What is volcanic ash clay?
Many years ago, a chain of volcanoes stretched from Mexico to southern Canada. Their powerful eruptions produced tiny cinders and dust-sized particles that billowed high into the sky and were carried eastward by the wind. As this volcanic “ash” descended back to the Earth, it settled into the Mowry Sea, a shallow, stagnant body of water which once occupied the central United States. There, the minerals in the volcanic ash reacted with elements of the salt water, forming a substance known as montmorillonite. Montmorillonite is commonly known today as Sodium Bentonite Clay.
