ABSTRACT:
A ball clay/water slurry which may be used to prepare ceramic sanitaryware articles is disclosed. This slurry contains from 58 to 68 percent of ball clay with a specificed particle size distribution, 42 to 32 percent of water, 0.001 to 1.0 of organic polyelectrolyte, and from 50 to 650 parts per million of soluble sulfate ion.
The slurry possesses rheological and casting rate properties which make it especially suitable for use in casting slips. It has a settling index of at least 0.9, a flow index of from 20 to 30 seconds, a casting rate of from 30 to 60 grams after 1 hour, and a transmission of at least 60 percent.
