Actually with chocolate its to encourage the crystalline structure due to the milk fats added in....there are numerous studies on polymorphic transitioning in chocolate, I suggest you run a google search and read the abstracts. And I'll say it again, wax is not chocolate. Consistantly drawing the parallel between soy wax and chocolate is like comparing apples to oranges. They may both be polymorphic but since that is a general term that has various meanings depending on what science you are discussing suffice to say; veggie oils are not the same. Even soy wax is not a solid soy oil since it is blended with other oils to keep it stable (like cottonseed oil). Constant heating/cooling the wax is part of the candle making process for those of us that melt more than a single batch at a time. Doing it deliberately for 1 batch is a waste of time when you aren't heating it to a high temperature in the first place (high temp being relative to what manufacturers do and what we do). And since soy generally speaking has a lower pouring temp than paraffin or beeswax, why heat your wax so high in the first place? If you pour between 100-140 F why in the world would you heat to beyond 180? It doesn't take 20 odd miutes to add FO, dye and pour. Especially container candles. IMO and to answer the orginal question: constant heating and cooling happens especially in a turkey fryer. If you want to call it tempering and keep a chart as to how many times the wax has melted, that's up to you. But I like streamlined processes and when I pour its to produce an entire line not a single batch. I personally don't have the time to play around and treat my wax with kidd gloves. If I have to fiddle with wax like Stella is suggesting, I ditch it because I'd never get anything done and I don't have the money to waste if the wax has been "tempered" too many times.
