Place the heart fondant, light a tealight in the lower part of the incense burner and enjoy the delicate scents of our master perfumer (Grasse fragrances) as well as the benefits of natural stones. You can reuse this fondant several times and when all the fragrance has been fully diffused, the melted wax will no longer give off an odor. Once the wax has cooled, scrape it off with a spatula or a teaspoon, very gently so as not to damage the cup of your burner! Then you can throw the natural wax in the trash, it is biodegradable!
