  1. Glaze:
    • glass-forming chemicals, usually with coloring compounds added, that is applied in a liquid form
    • to bisqueware clay and fired in a kiln, forming a pleasing coating around the surface of the clay. When
    • glazes are applied, they are usually not the color they will turn out to be. When fired, glazes go through
    • chemical reactions, causing them to change color and turn to glass, fusing to the clay.
  2. Gloss Glaze -
    a type of glaze which creates a shiny coating on a clay surface
  3. Matte Glaze -
    a type of glaze which creates a flat coating on a clay surface
  4. Underglaze:
    • colored slip, which is painted onto either bone dry clay or clay which has been bisque
    • fired. After applied, a clear glaze is applied to the surface, which seals in the color and gives a glassy
    • finish. Unlike glazes, underglaze usually remains the color it is when you apply it to the clay surface
  5. Crawling:
    • a bare spot or the shrinking back of glaze on a ceramic surface, usually caused by dust or oil on
    • bisque ware, or too fast of a warm up during firing
    • Crazing: the cracking of the glaze on the surface of the pottery caused by cooling too fast or pooling on too thick
  6. Refractory:
    ability for a material to resist high temperature
  7. Flux:
    a melting agent causing silica to change into a glaze
  8. Grog:
    fired clay that has been ground into course grains to help reduce shrinkage and warping
  9. Oxidation:
    firing with a full supply of oxygen. Electric kilns fire in oxidation. Oxides show bright colors
  10. Reduction:
    firing with reduced oxygen in the kiln
