I'm certainly not the most experienced chandler here, and I don't know what wax you are using, but it looks like you have heavy frosting and sink holes.
Candlemaking can be frustrating as it is a try-and-see endeavor. And even more maddening, the fault doesn't always lie in the execution or technique. Candles have to be in a very happy place to come out nicely, which means there has to be communal love between the wax, the fragrance, the vessel and the wick. All of which requires... you guessed it... testing. Saving your good stuff for later will likely amount to a big ol pile of doodlysquat, as there are no guarantees if you get the cheap stuff to work well for you, that the expensive stuff will do so too.
If I were you (and I have been there), I would try the following:
- Pre-heat your vessel in a warm oven. I turn my oven on at the lowest setting for 10 minutes then turn it off. 10 minutes later I put my vessels in and let the sit while my wax melts. By the time I take them out they are not too hot to touch, but still quite warm.
- Apply your wick when you take the vessel out of the oven, not before... otherwise you can cook your wick... ask me how I know.
- Make a candle with your favored wax and fragrance, but reduce the fragrance to 8%. A lot of my woes were solved when I stopped trying to put 12% of FO in. My throw didn't suffer appreciably, and my candles looked much better.
- Pour your candle and then loosely wrap a tea towel around it while it sets out, loose as in close but not touching. My chandling area cools quickly, which I think attributes to sink holes. By giving your candle a little snuggy you can moderate the cooling rate. Too snug and the sink holes can be worse ironically. You don't want to insulate it, you just want to create a barrier to the cold so the cooling process is smooth and slow.
I do all my chandling at night, I live in a cold climate and my space has cathedral ceilings, so temperature management is paramount. These extra precautions have reduced my sinkholes to occasional nuisances, and I use 464, which is notorious.
Besides, it's fun putting the kids to bed with a snuggy binkie.
Lotsa luck!
