bowl furnace

Quick Reference


A shallow dish‐shaped depression, lined with clay, in which metal ores were smelted or heated for forging. Examples were typically between 0.25 and 0.4 m in diameter. Air provided from a pair of bellows was forced through a tuyère into the burning fuel, usually charcoal, in the centre of the furnace. Some bowl furnaces were wholly or partly covered by clay domes in order to retain more heat within the structure.
