It ok
Mary Blue, and fires like a light blue it’s a lil chalky I mixed it with regular porcelain and it did great so I got a good combination out of using both of them but by itself it’s a little weird to throw with. I made a couple ocarinas with it and it turned out pretty cool.

Love this blue! Fires into a mellow light blue under low temp and fires into a bright deep blue under high fire. Gorgeous!

Beautiful color but a little hard to work with
This clay is a beautiful color both bisqued and when glazed. It also holds an impressed design well. But, the clay itself is a little difficult to work with. It does not respond at all like most low, mid, or high fire clays. I will buy it again in the future, though, because of the color.

Nice and pliable, doesn’t crack when item dry. The color may vary. I had to paintmine with acrylic paint to match the piece. Otherwise perfect for little projects
