The Clay Minerals Society maintains a Source Clay Repository containing two series of materials, the Source Clays and the Special Clays. The list of available clays is posted at the Clay Minerals Society web site.
Minerals Research, probably the best source of natural zeolites, including a variety of clay and zeolite hand and reference samples and tetrahedral models of zeolites, unfortunately is no longer in business. Fred Mumpton will be missed by all.
