Bubbles ?
I’m not sure if the actual term when the glaze has small bubbles I applied 3 coats of mars crystal glaze I think it’s amaco the glaze looks really nice however it does run I’ve noticed but my question is why does it bubble I’ve read that clays with grog have a higher tendency to burn off stuff making the glaze bubble from gases trying to escape but I use porcelain idk I like this glaze and my test came out not good I don’t know if there are any tricks to prevent this (I also only glazed the top 3/4 of the piece it runs a lot)
