The fast-burning charcoal is not one kind of the whole piece of charcoal fast-burning. On one hand, no need to do that; on the other hand, the production cost is higher and there will be little profit for shisha charcoal owners.
To make pellets the wood or other raw material is reduced to small pieces like sawdust. This material is then pressed into a funnel shaped hole called a die. As the material is forced deeper into the die it compresses as the diameter of the die gets smaller. This compresses the material into a dense pellet.
