Help! I got my first starter set from Amazon to make soy wax candles. I’m following the instructions and temperatures, but can’t seem to get a smooth top I’m getting a lot of craters. I smoothed some out with a hair dryer to fill the holes (didn’t have a heat gun), but once lit they cratered again. I also tried experimenting with black liquid candle dye in one of them and not only did it crater, but looks like some sort of sugar crystals on top and dried to more of a grey (I put 8 drops in)lol. I have watched and read a bunch on do’s and don’ts but can’t seem to get it right. I did end up buying some better quality materials to use but I really want to get the technique right before I use them!
