Then, the energy scale method was used to analyze and discuss the results of the direct shear creep test. The discussion showed that 1) the average viscosity coefficient of kaolin was greater than that of bentonite, which decreased with an increase of kaolin and bentonite; 2) the thickness of adsorbed water or the double electric layer …

Kaolin mining has a long history in the U.S. Southeast. Before Europeans arrived, the Cherokee people used the white clay in their homes and in pottery. As early as 1767, an English potter negotiated a deal with the Cherokee Nation to ship five tons of Georgia clay back to the Wedgewood, a pottery company in England, for use in porcelain.

Water Absorption levels of popular clays: (Kaolinite) Kaolin Clay: 65%. (Illite) French Green Clay: 150-200%. Bentonite Clay: 300 – 700%. The higher the absorption level, the more moisture the clay takes out of your skin. Bentonite clay can absorb 300-700% of its mass in water, while Kaolin clay absorbs only 65%.
