Bentolite H is a white bentonite with a small particle size and high surface area and is popular in oil absorbing applications (e.g. medicated soap bars). It can act as a rheological aid in water based systems imparting thixotropic flow properties.
In glazes, when used in combination with carboxymethylcellulose, Bentolite provides for improved rheology, solids suspension, glaze adhesion, sprayability, and acceptance rates.
This is less viscosity modifying than CMC gum, Hectalite, Veegum and Mineral Colloid BP.
TB2 Data Sheet
Clays that are not kaolins, ball clays or bentonites. For example, stoneware clays are mixtures of all of the above plus quartz, feldspar, mica and other minerals. There are also many clays that have high plasticity like bentonite but are much different mineralogically.
