Four types of silica, namely potter's flint, diatomaceous earth, chalcedony, and fused silica, plus pyrophyllite, were substituted in typical fritted, Bristol, and porcelain glazes. After firing over a wide range of temperature, the following glaze characteristics were evaluated: maturing temperature, maturing range, surface texture, defects, and glaze fit. Results indicate that diatomaceous silica is decidedly superior to the other silicas as a primary glaze constituent. Chalcedony and fused silica also appear promising, whereas potter's flint and pyrophyllite are less satisfactory sources of constituent silica for glaze compositions.
