A friend found this and sent me the link, asking if it was anything that could be used to make soap molds, and I dunno the answer to that. I'd think that it would be fine, as it's supposed to be fine up to 400F, but I wanted to see what the more knowledgeable people thought. It's definitely a neat idea, could make some really interesting molds using different rubber stamps and the like. Here's the link:
