My very first experience with "cracked soap" after 20 yrs of soap making! I read several posts on the topic and think it may be the "over heated" problem. I would, however, welcome your feedback. I made a recipe according to my soap calculator, but with the following changes: I used 1/2 coconut milk and 1/2 water amount, superfatted about 1-2 oz Bakers Chocolate; insulated, and saw crack in the morning. Now, I'm thinking "don't insulate"! What think? I was able to slice the soap and pretty much press the cracks out and it looks great imo, so I'm very thankful for that. I'm posting a couple photos, hope you can see the cracks regardless of dark color. Soap is very chocolaty and so yummy smelling and looking, but hard to view the cracks.
