With that much coconut oil and salt, it should be ready to un-mold in just a few hours. If you have to cut it, you need to watch it and cut as soon as you can. If you wait too long it will be brittle when you cut.
I would start a new topic in The Photo Gallery. Unless something goes south, and then I would start a new post in the beginners forum with pictures and questions.
I used a six cavity mold so I wouldn't have to cut (I have a tendency to get sidetracked and forget), do I still need to unmold in a few hours if it's ready or should it be ok to wait until tomorrow?
