PACKAGE OF 10 - Charcoal discs are suitable to be used with Our range of Incense and for the burning of Herbs, Gums and Resins. Place a self-igniting charcoal disc on a fire-proof surface, away from flammable objects and light it. Be aware that these discs may occasionally sparkle profusely upon ignition. Allow sufficient air to flow around the charcoal to ensure burning. Some people prefer to open the window whilst it is igniting as it gives off smoke. Once the charcoal disc has finished sparkling it will start to glow, usually first on one side, slowly spreading over the whole disc. When the entire disc is glowing red hot it is ready for adding the incense. Keep incense and charcoal out of reach of children. Exercise due caution when igniting your charcoal disc and also when discarding of used ashes.
