Same glaze, different glazes, new batch, etc?
It is the clay body itself just under the surface - under the glaze. The glaze is the majolica cone 6 from mastering cone 6 glazes. I fire to 2170 with a 20 minute soak and then fire down.

I have used that glaze without any problem on a raku clay body fired to ^6 in electric.
See what a witness cone tells you.
