Q.My previous pots had blisters and I’m not sure why.  Do you know what causes blisters?

A. Rapid cooling sometimes.

Incomplete bisque firing or single firing sometimes

Soaking at glaze melting temperature can alleviate issue.

20 or 30 minutes of hold should help.

Alpine Clayworks use Bartlett’s ‘slow bisque’ default schedule for that reason.
