Did a test , fired the kiln Monday.... Opened the kiln Thursday,, Not hot,
bare hands to unload , even the kiln shelves..
Its Saturday nite.. I had a small hand slab bowl that i tested with Shaners
Oribe. I brought it to the kicthen to put some lime juice on it. That didnt
happen ,, We were watching TV , then CRACK,, The glaze popped off in a couple

Hi Gene,
Two things - I recommend sieving through 80 mesh - that may help eliminate
some of the larger bits that crystals form on - and - because flat pieces
cool slower you can get more crystallization - try keeping the flat stuff
off the shelf a bit - try coils or balls of clay - so they cool a bit
faster.
I can redo that glaze with other materials - you would need to tell me what
other spars you have and any dolomite? I would need the analysis for that.
Send me the recipe for the Willie helix and I'll take a look.
There is no way I can make the high copper glaze stable and keep the same
look - perhaps you could ask on clayart for something that is more durable
with the color you want.
