Soap Bench

A calculator for bar soap and liquid soap. Choose the oils, a superfat, and the liquid, and it weighs the lye so a batch can be repeated.

The recipe library includes common starting batches. After you sign in you can change a recipe, save the ones that work, and keep notes and photos with them.
