Kiln Flashcards
Element
The heating coils of an electric kiln.(Tired or burned-out elements refer to elements which carry too little or no electrical current for producing heat.)
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 material is available. Kilns allow a more efficient use of materials and more control over the atmosphere during a firing. Firing has two basic atmosphere. Oxidation Reduction, these two atmospheres will affect the color of the final piece.
Kiln Wash
The refractory coating applied to the top of the kiln shelves to protect them from glaze drips.
Peep Holes
Small holes in the side of a kiln used for viewing shelf cones and ventilating the kiln during the firing process.
Posts
Articles made of refractory material which support kiln shelves during firing.
Vent Holes
Small holes made by puncturing the wet greenware with a needle tool when two pieces of ware have been attached. These small holes allow the air and gases to escape during firing. Also refers to the peep holes in the side of the kiln.
