Soy Wax is fast gaining popularity. Soy is a clean-burning natural wax which may be used without additives necessary for changing the color, hardness, or clarity. Unlike paraffin wax, soy wax has natural oils that mix well with fragrant oils. Therefore, soy wax holds scent better than paraffin wax and shrinks very little during the candle making process. Soy wax is nontoxic and produces measurably less soot than other waxes, when burned correctly. Soy is a completely natural and renewable resource and helps support the American farmer.
