Welcome to the International Association for Obsidian Studies (IAOS) home page. From here, you can find out about the IAOS and explore technical information related to obsidian characterization ("sourcing") studies and obsidian hydration dating methods.
IAOS BULLETIN 66 IS OUT: All issues of the IAOS Bulletin are available for downloading as searchable Adobe Acrobat documents and single back issues can be downloaded using the drop-down menu below. And don't forget that a cumulative and searchable PDF of all IAOS Bulletin issues is also available in the Member's Lounge.
INTERDISCIPLINARY JOURNAL SEEKS CONTRIBUTIONS ON OBSIDIAN: The University of Oregonís Center for Art Research is facilitating a symposium and related publication with the Chipstone Foundation as a way to work toward an issue of their new publication, Material Intelligence, focused on Obsidian. A symposium dedicated to this material will be facilitated in the fall of 2021 and the related publication will be released spring/summer 2022.
Material Intelligence is a nascent endeavor that seeks to promote discourse about materiality across disciplines by focusing each issue on the investigation of a specific material through a variety of lenses. Each issue is an aggregation of perspectives from people with a variety of lived experiences and connections to disciplines ranging from Art, Design, and Craft to Anthropology, Engineering, Philosophy, Chemistry, etc. After our fall symposium, approximately five speakers will write pieces for an issue dedicated to that material.
If you or someone you know may have a special relationship to or expertise with obsidian, please forward names or register your interest in participating by emailing Brian Gillis, CFAR Director, at email@example.com. Such folks can be artists, scholars, scientists, or laypeople of any ilk. Once CFAR has had some initial conversations with potential contributors, we will forward a list of interested contributors to the Chipstone Foundation and the Material Intelligence editorial board will contact people directly to better explain the project and what kind of support they can offer for the participation.
A SUCCESSFUL 2021 INTERNATIONAL OBSIDIAN CONFERENCE: Due to the threat of COVID-19 and the cancellation of University of California-Berkeley in-person gatherings, the date of the 2021 International Obsidian Conference (IOC) was changed from April 10-13 to April 30-May 2, 2021. Hosted by the International Association for Obsidian Studies (IAOS), the Archaeological Research Facility (ARF), and Far Western Anthropological Research Group (FW), this event was virtual and free for participants and attendees. An updated copy of the IOC Program can be found HERE.
Thanks to Nico Tripcevich, lightly-edited video recordings of most of the 2021 IOC talks are now available on YouTube:
The 2021 IAOS Annual Meeting was also held in conjunction with the conference. To have a look at the minutes of the meeting, click HERE.
THE IAOS PDF LIBRARY: We're assembling a collection of obsidian-related theses and dissertations, all in searchable Adobe Acrobat (PDF) format. If you have a thesis or dissertation that you'd like to contribute, we would very much like to hear from you. To add a reference to the library, simply send an email to firstname.lastname@example.org, write "IAOS LIBRARY" in the subject line of the email, and attach the PDF that you'd like to contribute.
IAOS BULLETIN INDEX: We've added a separate index to all articles published in the IAOS Bulletin. To have a look, click HERE.
IAOS SOURCE CATALOG REVIEWERS ARE NEEDED: While we continue to maintain the IAOS World Obsidian Source Catalog, our knowledge of obsidian sources outside of the United States and Canada is sometimes incomplete or inaccurate. We would like to invite any regional obsidian source specialists to have a look at the Source Catalog and get back to us (see the email address above) if you spot any problems. We'll be happy to acknowledge your participation and we'd like to thank Dr. Maria Victoria Fernandez for her help in sorting out sources in Patagonia (Argentina and Chile), South America.
TWENTY-FIVE YEARS ON THE CUTTING EDGE OF OBSIDIAN STUDIES: Edited by Carolyn Dillian, this volume of selected readings from the IAOS Bulletin is still available for online ordering at $10 per copy (plus postage). Click HERE for a sample and all the details on how to instantly order your copy. For a review (PDF) of the book, click HERE.
IAOS EXTRAS: Be sure to have a look at the IAOS Extras page for some obsidian-related tools and resources that fall into their own unique category. These include several obsidian hydration-related tools and documents put together by Sandy Rogers and, most recently, a spreadsheet listing of obsidian-related references assembled by Chris Lloyd (updated 06-12-2019). This reference spreadsheet now contains over 5,000 literature references. The collection of references has now been ported to Zotero, an online searchable research tool, by Nicholas Tripcevich.
