Dear liz: I hear ya babe! all the above is true and your advice is sound.
Just when I thought I was King Shit of Turd Isand i had a completely orange
firing. Just as you said I think the glaze was an arm pit hair too thin.
The width of a hair can make such a difference. I bought bigger shelves,
extended my chimney by a foot, had a firing of big ware, glazed the insides
first and all in all created too many variables for one firing. One thing
that came out amazing was Redart terra sig under shino. Lusterous just like
the black velvet of ceramics-the dreaded RAKU.
good pots to ya and may your thumb always be black.
cheers,

We tried a plain ole iron wash UNDER our shino on porcelain and got some
lustrous gems out of the wood kiln last week. I remember being told in
grad school that you should spray an iron wash OVER shino not under.
who knows?

ps. It snowed last night on my 700 daffodils which were in perfect
bloom. now they are drooping. Don't know if they will come out of it.
I think I'll move to Holland and grow tulips. The deer eat tulips
here. I wanna neighbor with Russell Fouts across the Belgium/Holland
"state" line and give him hell instead of Mel.
