ORDER SOURCE AND SPECIAL CLAYS

Please order source and special clays on-line: Order Online
DISCOVER, MASTERCARD, VISA, AMERICAN EXPRESS

You will complete a "Preliminary Pro Forma" and submit it on-line. The source clays repository will approve the pro forma and return it to you at your email address. You will be able to pay on-line through CMS online service or you may return the Pro Forma with the payment to the CMS Business office via mail or fax with your check or credit card information. Once your payment is approved the Source Clays Repository at Purdue University will ship your order.

We do not accept purchase orders.

In 2001, a series of papers on baseline studies of the Source Clays was published in the Society journal, Clays and Clay Minerals. The papers from that issue are available here, free of charge.

The prices for Source and Special Clays include Ground UPS within the continental United States. Other options including Air postage and International Shipping charges are additional. Please contact G.S. Premachandra at sourceclays@purdue.edu (Phone: 765 494 4258 or FAX: 765 496 2926) for more information about these charges.
The clays offered by the Source Clays Project change frequently because of new acquisitions and depletion of old supplies. The Source Clays Project is always grateful for new acquisitions, particularly of clays that have become depleted. If you are able to provide access to a new source of source or special clays, please contact the curator
