Important Criterion
Slip(Slurry) requires high solid content with controlled amount of water, with suitable of viscosity
To enable flowability, transportation, casting
-
Viscosity increase, fluidity decrease
Produced cast with good properties such as dense,solid with good green strength and not easily cracks
-
Addition of electrolyte ( known as deflocculant or dispersant) will reduce the viscosity to a minimum point before increasing the viscosity again
-
Common deflocculant: Na Silicate, Na Hexametaphosphate (Calgon), Na carbonate,Dispex, CMC
Viscometer
Torsional viscometer 
Brookfield viscometer
