Suspension is the nature of power that allows a substance or a mixture remains in the form cairan.Sifat is highly related to the plasticity. To reduce the clay suspension is added flocculant is a substance that serves to accelerate the deposition of clay granules, namely: magnesium sulfate. Deflokulan: a power-enhancing agent dispersion (crystallize) so that the clay granules remain melayanglayang. Examples of deflokulan: waterglass / sodium silicate and sodium carbonate. Deflokulan commonly used to make clay slip for the formation of cast molding techniques.

Slaking properties
Slaking properties is the nature of the clay to disintegrate in water into granules more subtle in a certain time and the air temperature biasa.Bila clay put into water, the clay gets wet then expands, then clay crumbled into part- part kecil.Semakin less holding capacity of clay, the faster the destruction. Clay is soft and porous tend to disintegrate faster in water than hard clay. The slaking properties associated with the softening of the clay.
