Soy Wax Candle Forum - Online resource for soy candle makers

I'm a 1st timer at candle making, have looked over this forum and taken into consideration everybody's tips. My candles are pulling away from the glasses and the free standing votives have a frosted apperance. I have warmed the containers, done everything else right as far as i know, i'm using Ecosoya CB-135 but thinking of changing to Ecosoya Advanced Container Blend as the description says it's designed to eliminate 'frosting', surface colour changing and imperfections on the surface of the candle.
Can i remelt the candles and repour them. If so, do i remelt to the same temp 80C (i'm an aussie lol) and pour at 50C. The fragrance and colour are good. I want to sell them and need them to look great lol.
Thanking you in advance for any help.
