The natural bentonite was purified in the laboratory to remove calcite, carbonates, and organic matters by the following protocol: the sample was first repeatedly washed with Milli-Q water and dried after each time. The dried bentonite clay (25 g) was soaked in 400 mL solution containing Na-Ac (0.1 N) and Ac-Ac adjusted to pH ≈ 5.0.

Wet green pellets started showing plastic behaviour as they became over-saturated. At over-saturation, balling was a self-regulating process striving to keep the liquid saturation constant. At over-saturation, an explosive increase in plasticity with increasing moisture content was seen due to the contemporary increase in porosity.

The reason for this warning is that when bentonite gets wet, it swells and gels, sticking together and forming clumps that make it tricky to incorporate into the rest of the glaze. If you were to weigh out some bentonite, dump it into a wet glaze and start mixing, the bentonite would clump together, making the glaze lumpy. ... The process is ...
