The 44-B clay is similar to 54-S and is a recommended selection where additional plasticity and strength are important. It is particularly recommended in extruded and plastic processed ceramic formulas such as electrical porcelain and tableware. The 44-B can also be used in monoporosa and monocuttura tile bodies for additional press density and strength especially for a large dimension shapes.

Warning: This clay product contains quartz which may cause delayed respiratory disease (silicosis) if inhaled over a prolonged period of time. Avoid breathing dust. Use NIOSH/MSHA approved respirators where TLV for crystalline quartz is exceeded. IARC Monograph Volume 68, 1997 concludes that the respirable fraction of crystalline quartz, causes cancer in humans.
