Explanation:

• Charcoal is a lightweight black carbon residue produced by removing water and other volatile constituents from animal and plant materials. Charcoal is usually produced by slow pyrolysis—the heating of wood or other organic materials in the absence of oxygen. This process is called charcoal burning. The finished charcoal consists largely of carbon.

Charcoal is usually produced by slow pyrolysis—the heating of wood or other organic materials in the absence of oxygen. This process is called charcoal burning. The finished charcoal consists largely of carbon.The advantage of burning charcoal compared to burning wood is the absence of water and other components. This allows charcoal to burn at higher temperatures, and give off very little smoke (regular wood can release a significant amount of steam, organic volatiles, and unburnt carbon particles—soot—in its smoke, when it is not burned completely).

• Charcoal has been made by various methods. The traditional method in Britain used a clamp.[3] This is essentially a pile of wooden logs (e.g. seasoned oak) leaning in a circle against a chimney. The chimney consists of 4 wooden stakes held up by some rope. The logs are completely covered with soil and straw allowing no air to enter. It must be lit by introducing some burning fuel into the chimney; the logs burn very slowly and transform into charcoal in a period of 5 days' burning. If the soil covering gets torn or cracked by the fire, additional soil is placed on the cracks. Once the burn is complete, the chimney is plugged to prevent air from entering. The true art of this production method is in managing the sufficient generation of heat, by combusting part of the wood material, and its transfer to wood parts in the process of being carbonised. A strong disadvantage of this production method is the huge amount of emissions that are harmful to human health and the environment (emissions of unburnt methane).[4] As a result of the partial combustion of wood material, the efficiency of the traditional method is low.

• The properties of the charcoal produced depend on the material charred. The charring temperature is also important. Charcoal contains varying amounts of hydrogen and oxygen as well as ash and other impurities that, together with the structure, determine the properties. The approximate composition of charcoal for gunpowders is sometimes empirically described as C7H4O.[citation needed] To obtain a coal with high purity, source material should be free of non-volatile compounds.
