kiln
A furnace designed specially for heating clay to temperatures necessary to make it permanently hard and stone like. Kilns can be electric, natural gas, wood, cool, fuel oil or propane. Materials used to heat the kiln can effect the work: wood ash can build up on the surfaces of a piece and form a glaze at high temperatures. Some potters introduce chemicals into the kiln to influence the effects of the firing. Famed ceramist Beatrice Wood achieved a luster effect by throwing mothballs into the kiln.

Firing
Clay is hardened by heating it to a high temperature, fusing the clay particles . Primitive pottery is usually fired on the ground or in pits with whatever flammable materials are available. Kilns allow a more efficient use of materials and more control over the atmosphere during a firing. Firing has 2 basic atmospheres. Oxidation and reduction, these 2 atmospheres will affect the color of the final piece.
