CDN wicks are wonderful for all container wax blends, and are the preferred wick for our No. 7 Designer Natural Soy Wax Blend. Treated with a second mineral salt bath, CDN wicks tend to burn cooler than CD wicks in most waxes. CDN wicks curl to an approximate 30 degree angle, while CD wicks curl to a 90 degree angle. The lesser angle of the CDN wick tends to create a flame with a smaller base. These wicks are wonderful for nuanced wicking issues, allowing for a truly perfect burn.
