I generally end up with lots of shavings from soaps, when I clean them up to label them, little slices off the ends that are too thin to make into samples and just bits and pieces of soap that I stick into a large clean baking soda bucket. I figured it was getting pretty full and heavey so i decided to dump it into the crock pot and see what comes of it. I plan on letting it cook down for at least 8-10 hours, this is a bit of an experiment for me, all of the soap shavings were still very fragrant and some where very colorful, there are a few browns, many pinks, some green, yellow, orange and a tiny bit of natural color. Im hoping I can cook off much of the fragrance oil, I havent decided how to scent this handmilled batch yet. Im going to wait and see how it looks once its cooked down to determine the scent.
