All of our candles are all natural 100% soy wax. Not only are there “green” advantages to choosing soy wax over a different type of candle wax, but soy wax also burns slower than paraffin wax, meaning you get a candle that lasts longer. While all candles emit some black soot while burning, candles made from soy wax burns cleaner and results in less soot. Well for holding onto the scent from essential oils, which are often used to scent candles. Because they burn more slowly, the scent is gradually released; there won't be an immediate wave of strong scent. This creates a more pleasant atmosphere.
