Kentucky OM #4 supplies SiO2, Al2O3, TiO2, Fe2O3, and small amounts of several fluxes. OM #4 is a fine-grained ball clay with good plasticity and strength. It is very common in glaze recipes. It undergoes a sudden color shift around cone 8-9, from straw yellow to solid gray [IMC]. Contains 67% kaolinite, 19% free quartz, 7% feldspar, and 3% organic material. Manufactured by the Kentucky-Tennessee Clay Company; comes from western Kentucky.
