I use it constantly.
It's sold with ceramic/sculpting tools, and I do use it with my Precious Metal Clay (PMC) as you would in ceramics: score clay and use slip to join the pieces, etc.

I predict more birdies in my furture. I haven't painted really since 2002 and that time I was stuck on chickens. I don't really like birds as pets, but they are fun to paint.
