I'm new to candle making, & if I'd based my decision of which wax to use solely on what Candlescience says about 464, I'd have started with it too. They really push it to beginners, saying it has the best throw & is their "most consistent" soy wax & easy to use. I almost ordered it on the spot. I thank God that I kept Googling 464 & reading all the comments about the many problems chandlers have with it, especially the newbies. Now I plan to start with Ecosoya CB Excel for soy, & Glass Glow for palm. In fact, the palm seems much easier to work with than soy, & since I live in a hot humid area, I've decided not to start with soy, especially with Spring around the corner. So I guess the vets mostly don't use 464 because they know better.
