First I want to say hello, this is my first post. I am working with C3 soy wax and keep having the same problem. I have been making candles for about 6 months now votive, container, and tarts. I have tried different temps for pouring and have also tryed to keep the room at a decent temp, around 72 degrees. I have poured at 160, 150, 130, 120, and 90. I have also tried additives like, vybar 260, vybar 103, universal additive, and translusent (i think is what it is called). I still end up with big holes in center of tarts and candles, or pulling away from glass. I have also noticed frosting when I dont use additive. Some have told me it is a one pour wax and other people have told me it needs a second pour. my containers are baby food jars and jelly jars. I have also poked holes and done the second pour. does anyone have any advice. to help get rid of sink holes (that look more like crates) and frosting. Why does the wax pull away from the glass? I redid one candle 6 times last night and after 4 hours of fighting with the wax,(the wax won)! i gave up!
