What is Thin Sectioning?

Thin-sectioning (also known as, thin-section analysis) is an important technique used in Archaeology for the examination of the composition of various materials. Typically, such materials include ceramics or stone.

Thin-sectioning is the removal of a very thin piece (roughly 0.03 mm) of material from the object in order to be observed under a microscope. The sample needs to be so thin that the details of the material (small internal structures, and crystals) are readily displayed in the microscope in order to undergo proper analysis. This method is crucial in determining the raw material used for the specific object, or in the case of faunal remains, determining how the animal was killed. While we are able to obtain crucial information from thin-sectioning, it has some limitations. For instance, thin-sectioning is an abrasive method which doesn’t align with the archaeological view of limiting destructive analysis techniques on artifacts.

 

Thin sectioning is only done on samples with no accompanying context. Here samples are first coated with epoxy to create pucks that are later cut to a thickness of 30 microns.

International Archaeology Day: What You Need to Know

On October 21st, hundreds of organizations across the world will be holding workshops, fairs, and lectures for International Archaeology Day.

“International Archaeology Day is a celebration of archaeology and the thrill of discovery. Every October the AIA and archaeological organisations across the United States, Canada, and abroad present archaeological programs and activities for people of all ages and interests. Whether it is a family-friendly archaeology fair, a guided tour of a local archaeological site, a simulated dig, a lecture or a classroom visit from an archaeologist, the interactive, hands-on International Archaeology Day programs provide the chance to indulge your inner Indiana Jones.”

Interview with Bioarchaeologist Dr. Andrew Nelson

Dr. Andrew Nelson, Western University

MOA had the opportunity to sit down with Dr. Andrew Nelson, an Associate Professor in Anthropology at Western University, to discuss some of his more recent work, including his contribution to the Art Gallery of Ontario’s Small Wonders exhibition, which includes a Virtual Reality Medieval Prayer Bead, now available at MOA.

Andrew’s research interest are focused in two major subfields of anthropology: biological anthropology and archaeology. When he is not scanning artifacts in Sustainable Archaeology or working on the many research projects at Western University, Andrew can be found navigating the complexities of archaeological sites both local and abroad.

Negotiating Authenticity: Engaging with 3D Models and 3D Prints of Archaeological Things

If you’ve ever been really excited to go to a museum exhibition only to discover later that part or all of the display was made up of replicas, you’ll know that, for some reason, people tend to feel differently about the “real thing” than they do about the “copy” or the “fake.”  People have fascinating relationships with things and their copies. Sometimes we don’t know or understand where our own impressions of authenticity come from, or why we feel better about certain modes of representation and replication than we do about others. While some might really enjoy looking at a 3D model of an artifact on a screen – zooming in to take a closer look, flipping it around to see its different sides – others might prefer seeing the original artifact in a glass case in a museum. Still others might prefer to hold a 3D printed replica, able to run their fingers over the surface of the object and heft it in their hand. A lot of this is pretty subjective. Read more
