forge

A forge is a specialized furnace used by blacksmiths to heat metal until it becomes malleable. Once hot, the metal can be shaped, bend, or joined through hammering or other techniques. Forges typically use coal, charcoal, or gas as fuel, creating high temperatures necessary for working with metals like iron or steel. They often include a bellows or blower to increase airflow and heat. Forges are essential tools in metalworking, enabling artisans to craft tools, hardware, or artistic pieces by transforming raw materials into finished products through controlled heating and shaping.
