Decided to make some more, and this time I poured a plain slab instead of colored and scented soaps. It's 1 1/2 inches thick, and based on previous experience the transparency should increase over a few days or a week. It cut quite nicely with my utility knife, and the second photo shows a 1/2 inch slice. Then I made something sparkly with it at http://www.soapmakingforum.com/showthread.php?t=59472
