When making soap it’s important to have a quality soap mold. It’s the best way to easily shape and cut your soap into cubes and bars. However, it can tricky to calculate the amount of soap you need to fill your soap mold without being too short and without overflowing it.

First, when you get your soap mold, measure the amount of space in your mold by cubic inches. Next, take that volume figure and multiply it by .40 to determine the amount of oils needed in the recipe. Enter that amount into a lye calculator and you’ll know how much soap you’ll need to fill up that mold efficiently.
