Blacksmiths usually use coal in their furnaces, others use gas, and still others use charcoal.
I read that a good feature of charcoal is its environmental friendliness, cheapness and the ability to make charcoal at home.
I read a few DIY charcoal making tutorials and chose the easiest and cheapest method.
Production history
In order to answer the question of what is required for the production of coal, one should turn to the history of its production. The first producers of such coal dug special pits for it and burned firewood in them.
Subsequently, firewood began to be piled up and burned on special sites. This production technology was called charcoal, and in some industrial enterprises it is used to this day.
Today, the improved technology for the production of charcoal is called pyrolysis. It is distinguished by better insulation of materials from oxygen, and also provides optimal thermal conditions for a higher quality final material.
