Wax melts are a form of wick-less wax that come in a variety of fragrances. The waxes are melted on the dish of a burner. The burner heats and melts the solid block of wax releasing the wonderful fragrances trapped inside the wax. The more the wax melts, the more it fills up space with aroma. Wax Melts are also known as wax tarts and wax cubes.
