Bentonite has many different qualities. It is the most absorbent mineral found in nature. Because of its expandable quality, several teaspoons full will soak up a glass of water. Its “slippery when wet” property has even caused a few auto crashes when accidentally spilled on roadways.
After processing, this volcanic dust forms a gelatin-like substance that, when wet, is easy to mold. When dry, it resists the passage of water. And because it is non-poisonous, odorless, and tasteless, it serves other varied uses too. We probably use it a half dozen times every day, without knowing it.
