What Do you Think of Charcoal as Forge Fuel?
Charcoal was the original forge fuel. It is realtively clean and smoke free and reaches all the temperatures required to forge or weld with.
Originally charcoal forges were side draft not bottom draft as coal forges are.The main draw backs are the cost. Either cost in producing your self in time or cost in dollars to buy premade.
The other drawback is that you will use a lot of charcoal volume wise but it will work out to about the same weight as coal.
