Charcoal disks allow you to burn any dried herb, resin, or incense powder with ease. Simply place the disk in a heatproof dish or bowl, light with a lighter until the disk sparks (30 seconds or so) and then put a pinch of herbs, resin, or powder on top. The charcoal has a long and even burn time at an extremely high temperature so it is very important to use a suitable heat-proof surface or purpose made incense burne
