This class will introduce you to the basics of making cold process soap. Cold process soaps are created by blending oils (or fat) with a lye mixture. In turn the soap saponifies over the next twenty-four hours turning the lye-oil mixture into a solid bar of soap! The class will cover the following: • Brief history and basic chemistry of soap making • Necessary materials, supplies and equipment • Safety considerations when working with sodium hydroxide • Taking accurate measurements & proper mixing temperatures • Coloring your soap (micas, herbs, spices & clays) • Scenting your soap (fragrance oils verses essential oils) • Preparing your molds and molding options • Insulating, cutting, curing and storing your finished soap This event is generously sponsored by the Friends of the Belmont Public Library.
