Forge bellows

Definition

Forge bellows are mechanical devices used to supply a steady flow of air to a forge, increasing the temperature of the fire to facilitate the smelting and forging of metals. These bellows operate by drawing in air and forcing it into the forge, enabling blacksmiths to achieve the high temperatures needed for metalworking processes. Their design and functionality played a crucial role in medieval metallurgy, significantly influencing the efficiency and effectiveness of metal production.
