Well isn't 112 clay used in many a studio? And aren't all those specks(112 BROWN CLAY (Cone 4-6)
Plastic clay for wheel and modeling. The addition of granular manganese gives a speckled surface. )
Manganese? Is this dangerous. I just started using 112 and there are a lot of specks and I fire in my basement with a window fan.
Am I being stupid??
