One more thing I did with this... in one batch there was just a little bit of soap left. It was just enough to fill the bottom about 1/8" - 1/4". So, before the cleaning, I cooled the pot down. This let the soap on the bottom harden a bit. I pulled it up (came up very easily) and used cookie cutters to cut shapes from it. This worked really well because it was a fairly large surface. I'm sure I could have also made some curly Q's if I had thought about it. Once I peeled it up, I did the cleaning with the water.
