Finding the perfect wick for a blend of two very different waxes like soy and paraffin can sometimes be tricky. Paraffin waxes typically are easy to burn and we usually recommend our LX wick series. However, soy waxes tend to require larger wicks and usually need a core like our Eco or CD wicks. We tested all three of the wick series to see what would burn best in this blend.
The Eco wicks produced large flames and tunneled quite a bit before forming a full melt pool. While the flames were within an acceptable height (no more than 1.5”), the amount of tunneling seen before a full melt pool forming could be problematic if the initial burn terminates before the full melt pool has formed.
The CD wick series has been a reliable option for almost every wax we have tested it in. The disadvantage of the CD wick is it often forms large carbon balls, or mushrooms, even when the proper size is used for the container. Small diameter containers (less than 3”) did tend to have less mushrooming compared to larger diameter containers.
The LX series also produced good results with forming a good melt pool and maintaining a good flame. As we saw with the CD wick series, the LX also had some mushrooming in larger containers.
For larger containers we found that a single wick did not burn nicely, often producing large flames (2+ inches), large mushrooms, and smoking. For containers over 3.3” diameter we found that using 2 wicks gave much better burn qualities, including even melt pools, 1” flame heights, and minimal mushrooming.
