Had same problem til it was explained to me that kiln sitters (small
cones) bend at a lower temp ( or total heat work really) than the bigger
witness cones. Now I put an 03 in the sitter and the 04 witness drops to
its knees.
mocain. Hotlanta.Ga and just back from the UK where it was equally hot
and the natives were browned off with it!!

Hello,
I have to agree with Ron about the use of a higher bisque temperature. But
if you are bisquing at a lower temperature and it is working for you keep
doing it. We have found that a lot of problems, especially in the glaze
area, are solved with a higher bisque temperature. The cost of firing a
little higher is minimal in most situations.
Best regards,
Tim Frederich

What problems are you referring to and how much higher are you taking the
bisque?
I have a terrible time glazing when the bisque has gone above about ^04. The
water from the glaze is not readily absorbed into the clay body, resulting
in a thin glaze coat.
For our glazed work, I run the bisque to ^06, but for our unglazed,
burnished surfaces, I am running ^08 to ^07.
