Scope note
An apparatus that produces a blast of air to a furnace or a forge by means of falling water, and that separates the air and water at a secondary stage. Specifically, a blowing apparatus with no moving parts used in Italian, Spanish and other Mediterranean countries' metallurgical plants until the 19th century. A blast of wet air is supplied to a furnace through the action of falling water, which carries air downward by means of the Venturi effect to a barrel where the air is separated and sent through a pipe, or "tuyere," to the furnace.
