I don't have my recipe up here in my office (don't wanna wake up the baby and go fumbling for it:tiptoe: ) I think I found it somewhere through The Chemistry store Website. Something like baking soda, glyceryn liquid, & laurel somethin? It sounds like they are moldable for a while before they harden and you can put them in a soap loaf mold and actually slice them. At least that's what it sounds like to me. I hope thats how it works cuz it sounds pretty cool!
