Wow this is awesome.
How do people just know these things about different clays? I'm over here like, *points at twelve different kinds of clays*, "ooh that's a clay!"
It's really important to know when you want to make molds, since sulfur clays will ruin most silicones. I actually picked this clay because my favorite artist uses it. It doesn't contain sulfur tho so I really don't know what messed up the cure :(
woah great detail
