Colored slips formulated to have low drying shrinkage, allowing application to bone-dry or bisque-fired surface before glazing.
Very low temperature (cone 018) glaze colors applied over a previously fired higher-temperature glaze. Allow greater detail, brighter colors than other ceramic glaze effects, but are vulnerable to surface abrasion. Source: Clay: A Studio Handbook
Any of a group of slightly over 100 substances on earth that may exist as individual atoms, and from which all materials on earth are composed.
A self-glazing clay body in which soluble alkaline fluxes effloresce to the surface as the piece dries, and subsequently form a thin glassy coating in the firing. Source: Clay: A Studio Handbook
Formation of crystalline deposits on surface of clay or concrete as soluble compounds migrate to surface during drying. See Egyptian paste. Source: Clay: A Studio Handbook
Natural low-fire secondary clay—fluxed with iron, fires porous. Often called “common” clay, found almost everywhere, matures below 2000°F. Source: Clay: A Studio Handbook
Low-fired ware, usually still porous after firing—must be sealed with vitreous glaze to be functional. Source: Clay: A Studio Handbook
Traditional term referring to serious cracking occurring in cooling, resulting from drawing too soon, from extreme excessive glaze-compression, or from low thermal shock-resistance in overvitrified wares resulting from overfluxing and/or over-firing. Source: Clay: A Studio Handbook
Electric-drill-mounted impeller-mixer excellent for mixing glazes, slips, and slurries and for blunging casting-slip. Source: Clay: A Studio Handbook
The removing of wares from a kiln. Source: Clay: A Studio Handbook
