Angela explained to me about the different oils and SAP value, and how each oil has a different SAP value. She explained that because of the difference in SAP value the amount of lye that you would be using will be different (of course if you stick to one recipe it will be the same). We went online to Soap Calculator, and printed out our recipe and how much lye we should use. I wanted to make Activated Charcoal Soap using Olive Oil, Palm Oil, and Coconut Oil. I prepared the oils under Angela’s guidance, and the lye solution. Angela then showed me how to split the soap batter, and I added activated charcoal to half the batter, and Angela showed me how to swirl the soap. Fantastic! Angela explained everything to me, from how to line the mold to how oils and lye makes soap. I would recommend Angela to anyone who wanted to learn how to make soap, she is a caring, kind, wonderful person, not to mention a GREAT teacher.
