Introduction to the kiln

A kiln (kiln; furnace; oven) is a device made of refractory materials for firing products. It is an essential facility for pottery molding. It has developed from the open-pit burning and digging pits of primitive society to the steamed bun-shaped raised-flame round kiln, semi-inverted flame horseshoe-shaped kiln, half-slope dragon kiln, and duck-egg-shaped kiln, to today's indoor gas kilns and electric kilns.
