This sand is perfect for adding a protective and insulating heat-safe base to your cauldron or other vessels so you can burn all the things safely!
Place enough sand to create a centimetre or more thick layer on the bottom of any cauldron or fire-safe dish, light a charcoal disc and place it in the center of the sand. You can also use this as a sturdy base to stand up incense sticks or cones instead of a typical incense burner. This also applies to spell candles that may not fit in anything else.
