Kiln Related Flashcards
Kiln
A furnace designed specifically for heating clay to the temperatures necessary to make it permanently hard and stone like. Kilns can be electric, natural gas, wood, coal, fuel oil or propane. Materials used to heat the kiln can affect 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 moth balls into the kiln.
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).
Cone
A mixture of ceramic materials that is designed to soften and bend when the proper mixture of time and temperature is reached in the interior of the kiln.
Cone Plaque
Is a small clay cone holder used when cones are placed on the shelf of the kiln to stand.
Cone Temperature
Is the mixture of time and temperature at which the cone will bend to show the kilns temperature on the shelf.
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.
Shelf Cone Temperature
The cone temperature that is fired on the shelf of a kiln. The amount of heating the ware actually receives.
