Bentonite properties include the ability to expand to ten times its volume when completely hydrated. It creates a very viscous, slippery, almost gel-like slurry that acts as a lubricant. The viscosity (runniness) of the slurry can be manipulated by adding water to make it thin or adding more bentonite to make it thicker. These properties
