I made my first hot process and failed to line it, because I was afraid the glopping down 2 feet of tube (way way too big) would bend the liner and defeat the purpose, and I didn't have mineral oil. Now it seems to be permanently stuck lol I do have it in my deep freeze, after an hour saw a tiny sliver of a gap so I thought woohoo and tried pushing and banging it loose on my porch but no luck. The soap itself is about 16 hours old. What is my window before its past cutting time? Any tips on getting it out of the mold now?
