Can anyone help, I use Kerasoy 4130 soy container wax and poured vibrant coloured wax into containers. Around 80% of the time, the candles frost on top. I usually pour the wax at around 60'c, is this right? Can anyone make suggestions as to why it's frosting? I've tried, heating the containers up first with hot water under neath but nothing seems to make a difference. Also, could someone explain to me why it's pillar wax which you need to use to make soy candles as appose to container wax thanks
