A firing technique used by necessity in many countries and by choice in others. A properly designed kiln wood is capable of delivering high temperatures and so it is possible to make stoneware and porcelain. The kiln chamber in a wood kiln subjects the ware to a lot of ash and smoke.This affects the appearance of ware in a way that is prized by many potters and users of their ware. It is even possible to fire pieces without glaze and the products of combustion of the wood will deliver enough fluxes to fuse the surface of the clay in a glaze-like manner.
