I have the butter dish mold. Yesterday I did the Base and it cracked. I put in 18 oz. of coe96 glass then fired it using the schedule that was on the web site. I've done this a few times and ended up cracking the one mold. I've looked at it at full fuse and looks good, and I've looked at it once it cooled down and has shut down and good then but crack once its completely cool. Fired again and didn't look until completely cooled down still cracked. I don't know what else to do here. Have a few people wanting one.
