noun | kiln | kiln
An oven or furnace capable of holding hot fires and maintaining the heat necessary to drive nearly all moisture out of something heated in its interior.
In art, kilns are used to fire clay and porcelain pieces to their hardened final states in what is known as the bisque firing. Next, a glaze firing is used to affix decorative glazes. Due to the extremely high temperatures needed to successfully fire either of these processes, they would not be possible without a kiln.
