I've had trouble with bloating using Standard 266. I know I'm not the first person to have this issue, but my options for preventing it are limited. I fire my pots in a community studio, so can't change the firing schedule (we bisque to cone 06 and glaze fire to cone 6, both in an electric kiln). Is it reasonable to assume that putting a piece through the bisque again will burn out the remaining organic matter, and therefore prevent bloating? I don't know the exact bisque firing schedule, but it takes around 15-16 hours. Are there other reasons this clay bloats? Other potters in the studio I use have used Standard 266 without bloating, but their pots have thinner walls. The other difference is that I used metallic black glaze on the pots which bloated, while the other potters didn't, if I remember correctly. I'm not sure if this makes a difference in trapping pockets of gass though, especially since I left the outside unglazed, but had bloating on both sides. I should add that I'm not going to be using this clay anymore (mainly because I'll be leaving the US soon), so I'm just looking for a solution that will work for one specific pot, which has already been bisque fired. And yes, I now know the importance of testing a new clay body before using it for a pot you care about.
