coal forge

A coal forge is a type of furnace used in metalworking to heat metals until they become malleable and can be shaped or forged. It consists of a firepit where coal is burned to create high temperatures, a blower to increase airflow and intensify the fire, and tools for manipulating the hot metal. The coal produces a strong, hot flame that is essential for processes like bending, shaping, and welding metals. Blacksmiths traditionally use coal forges to create tools, ornaments, and other metal items, relying on the forge's heat to transform the raw material into finished products.
