A good soapmaker friend specializes in HP. She has a series of crock pots in which She heats her oils to 160, adds the lye solution, and cooks for only about 10 minutes before pouring off to a non-heated container for scenting, coloring and molding. As the crock empties, she adds the next set of oils. Repeat. She churns out 100 or so logs a day this way. SAP is always complete by the next day when the soap is fully cooled. No need for pheno tests.... Doing this would almost be like half HP/CP. Makes sense. I would imagine that you make sure and insulate the mold? I'm going to give it a try. Looks like The hubby is gonna have start building me some molds. I'm saving everything around here that looks anything like a mold and it's driving everyone crazy. Now their try to sneak behind me and throw stuff away.
