Red burning clays bubble glazes more


Tuesday 11th November 2014

A closeup of the rim and a transparent-glazed cup made from a high-iron clay (Plainsman Redstone) and fired at cone 6. Iron-bearing clays tend to gas more on firing and can generate many more bubbles in glazes for this reason (a buff insight-live.com/glossary/85">stoneware would be almost free of bubbles with this glaze, Plainsman M340 transparent). Thus, it is best to use opacified glazes with this type of body.
