The molds work great. its a little hard to get them out, but with a few taps on the table
the candle slights out easily. I have all the 3 sizes of the candle mold
I would buy them again.

In order to have the candle slide out of the mold easily you should lightly put mineral oil on the inside of the mold. The addition of stearic acid (4 % by weight) helps the wax contract when cooled. The aluminum is soft compared to steel molds so you need to be careful and not scratch the inner walls.

Prior to using this mold, I had only ever made container candles, so I had no experience with molds/pillar candles. The first candle I made turned out PERFECTLY. The second candle I made was GORGEOUS! Every single one since then has surpassed my expectations! The process is easy and the result is so satisfying. High quality stuff you've got here, Candlescience! Thank you!

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.

My first time at making a pillar candle and I'm hooked! My first candle came out beautifully. I used a little mold release spray and it slid right out. I had zero leakage using Sculpey clay I already had. I put a little clear shipping tape over the clay, but I don't think it was necessary as I didn't see a drop of wax escape. I have now made 5 candles in 3 different batches. I had to repair 3 but the first and 5th candles came out perfectly. I heated the mold prior to pouring the last time and poured around 135 degrees. Maybe beginners luck, but I'm happy! Thanks Candle Science!
