  • What is Activated Clay? (with picture) - wiseGEEK

    Activated clay is clay, usually of bentonite origin, which has been treated to improve its ability to adsorb. The clay is processed with acid, upping the adsorption properties of the clay considerably. Once it has been treated, activated clay can also be reactivated as it is used, allowing people to reuse the clay rather than having to continually replace it.
