C3 Naturewax Candle Blend 10 lb Bag NatureWax C-3 Container Wax is a 100% natural soy-based wax. Excellent for hand pouring, and can also be used on an automated line. Ability to rip wicks and re-melt tops, however not necessary as there is minimal sink upon cooling. Offers complete glass adhesion. No fat bloom when properly cooled. Excellent cold and hot throw. C-3 is compatible with most fragrances, even those not specifically formulated for soy waxes.
