I unmolded my second pour from Monday and this is what my mold looks like. These molds are new. I've only used silicone and PVC pipe before this. It was a struggle getting the mold off the soap. It did not want to come off! (I'm thinking that right there must have been a clue.)
Yes, it needs greasing.
Did it gel? Ungelled soaps are sometimes pain to remove from molds.
I made some individual ones the other day, in silicone molds. They didn't gel and 3 days later corners were still stuck in molds. They are all wonky and misshapen but they are for personal use so who cares.
