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. ## Features - HIGH FIRE: With a firing range of Cone 6-7 (1200ºC to 1240ºC), this porcelain clay is the perfect choice for potters seeking a stable and secure formula. - HIGHLY VERSATILE: This beautiful cobalt blue ceramic clay is valued for its smoothness, plasticity, stability and consistency.
