Wicking is never an easy task, and this wax was no different. We found this wax to be a little trickier to find the right wick than we expected. Not to worry, we did all the experimental testing so you don’t have to!
We tested our CD, Eco, and LX wick series.
- The CD seemed to perform well in the smaller diameters and did ok with the widest containers when using multiple wicks.
- The LX also performed well in the smaller sizes and the widest diameters.
- The Eco did well in the mid-range diameters where the CD and LX seemed to struggle to get full melt pools.
We continued testing the CD and LX to find great options for you. Because the Eco is limited in the sizing, we found that they only worked in containers between 2.5” to 3” in diameter. Due to this strange anomaly, our wick guide has our recommendations for the best wick size for the diameter range, even if it isn’t in the same series as all the other diameters.
The most difficult part of finding the right wick size is not only getting a full melt pool, but also leaving the sides of the container as clean as possible. Many test candles had perfect melt pools, but still had a lot of wax left on the sides. Normally the solution would be to go up a wick size in the series. In many cases this worked just fine. However it did reduce the overall burn time significantly. Several times we found that going up a wick size made it tunnel. While it can be a rare occurrence in general, it’s worth noting here so you don’t go in the wrong direction during your testing.
CandleScience typically does not recommend multi-wicking containers unless they are over 3.5” in diameter. We found that for our Extra Large grouping in the wick guide, a single wick was just not going to get a good clean burn. We do have recommendations to double wick these size containers (3.3” - 3.79”). The single wick sizing ended up producing very large flames, significant mushrooming, and an incomplete melt pool. We think you’ll be much happier with the results than when using a single wick.
More surprising to us, was our test results in our Large grouping in the wick guide. This is where our most popular containers, like the Straight Sided Tumblers and 8 oz. Candle Tins, fall.
We’ve always discouraged using multiple wicks in these diameter containers for concerns over safety. The diameter usually is not wide enough to allow adequate spacing between the wicks and the edge of the glass. The placement can be tricky for well seasoned candle makers, and we want to make sure new candle makers are making safe candles and using proper wick sizes.
We tested 15 different single wick sizes across multiple series and discovered that to get a full melt pool, there would be very large flames, sometimes 2.5” in height. It also came with excessive mushrooming and a thick wall of wax left on the sides of the containers. This is when we decided that double wick testing was a necessity. We started with the smallest wicks possible in the LX and CD series. We found the LX performed very well and maintained small, tight flames while producing a full melt pool and a great hot throw. The CD did alright, but the flame heights were a little taller and sometimes flickered into the glass; this is why we recommended only the LX double wicked in this group in our wick guide.
This was noteworthy from our testing results, but we found that the better the melt pool, (meaning it was ½”-¾” deep and extended edge to edge of the container) the less pitted and bumpy the wax set up after the wicks were extinguished. When we had shallow, incomplete melt pools the wax set up more pitted and in some cases with bubbles around the edges. This doesn’t necessarily mean you can control the look of reset wax by the wick choice but it may show that testing a larger (or smaller) wick may be worth the added time if you have concerns about the look of your burned candles. We like the rustic look of natural wax candles and we encourage you to embrace it also. This shows it is truly a natural wax with just enough additives to make the candle perform well without obsessing over the aesthetics during use!
