I found just popping it into the freezer for a few minutes works- it pops right out. I'm saving my leftover wax to make firestarters (yes, in all my free time!, but I hate to have it go to waste). I've been using Suzy's suggestion of the ecosoya PB/excel blend- so far testing has been very good, love it! I've been pouring into portion cups, not using dye, just keeping them white. I just poured a bunch over the holiday, so now have to wait for them to cure (the hard part!). Good luck on your testing, let us know how it goes! I also had all those same questions you did, as I had not made melts, and I haven't ever bought one of the Sc**tsy melts or warmers- so I haven't had experience with them either. Have fun!
