What makes a clay plastic? I throw that question out to all you who care and have an opinion. I've been working all sorts of clays lately. Poking, prodding, scratching, sniffing, touching, tasting and handling; trying to determine what makes one really sing and another fall flat (quite literally). So......what say you? How do you characterize clay? How do you measure plasticity? What is the acid test?
Hi, thanks for the comment. Borosiliscate isn't something I'm familiar with at all. Will have to look it up. I've always used lead, it seems to do something that nothing else can do, but I'll look it up see what I can find out.
