Box of 100 charcoal discs commonly used for burning resins, powdered herbal blends and loose incense. The disc should be placed in a fireproof bowl before lighting (our mini cast iron cauldrons are ideal for this), let the charcoal disc heat up - much like as you would with a BBQ, before sprinkling incense, resin or fragranced powder over it. Packaged in rolls of ten discs.
