This is 50 yards of cotton core wicking size 28-24C. This wicking is from a spool of Atkin&Pearce wick. Cotton Core is a high performance cotton wick designed for pillars, containers and some tapers. Specifically, I've used it in taper molds doubled and twisted together to make a single wick. It is designed to provide proper burning for beeswax candles. It is a specialized braided construction to provide increased rigidity in the molten wax pool as it burns. 100% cotton - normally used for small pillars 1-15 inch in diameter, some container candles and some tapers. I advise testing using your wax mixture and mold design as the uses are suggestions only based on our pouring experiences!
