For this project, I was making six 4-ounce bars, so needed a total of 24 ounces of soap base. I used about 14 ounces of clear base and about 10 ounces of white base. I subdivided my essential oil into about that ratio, and added them to the soaps as I melted them.
The first soap we're going to use is the clear, so set the white base aside and melt the clear base in the microwave. Heat it in 30-45 second spurts...monitoring it so that it never gets too hot and boils. Stir gently in between the heating to help the chunks of soap melt.
