|Monthly Tech-Tip |
A highly-purified, synthetic colloidal smectite clay that imparts viscosity and suspension properties to glaze suspensions. It will form highly thixotropic, heat stable, clear gels when dispersed in water at a 2% solids level. It is easily dispersed without high shear mixing equipment and has a very high surface area. It provides synergistic viscosity and suspension properties when combined with various organic polymers. It is free of crystalline silica and low in transition metals and other impurities.

This is less viscosity modifying than CMC gum, Hectalite, Veegum and Mineral Colloid BP.
Gel White 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.
