Compared to pottery clay, terracotta clay, tile clay, fuller's earth and china clay, the history of bentonite is very recent.
The name bentonite was popularized by an American geologist after he found the clay in Benton Formation in Rock Creek area of Wyoming in 1888.
For example, clay shales and flint clays are harder than bentonite, china clay, etc.
In case of lignitic bentonite, however, its value is much higher because of loss of both water and carbon.
