I have experimented with this series in soy wax and found that the CSN 16 performs well in scented, dyed, soy container candles 2”-2 1/4” in diameter. I’ve found that the CSN 14s work well within this range too, but the 16s are efficient for darker colored candles that require more (liquid) dye. They burn hotter than the 14s, but not to the point where I’m concerned about the container being hot enough to break or burn skin. The longer these burn, the hotter the container will get. I don’t hunk I’ve burned these longer than 4-4.5 hours at a time.I have not tried these on frangrance loads 9%>, but I imagine that they could handle heavier loads.
These wicks can soot and mushroom occasionally, so be mindful to trim them and keep the melt pool clean. CSN 16s have a thick wax coating and are fairly rigid cotton wicks. They work well with wick metal wick bars, but can be a little cumbersome in bow tie clips due to their diameter. I have noted unsatisfactory performance with the CSN 16 in a 4 ounce Candle Science tin using plain GB444 soy wax; I didn’t quite get a full melt pool. In fact, this review is specific to my experience using this particular wax.
