The best blue celadon I've seen. A beautiful transparent strong blue color.
Best on grolleg porcelain. You can see a fine example of this glaze on page=
57
in Lark's =22Wheel Thrown Ceramics=22.
All of these glazes were fired in a Alpine 24 cu ft updraft. We reduced =
heavily
starting at cone 012 ( I was a little concerned with black coring the few =
dark
stoneware pieces in the chamber, but no problem) until cone 05 dropped and =
then
in light reduction up to cone 10. The total firing cycle was about thirteen
hours.
I hope this helps. Good luck=21

could you send me a copy too?
Thanks,
