Four Methods of Making Soap
There are four basic methods for making soap at home:
Melt and Pour - melt pre-made blocks of soap and add your own fragrance
Cold Process - the most common - making soap from scratch with oils and lye
Hot Process - a variation of cold process where the soap is actually cooked in a crock pot or oven
Rebatching - grinding up bars of soap, adding milk or water, and re-blending them
