high temps.

In the second, we are firing the kiln as usual, and we are into the third day, just hours before finishing and I realize that I FORGOT TO LOAD THE KILN… This one is by far the worst of the dreams. The feeling of sudden panic is positively sublime. Very happy to wake up (and realize it was just a dream) after this one…

The next is not quite as bad as the previous, but still pretty unsettling.  It starts out well enough: I have just unloaded a very successful firing and am so happy with it that I decide to fire again. Because it is a dream, I miraculously have enough glazed ware to load the kiln up again in about 2 days (Normally takes me 10). I get everything loaded, and start the fire, but about a day into the firing I realize I ONLY HAVE ONE DAY WORTH OF FIREWOOD! This one also wakes me up with that icky panicky feeling.

The third is not a nightmare per se, but a recurring dream about a kiln that doesn’t exist. It is a large single chamber, with white interior, and there are shelves on the walls and in the center of the large chamber on a sort of island. The floor, walls, and island are all white and rough with kiln wash. There is no chimney, and the kiln is connected to the fire box via an elevated brick tunnel, which goes out the rear of the chamber about 2 meters, turns 90 degrees right, stretches about 8 meters, then takes another 90 degree right turn, where extends forward and turns into the firebox. From the firebox to the kiln forms a large U shape. Even more strange, the firebox is open to the sky and steps up to the flue channel, which somehow ‘sucks’ in the heat of the fire. The firebox is probably 4 meters long/deep, and the wood used is huge: entire tree trunks shoved in and stacked in a criss cross pattern, burning.  Any one have a kiln that looks like this?

Coming up to this fall firing in Oct., I feel as though everything is under control, and no particularly strong feelings of anxiety, yet the dreams continue, including 2 nights in a row now, a dream of some of my teeth falling out. Seems quite normal in the dream at least…

Finishing Up The Rear Chamber

Today  the second chamber was finally finished.  I’m not going to brick it in yet, since I have probably forgotten something important, and I want quick access if necessary, until the fire is actually lit. Unbricking an rebricking a door would be on my list of less than desirable ways to spend a day.

While the farther stack was packed with more vanilla type blended clay bodies, this front stack is mostly bodies composed entirely of native clay and stone. Some of it got white slip, but it all got the same clear glaze, so I don’t have to guess too much about temp in the rear chamber when I fire.

Below are some pics of brush deco, slip, and loading. I am happier with a lot of the brush work this time around, but some things still just give me fits, like trying to draw long fluid shrimp whiskers on a round pot. Gah! Need more practice…

Bisque 素焼き

Today is the first load of bisque aimed at the fall firing of the wood kiln.  About 28 ware boards worth of pots, I really tried to get as much packed in as possible, to maximize the gas used.

I don’t pack glaze firings very tight because I want the calories getting around to  everything, but for bisque I’m not too picky.
700C – 750C is my usual peak temp,  I like the ware to be very absorbent for glazing, however the resulting ware is quite fragile and needs careful handling.

This time around there are quite a few slab plates of various shapes and sizes, which I am a bit worried will crack. These are stacked on spacers, then more spacers between stacked plates, because I don’t want to take any chances with cracking. The rest of everything is pretty safe, so packed and stacked without too much thought other than to get as much in as possible.
