As an alternative to burning it over smoldering charcoal – this is what I use, ( for times when I don’t have an cauldron or another incense holder that is safe for that sort). Instead of burning the incense, I fill a small saucepan with water, boil the water until steaming, and then place a teaspoon or two of the powder incense into the water and stir. Then I let it continue to steam on the heat for a few minutes, and let the incense scent rise with the steam. When the water boils or begins to, turn off your stove.
*NOTE: You can let let it sit on the hot burner and steam up till it cools. Also, the liquid mix afterwards can then be placed in jars, or a small bowl or cup, and used as an offering on your altar or elsewhere. (Just dispose of it after a few days )
SIDE NOTE: You can also seal the bottle/jar with wax, to make it a longer lasting offering – or make spell jars this way with the water/incense.
