Guggenheim, S. (1997) Introduction to the properties of clay minerals. Published in "Teaching Mineralogy," ed. by J. Brady, D. Mogk, and D. Perkins, by the Mineralogical Society of America. Copies may be purchased through the Mineralogical Society or the Clay Minerals Society. A "discovery-type" laboratory that shows how different cation exchanges of montmorillonite clay can change the properties of clay, including dispersion/flocculation properties, the effect of salts on swelling and permeability through a sand column, filtering and adsorption, etc. Requires balances, beakers, glass tubes, and clay. The lab may take 2-3 hours but can be done in part or over several class periods. Suitable for juniors in high school or older. Introduction includes clay definition, crystal structure descriptions, and chemistry discussion that may be reduced or eliminated.
