Tranquility Soy Wax Melts release up to 10 hours of frankincense, sandalwood and geranium per block and are the perfect companions to the Ceramic Burner available in Gifts/Home at Stella. Drop a block into the hollow of a burner, place a tea light in the burner and light it. The block will melt and release the aroma. Once the tea light is out, the oil will return to solid, and when the wax is cool, but not yet solid, it can be used as a moisturizer for your hands & feet! NOTE: Wax is HOT while burning!
