Our Natural Soy Wax Candles are always in demand because they are fragrant and produce 95% less smoke and soot than paraffin candles. Soy Wax is a 100% vegetable by-product, not a petroleum by-product. Soy is a renewable resource grown on American soil and supports our nation's economy and farmers. Soy is non-toxic, non-carcinogenic and burns 30 - 50% longer and cooler than paraffin. It cleans up easily with warm water and soap and is easier on those suffering from allergies and asthma. Our 16 ounce Mason Jar Candles contain a minimum of 12 ounces of scented soy wax. We only use cotton wicks.
