Bentonite and gypsum are materials formed by geologic properties. Bentonite is classified as a clay (because of its small grain size), and gypsum as a mineral (because of its crystalline structure). Both bentonite and gypsum are used as ingredients in various commercial products.
Origins
Bentonite results from the modification of volcanic ash. Gypsum is formed by either the compression of sediments (sand, silt or clay), or water evaporation within sediments. Each of these processes occurs over millions of years.
Appearance
Gypsum has a jagged, crystal-like appearance. Its color ranges from clear to an opaque tan. Bentonite feels greasy and is initially light blue or green, but turns yellow or brown with age.
Location
Over 90 countries produce gypsum, including the United States, Canada and Spain. Similar to gypsum, bentonite is abundant and can be found all over the world.
Special Properties
Bentonite has the ability to absorb a large volume of water. Gypsum acts as a fire retardant because it contains trapped water molecules that are released as steam when heated.
Uses
Bentonite is used in a range of products including kitty litter, paper and detergents. Gypsum is used in drywall, plaster of Paris and cement.
