Charcoal is used to burn resin incense and herbs. Each roll of charcoal has 10 individual one time use disks. A charcoal disk is lit and placed in a fire safe burner or cauldron. Tongs should be used to handle charcoal as they become extremely hot. Once the charcoal is lit, bits of resin incense and/or herbs can be placed on top to burn. Furniture should always be protected with a coaster of some kind. Keep away from children or pets.
