Review: Porcelain like clay. - This pretty blue porcelain is also possible to form into a box.
Review: 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.
