I decided to make my own pillar candles because they tend to be expensive and most commercially available candles are made of paraffin wax. I am soooo glad I decided to buy these molds. They were incredibly easy to use and the resulting candles were gorgeous.
A couple tips: Some wax can leak out of the bottom of the mold if your seal isn't tight. I put the molds on a cookie sheet, so the leaks weren't a big deal. After a few hours (or overnight) of letting the wax cool, put the molds in the freezer for a few minutes. The candles really pop right out.

I wish I could post a picture of how much I loved using all three molds: 3.5x3.5, 3.5x4.5, 3.5x6.5
They all performed excellent!
Tips: To remove easier...put in freezer for 5 minutes after they've set up overnight.
To clean molds without a spray, simply put in over for 10 minutes at 200 degrees and wipe out with a paper towel.

I made my first pillar but it was a challenge. The first time pouring turned out to be a disaster as I didn't seal the bottom well enough and the wax just went right into the pan the mold was sitting in. Phew, I was actually thinking. Hehehe... So another go round with a LOT more duct tape and success! A little wax still seeped out but nothing like the first time. I used IGI 4625 and did have to do a second pour to fill in the sink hole. After a few minutes in the freezer, it popped right now and was completely smooth. This will go to my first paying customer! Definitely going to look at some other options to help seal the wick hole but overall, the mold is excellent.

These are by far the best molds I have ever used. The bottom is concave so you have a wax well built into the top of the candle but you also have plenty of room for putty AND I use HVAC DUCT Tape (it is like aluminum foil) and never have leaks. The previous poster gave a one star because she didn't have putty. A novice mistake which has absolutely nothing to do with these molds. They are perfect - no seam - I don't clean them I just reuse them. They do not require silicone spray and my candles slide right out of these fabulous molds. Well worth the money! Will last years with heavy use. I love them and so do my customers who buy my candles.

My first attempt at making pillar candles and I formed the perfect pillars! I used these metal candle molds along with the wick pins.
I also used the Ecosoy for pillars, the liquid die and silicone spray.
I put a wick sticker on the bottom to cover the hole, dropped the wick pin in and sprayed it with silicone. I had no problem removing my candle once it was set.
