Compare Clays

Compare clays

There are many different types of clay, each with variations in shapes, sizes and mineral composition. In fact, the mineral structure of a clay determines its specific properties.

There are seven clay mineral groups:

  • Kaolin
  • Illite
  • Smectite
  • Chlorite
  • Vermiculite
  • Mixed-layer (combination of five listed above)
  • Lath-form

Both our calcium bentonite and sodium bentonite clays are in the smectite clay group. This is important because smectite clays are the *only* clay group of the seven that both adsorbs and absorbs toxins and impurities. It is what makes smectite clay most desirable. The most familiar species of smectite clay is montmorillonite, which refers to the town in France where it was first identified.

About Earth's Natural Clay

Earth's Natural Clay's calcium bentonite green clay originates from Death Valley, California, where it is sun- dried for up to six months in temperatures that reach up to 134 degrees. Our sodium bentonite clay was formed from volcanic ash rich in trace minerals in Wyoming. Earth's Natural Clay's Drinking Powder is mined to a finer 325 screen mesh. The finer the mesh the better the milling process and in turn the better it hydrates when liquid is added. Earth's Natural Clay and our suppliers have gone to the expense of independent laboratory mineral analysis and microbial analysis on our clay for internal use sold on this website. These can be found by navigating to Clay Mineral Analysis page under Learn on the home page.

How To Distinguish Quality Clays

All clay deposits have different mineral structures. Some are naturally fine and pure. Some deposits are shallow and having been exposed to the environment, contaminated with toxins and other impurities. It is important to know your source and feel confident in your provider. Our pure calcium bentonite clay for internal use has been sun-dried in temperatures up to 134°. It has not been irradiated or washed with alcohol or otherwise treated. Such practices greatly diminish the effectiveness of the ionic properties of the clay. All Bentonites contain a percentage of minerals in addition to calcium as well as a percentage of sand and silt. The process of removing the sand and silt from the Bentonite takes time and adds to the cost, but it produces a higher quality product. A key differentiator among sellers of clay is whether or not they have their clay tested, to ensure it meets quality standards. If a vendor has gone to the expense and effort to have an independent laboratory test, you can rest easily that their products are of high quality.

Calcium Bentonite vs. Sodium Bentonite Clay

Visit our Frequently Asked Questions page to learn about the key differences between these two types of clay. Our Drinking Powder is calcium bentonite clay. Animin is our best-selling pet product and our Worm Away is made with our food-grade calcium bentonite clay. All of our Therapeutic Muds are made with our food-grade calcium bentonite clay. Our Bath Clay is a non-food grade sodium bentonite clay and is for external use only.
