Small portions of Quest Premium Bentonites and hectorite clays are used to supplement other clays, and will create considerable improvement in the properties of ceramic bodies.
The extremely large surface area of hectorite - as much as twenty to forty times as much as other colloidal clay substances - allows for a much greater number of contact points between the larger grains of the aggregate and impart better mobility or higher bond strength to the mass, particularly in aluminous porcelains and technical ceramics.
Hectorites are non-migratory binders that impart uniformity in ceramic bodies and fire to a white finish.
The excellent suspending and plasticizing properties of hectorite, together with its ability to fire white, is an excellent alternative to the customary clay additives in enamel formulations.
The high suspending power eliminated fish scaling due to lack of suspension and gives greater film strength to the enamel.
