The average specific gravity of china clay or kaolin is 2.25, and a gallon of bolted or pulverized dry clay packed will not weigh over 6 1/2 to 6 3/4 pounds. It requires 30 pounds, or nearly 4 gallons of linseed oil to mix 70 pounds dry china clay to a stiff paste, while 55 pounds of oil and 45 pounds of clay will be about the right consistency ...
China Clay, which falls under the Kaolinite group of clays is formed by weathering or hydrothermal alteration of felspathic rocks. It has the general formula Al 2,(Si 2 O 5)(OH) 4. It is a hydrated alumino-silicate having sheet structure. Free Silica (grit) is the most undesirable impurity and is removed during processing by levigation ...
