I buy bayberry wax. The last carton was from S&P. It's not always available, and is ghastly expensive. The min is something like 25 kilos, with freight equalling the wax cost. There is a specialty market for it, but you really need to search for it. Not many people will pay what true bayberry is worth since they have no idea what it is or how precious. Beeswax definitely improves it. As Chris noted, it is super brittle. I have been melt casting tapers, losing one candle out of every 4-5 cast to sticking, even with loads of release spray. In the same carton i have had chunks that are yellowish to dark green, it all burns a wee little bit different. You have to test just like every other wax. IMO it is not the best choice for containers. It burns much like beeswax (similar temps), which is hotter than container waxes. It sure is a treat to work with though. Beings me right back to my NE roots.
