I made some plain, unscented soap yesterday. We were down to our last bar and I had to make some quickly so I used the hot-processed method. I made it in the crock pot which took about an hour from start to finish; it was ready to use this morning. I used soybean oil and olive oil as the main oils and a couple of ounces of castor oil. The result was a lovely hard bar with lots of creamy, lathery bubbles.
