This handy lye calculator will help you figure out how much lye (NaOH) to add to your soap recipe.
Simply enter the amount (by weight) of each oil you are using, select your superfatting level and click
"calculate". For complete instructions and safety tips on making soap we recommend our How to Make CP Soap DVD or
the Soapmaker's Companion.
