Hexagonal briquettes are created from a block of material that is machine-printed to be a standard size out of leftover coconut shell charcoal combined with a small amount of wood charcoal. The charcoal is processed into briquettes in the appropriate form and size. Due to their high calorie content, which allows them to burn for an extended period of time while being highly effective, efficient, and inexpensively, these briquettes are typically used as fuel to start and keep a flame.
