I can't remember who posted the method (someone either on here or on the dish, I'm positive), but I've followed it and it's gone fairly well (no damage to liners so far): freezer for no more than 2 hours, just to keep gel down during the period it heats up the most, then into the fridge for for the rest of the set up time. Still get partial gel sometimes because I use 100% coconut milk and some FOs just heat it up too much, but it's less than I was getting before.
Lyn, your advice to let the soap come back to room temp before cutting has helped immensely to avoid crumbling when cutting too! =)
**edit: I would imagine putting the molds in the freezer prior to pouring would be fine, since having them in there after pour for a bit hasn't hurt them... have wanted to try that since soapbuddy suggested it on another post, so will give it a go with ya Lyn ^^
