Now, that is the truth. I've only had ash when my soap was uncovered. My very first batch of soap was made in a TOG mold (I started with the best) — it was the most beautiful, ash-free log of soap you've evah seen.
I am using individual molds for my soaps, 3 molds in a square and the ash gets on the bottom and after I remove it from my insulated box, the white ash will start to creep into the rest of the bar.
I am using the cp process and was wondering how to prevent the ash in individual molds. My wooden soap log mold works well but I am trying to make my soaps with pretty molds now.
No matter what molds of mine I use, if I cover the mold and give it time to properly set up before unmolding, I can avoid ash. If I don't cover my molds, it is a given that I will ash. I've had soaps that the ash actually enhanced the look of the soap.
