Sweet Grass Farms Soy Candle - White Lilac. If you haven't tried pure soy wax, you are in for a treat. Unlike paraffin candles, (which are made from petroleum), pure soy wax candles come direct from soy beans. They burn much longer than paraffin. They burn much, much cleaner than paraffin--leaving no black soot on your walls. It has been found that paraffin candles emit toxins that are unhealthy to breathe. What a nice alternative is soy. And don't forget those struggling farmers--you are supporting a new market for their toil.
