I was wondering what makes a candle wrinkle on top. I poured a heart shaped candle and this morning when I got up it had all kinds of wrinkles on top. I did a search and only found the problem with soy wax. I used Yaley glass fill wax with Red Hot Cinnamon and pured at around 160. I did take the heat gun to it and it seems like it helped but I have not had this problem before so I was just wondering if it was something I did wrong or was it just a fluke. I hope I gave you enough info. Remember I am still stupid at this.
