I've made up several batches of palm pillars and votives and had zero trouble with sticking. I did use the palm stearic acid recommended - 1-3 tablespoonfuls per pound of wax. We used the minimum for the first batch and worked our way up to the maximum. We are not using purchased molds right now - using "found" molds like plastic containers, milk cartons, etc. Even the little glass flowerpots make nice molds (be SURE there is no "lip" that bulges inward on the rim of the glass, however, or the candle will hang in the mold). We do clean up the glass "molds" before repouring, but when the others get funky, into the trash they go! I don't NEED more stuff to wash... We, too, heat the molds and wipe them out with paper towels - works very well for soy and palm, although the container soy cleans up the easiest of everything we have tried thus far... I just got in some soy for pillars today - have not made any yet, but the votives I made earlier just dropped out in my hand! We love soy and palm wax - especially palm because of the interesting effects one can achieve with it. Not sure about candlemaking, but one should pay attention to the composition of the mold as well as the casting material when choosing release. Certain agents that work well for metal or abs plastic will eat latex alive, etc. Good luck - hope you're havin' fun!!
