Increased stability of solids dispersed in a liquid by adding substances which form protective colloids.the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation. 
The dispersion of clay slip or glaze by the addition of an alkaline electrolyte e.g. sodium silicate, Dispex, etc.
Separating and dispersing the clay particles in a slip making it more fluid. Sodium Carbonate and Sodium Silicate are deflocculants, when disolved in the slip they allow large proportions of clay to remain fluid giving a high density to the slip.
a process of making casting slip where clay is made more fluid with the addition of sodium carbonate and sodium silicate.
