Basically I have a Copper incense burner and little charcoal pieces. I put an inch of sand in the burner and then whenever you want to do the incense I'll light the charcoal, put it on the sand (if you put the charcoal directly on the copper it will heat it up hardcore and youlld burn your hand if you touch it or burn whatever the burner is standing on), and then put various incense resins, woods, or blends on the charcoal which will burn and create the smoke. I burn frankencense, cedar resin, a combination of frankencense and myrrh, scented sandalwood, and I've also tried Oudh and other ones too. I've also noticed a few packs of Japanese charcoal I've bought have been far superior to the kings ones and general puck shaped ones due to having less chemicals, burnt charcoal smell, and mess. I have also read that frankencense has mild narcotic effects which wouldn't surprise me although it's extremely subtle if true.
