does anyone have any advice concerning ash glazes? The particular problem I am encountering is when applying the glaze to the bisc, having it retract and crack up, this can (not always) make for bare patches. The problem seems to be mosre so when superposing (in this case on a tenmokou). Any advice in general in this domain would be greatly appreciated as I am just starting out and it is an area which interests me greatly.
Best wishes,
Alistair.
