Such pot bellows had been constructed with a large rim, so that the hide overlaying would transmit a maximum amount of air when pumped. The covering was fixed to the pot with a wire beneath an out-turned rim, or in a groove just below the rim exterior. An opening close to the base served to insert a pipe of pen shapable material whose purpose was to direct the air blast to both the furnace or crucible, and which was often done by way of the mediation of a tuyère. Tuyères used in conjunction with pot bellows had the function of protecting the ends of perishable tubes leading from the pot into the fireplace. Piston bellows were independently developed in the course of the 18th century in Europe.
