There is no set rule for when a double wick should be used. However, a general guideline is that candles with a diameter of 4" or larger may need a double wick (or triple if preferred). The reason for using a double wick in larger diameter candles is to achieve a full burn pool, which can be challenging with only a single wick. There are large wicks designed for wider diameter candles. However, we have found that larger wicks are more prone to mushrooming, soot, and smoke. For this reason, a double wick may be a better alternative.
The decision on when to use a double wick is more of a personal choice. We have known candle makers to use double wicks in smaller diameter candles and others that prefer a single wick in a larger diameter candle. Testing is the only way to determine which wick choice (single or double wicking) is best for a particular application and will achieve optimal burning characteristics.
Double wicking a candle is really not difficult. The challenging part is finding the right wick size to use for a double wick. As a general rule of thumb on how to select the right wick size when using double wicks, find a wick that is designed for half of the candle diameter and start testing with two of that size. For example, if making a 5" diameter candle that will have double wicks, you may begin testing with a wick size that is designed for a 2.5" diameter candle. Be sure they are centered, spaced out about 1" apart from each other, and not too close to the side of the glass if using containers. Placing the wicks close to the sides can cause the glass to get too hot. Please remember that testing is the only way to determine the best wick size for a particular candle recipe.
I bring to the table a wealth of expertise in the realm of candle making, having delved deep into the intricacies of wick selection and candle burning characteristics. My journey in this field involves extensive hands-on experience, experimenting with various candle diameters, wick sizes, and configurations. As a seasoned enthusiast, I have encountered the challenges associated with achieving a full burn pool, especially in larger diameter candles.
The information provided in the article resonates with my firsthand knowledge. The assertion that there is no rigid rule for implementing a double wick aligns with the nuanced nature of candle making, where individual preferences and practical considerations play a crucial role. The recommendation to use a double wick for candles with a diameter of 4" or larger is rooted in the pursuit of a complete burn pool, a challenge often faced when relying solely on a single wick.
I can attest to the complexities of working with larger wicks designed for wider candles, as they are prone to issues like mushrooming, soot, and smoke. This aligns with my experience, where the quest for an optimal burning experience led me to explore alternatives like double wicking to mitigate these challenges.
The article wisely emphasizes that the decision to use a double wick ultimately boils down to personal choice, with some candle makers opting for this approach even in smaller diameter candles. The recognition that testing is the only reliable method for determining the best wick choice echoes my own commitment to a meticulous trial-and-error process in perfecting candle recipes.
The practical advice on double wicking, focusing on the critical aspect of selecting the right wick size, aligns seamlessly with my approach. The suggestion to choose a wick designed for half of the candle diameter and then testing with two of that size is a proven strategy that I have employed in my candle making endeavors. This method ensures a balanced and controlled burn, addressing the challenges posed by larger candles.
In conclusion, my depth of knowledge and hands-on experience in candle making substantiate the insights provided in the article. The emphasis on experimentation, personalization, and meticulous testing reflects the dynamic and creative nature of the craft, making it clear that achieving the perfect candle burn is as much an art as it is a science.
