Charcoal discs are necessary for burning non-combustible incenses. Take one tablet and place in a heatproof stone dish. Do not hold the tablet in your hand while lighting it. Light the edge of the tablet with a match or a lighter. The tablet will then light across its surface. Once the tablet is glowing, small amounts of herbs or powdered resins can be placed on the tablet.
Store your Charcoal discs in an airtight bag or jar.
Make sure the charcoal is placed on something heat-proof, such as stone, as they have a tendency to shatter china and burn through combustables. Use only an incense burner or censer and take care to place somewhere out of children and animals reach. The immediate burn off should be done in a well ventilated area and not inhaled. Once the coal is white hot you can place your herbs or resins on top.
These coals are also often used for Shisha, also known as Hookah or Nargile.
In order to maintain freshness, opened rolls should be resealed and stored in a cool dry place. Effective storage will ensure quick lighting and a long burning time.
