First I must say that being connected to so many potters is a wonderful
thing!
I have a gas kiln that doesn't want to go to ^10, except occasionally on
the bottom. When this happens, the top is at a low ^8. For that reason,
and to save fuel and time, I would like to lower the temperature of my
firing. I have done this successfully in my electric kiln, but I don't
know if the same approach will work in reduction.(I added frits)
I would like some formulas that are known to work at a lower temp to use
while experimenting with altering my existing glazes. Going down to ^6
would be great, but I would settle for ^8. Does anyone have any experience
or ideas?
