First You See It Then You Don't: Raku Glaze Stability

Kyanite, 35, 50 or 100 mesh, 3%, more or less. As available in North America, zirconium spinel is a very fine crystalline powder that melts at very high temperature, above 1500oC, and will not likely become an active glaze component until 1300°C. In a raku firing, the tiny crystals likely remain inert and float/disperse in the molten glaze; on ...

Gerstley Borate

Gerstley Borate has almost no Al 2 O 3, this is a problem because glazes need it and Al 2 O 3 is normally sourced from clays, especially kaolin. But since GB is so plastic, adding more plastic materials to a glaze causes excessive drying shrinkage (producing cracks and ultimately crawling). One solution is to use calcined kaolin.
