Coal Forge Guide
A coal forge is a type of forge that uses coal as the primary fuel for heating metals. The basic design consists of a firepot, where the coal is burned, and a tuyere, which is a tube or pipe through which air is blown into the firepot to increase the intensity of the fire.
Using a Coal Forge
The first step is to start a fire in the firepot. This can be done using a variety of methods, such as using a blowtorch or a propane torch to ignite small pieces of coal, or using a starter fire made of charcoal or wood. Once the fire is going, it is important to continually add coal to the firepot to maintain a consistent heat.

Benefits of a Coal Forge
One of the benefits of using a coal forge is that it can reach higher temperatures than a gas forge, which allows for more intense heat treating of metals. However, it is important to note that the heat is not as consistent as gas forge and it is harder to control the temperature.
Safety Tips
When using the forge, it is important to have proper ventilation to remove the smoke and dangerous gases produced by the burning coal. This can be achieved by installing a chimney or exhaust system, or by positioning the forge near an open window or door.
It is also important to use the proper safety equipment. This includes wearing heat-resistant gloves and goggles, as well as having a fire extinguisher nearby in case of emergencies.
Choosing the Right Coal
One important aspect of using a coal based forge is to use the right type of coal. Bituminous coal is the most commonly used type of coal for forges. It burns hot and long, which is ideal for forging. It is also important to use coal that is free from impurities, such as rocks or dirt, as these can damage the forge and make it difficult to control the fire.
Firepot Cleanliness
When using a forge, it is important to keep the firepot clean. This can be done by using a fire rake or a pair of tongs to remove any excess ash or clinkers that may have formed. The firepot should also be cleaned periodically to remove any buildup of soot or creosote, which can reduce the efficiency of the forge and be a fire hazard.
Summary
Overall, a coal forge is a useful tool for blacksmiths and metalworkers, as it allows them to reach high temperatures needed for certain metalworking projects. However, it is important to use it safely and properly, and to have proper ventilation and safety equipment in place.
