Weighing much larger amounts of a soap recipes oils to create volume in one weighing therefore saving time.
If I multiply my soap recipe oils by 10 (54oz x 10 = 540 oz) it is called a master batch. I can save time for other things like cutting, wrapping, labelling and selling soap.

If you make a master batch you are increasing the amount of soap you can make in a day with less effort.
