Bentonite is colloidal, it is typically finer than ball clay, can have huge surface area and active electrolytic which gives extremely high plasticity. Bentonite can produce ace dry strength without much effect on fired color. We design our product called TERRAWELL™ which is a typical light color Sodium Bentonite.
