Question: How can I calculate how much cold process soap a mold will hold?
Answer: Since oils used to make cold process soap are lighter than water we recommend using this formula to estimate the amount of cold process soap a mold will hold.
Mold Volume x .40 = Ounces Mold Holds
Step 1: Measure Mold and Multiply. (3.5" x 8" x 2.5" = 70)
Step 2: Convert Volume to Ounces. (70 x .40 = 28 ounces).
Note: 1 oz equals 30 grams
