Now other chandlers may disagree with me here. That is their American/Canadian right. LOL But I really don't stress out over carbon beads / mushrooms on my candles. Combustion happens. There is no such thing as a perfect candle, in my book, because burning conditions vary greatly among customers. I test burn in fairly controlled conditions -- wick trimmed, no draft, no extinguishing until a full melt pool is achieved, etc. And I don't get a ton of mushrooms. But sometimes customers ignore good burning tips, so they are going to get soot, major shrooms, tunneling, etc. So I go for a good scent throw and a good melt pool. You could try cutting back on the spicy scent load and see if that helps. But if your wax is 100% soy, you probably aren't going to get great HT. Spices are funky that way in the soy waxes I've tested. ETA: Especially cinnamons. And when I say I get an occasional bead, I'm not talking the size of a ping pong ball. LOL I *would* take exception to that. Mine are fairly small. Maybe you can post a pic so I can get an idea of what you mean... because personal definitions of "excessive" might vary too.
