· 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.
