Ultra Core wicks' knitted fiber construction allows for increased capillary flow, which basically means that they make it easier for the fuel (the wax and the fragrance) to flow into the wick and burn off. This is how it should work, so you get a candle with excellent scent throw and a proper melt pool without any tunneling.
Ultra Core wicks can be used with virtually any wax. However, as with any wick, you'll need to perform wick tests to find the ideal wax, oil and wick combination.
Using Ultra Core wicks in low melt point waxes (like coconut)? You may want to try sizing down since the wicks burn hotter.
Using Ultra Core wicks with harder waxes (like beeswax)? You may need to wick up.
We're sure you're going to love these wicks!
