Hello,
I am hoping to leverage some good experience from potters with more know how than I. I have a Paragon electric kiln, and use commercial glazes (Duncan, Amelco, Coyote, and Spectrum. I fire to cone 6.
From time to time, and with what seems like without reason I get bubbles and or pimples in the glaze. I like to think I’m fairly careful not to let foreign material infect the glaze.
Any thoughts on what cause these issues? Overfire maybe?
thanks in advance
