Blistering
When a glaze has a 'bubbled', lava-like surface, this is called blistering. Some so-called 'lava glazes' are specifically formulated to blister. Normally this effect occurs when gases released from the glaze become trapped in the glaze matrix before they can escape and the glaze smooth over. This can be due to undefiring or overfiring.
Remedies:
· Fire the kiln slower
· Reduce kiln atmosphere less
