Is clear glazing a dark burning oxidation stoneware a good idea? Likely not.

Friday 29th May 2015

Dark bodies tend to have more carbon impurities and the burnout of these can generate gases that create bubbles in the glaze. Because of the dark background, the bubbles impart a muddy look. The body on the left is a finer particle size, so the lower thinner glazed section is a partial success, but the upper section is insight-live.com/glossary/184">bubbling. The body on the right, although a more pleasant red color, is bubbling worse. Notice also that the warm color of the body is at least largely lost under the glaze. At its worst pinholes can appear.
