Angel Wing Candles are all natural soy candles CLEAN BURNING -- Soy wax is non-toxic and burns cleaner than paraffin, with no petrol-carbon soot which can blacken walls, ceilings, and furniture, contaminate ventilation ductwork in your home, as well as add toxic carcinogens into the air you breathe.. RENEWABLE RESOURCE -- Soybeans are a renewable source, unlike paraffin, which consists of petroleum. BIODEGRADABLE -- Since soybeans are vegetables, soy wax (basically made from hydrogenated soybean oil) is naturally biodegradable. Soy wax is also easier to remove from materials and other surfaces than paraffin wax. Also when you get through with my jars everything is reusable. The lables I use are dissovable, the wax washes out of the bottom and you can reuse the 4 oz jelly jar.
