All of the soaps I have made for this master batch are milled, which means the original soap was cooked, cooled and cut, grated, and let to rest, then remelted with additional liquid and other ingredients, then molded to create bars of soap. The bars must cure for an additional 8 weeks or more, the longer the better, since the water will evaporate, leaving a superior bar of hard soap. The master batch was the batch I made last week that separated in the oven during the cold process/oven process. I quickly had to get the soap out of the molds, as it was leaking oil from separating and literally cook it and stir by hand, after burning out not one, but two hand blenders. It took almost three hours from start to finish and made a wonderful gentle lotion like soap. Milk soaps are known for the mild exfoliating qualities that leave the skin feeling smooth and silky. The base of these bars was milk and lard with castor and Meadowfoam oils. After Christmas, another master batch of a different formulation will be created and then the soaps will be milled from the original soap, just as these were. See, soapmaking is so mcuh fun!
