Your side of the world must be totally different than my side Stella, because I properly clean my containers too and still get wet spots. However, wet spots don't bother me. Just about every single candle I see on store shelves has wet spots. What does bother me are the other side effects working with soy can cause. I will say, I read on this site about "tempering" - tried it - liked it. Now I just let the wax sit for a couple of hours, then re-heat till it looks good, and pour into my clean containers. I cover with a box insulated with additional cardboard and cover with a thick towel. Tops come out flat and pretty. Still get wet spots, but no matter. Of course, that all changes once it's burned. I've had one test candle change colors on me similiar to the ones you had littlebrownbug. But mine was a 70% LP415 and 30% J223 mix, in a 4" diameter jar, double wicked with CDN 8's, scented with butter cream and dyed a pale yellow. Great melt pool, no sooting on jar or from wicks when burning. But when the melt pool set up, the wax was grey. It was the first time I had tested a CDN - wondered if it could have been the coating. But haven't tried making another candle with that combo again, so really couldn't say. The meltpool sets up grey with every burn. However, I have used CDN's single wicked in smaller jars, same wax, dye, FO, and no change in color like those. I'll probably need to try the same candle and see if it does it again. And if yes, try different FO's and colors. :rolleyes2
