I am doing this for my first time, and I am using only parrafin wax, nothing else. It said that the the melting point is 150, but I melt my wax to 190. I am using making hurricanes, not regular pillars. I have never cleaned my mold, maybe that is also my problem. I would only leave it in the fridge for maybe 5 minutes and it would have a crack down the picture, or on the other side of the picture. I am learning as I go along. I should have made these a long time ago, then I wouldn't be so crunched for time. I am also trying to find something practical that I can find at the local Wal Mart or dollar store to put in the bottom of the hurricanes, so the tealight doesn't melt the wax. I have researched a little on here and found that a lot of people suggests cork coasters or disks. I was thinking maybe bristol board, but I think that could be a potential fire hazard.. not sure. I am from Ontario, so I don't have the same selection that the US residents do. I will keep my eye open, though. I will find something eventually. Thank you to everyone who has helped me. I will take some pics and show them when I am done.
