Japanese Noborigama Kiln Pottery Pin

Noborigama (Climbing kiln) (登り窯) "Noborigama" these days generally means a kiln with a partitioned chamber for firing large quantities of ceramics and other ware, built on a slope so that gravity draws the flue gas through the kiln, keeping the high temperatures constant throughout the chamber. This kiln works particularly well for manufacturing uniform goods when the surface of ware is coated by glaze. Before the development of transport systems, Noborigama was constructed near to where the ware would be sold or in places abundant in the raw materials of clay, fuel and water.
