The Nova Studio over the years and I would like to venture out on this process in the near future. So you can say that I have purchased a lot of soap making supplies and equipment. Some of the equipment I have purchased have been molds including silicone bake ware that I want to use for soap batches, but I was in a quandary on how much soap to make for a particular mold especially if it originally was intending for baking. So I looked online and found an article written by David Fisher called How to Calculate the Size/Amount of Soap to Fill a Soap Mold. This article covers every shape you can think of of. So if you are mathematically challenged then this article is for you.
