|Peeking in the kiln is addictive|
My kiln fires unevenly, so I loaded the kiln such that the clays that don't like as much heat are in the back of the kiln and the clays that can take the heat are in the front of the kiln. Basically, the high-iron clays don't like as much heat, so they are in the back of the kiln, but a few made it toward the front of the kiln as well. The middle of the kiln is mostly a clay from STARworks called Okeeweemee 10 which is a dark clay body which has bloated in the front of my kiln before but seems to take more heat than my local high-iron clay. But there are a couple of pieces in the front of the kiln made from Okeeweemee 10. I think some of us potters like to take chances.
My wood kiln is designed to produce a lot of melted ash and flashing effects on the pots. Flashing is when you get subtle colors of sheen that develop on the outside of the pot. The way you load a kiln affects the way it fires, and with a wood kiln, it affects where the ash deposits occur and the flashing. It's one of the main challenges in loading a wood kiln such as the one I fire. I decorate some of my pots with trees, vines, etc. so I have to think about these things.
I put a small cup made from some of my high-iron yellow local clay right up front in the kiln when loading it, where it would likely get blasted by flame and ash. You can see it to the right of the tall vase at the left. It might have bloated, but it appears okay. I'll be checking it out tomorrow some time.
