Mount Making for a Special Object

I recently had the opportunity to create a cavity mount for a double cylinder jar that is from Pueblo Bonito in Chaco Canyon, New Mexico. This artifact is very special because only one double cylinder jar has ever been recovered from Chaco Canyon.

Chaco Canyon is a large archaeological site located in northwestern New Mexico. It is believed that people have inhabited the region for over 10,000 years, with large scale occupancy occurring between AD 700 and 1300. This period is known as the Pueblo period. Architecture at Chaco Canyon ranged from domestic dwellings to large, multi-story complexes. These multi-story buildings are known as Great Houses, the largest of which is Pueblo Bonito. In addition to these structures, Chaco Canyon also contains large subterranean rooms called Kivas. Kivas were typically used for ceremonial purposes, and the largest kivas could hold hundreds of people. Eventually Chaco Canyon was abandoned by its inhabitants for reasons that remain unknown. It is believed that drought was a significant factor in its abandonment.

In order to make a mount for this vessel, I needed to find a block of archival ethafoam large enough to hold the vessel. Once this was located, I carefully traced the shape of the jar into the foam. I then used a hot knife to essentially melt and cut the foam out, forming the cavity in which the vessel would rest. This part was awesome, and I got to work outside so that the smoke and fumes of melting foam didn’t set off the fire alarms. Once the cavity was made, I lined it with Tyvek paper, which is an archival material that will not damage artifacts while providing a smooth surface on which to rest. Once the Tyvek was in place, the vessel could rest inside its new home. To see a video of cavity mount making check out this link . It’s not a video of me making this mount, but the process I used was exactly the same. Now this one of a kind vessel is happily resting in a mount instead of just in a cardboard box.

The double cylinder vessel is housed in one of the drawers from our Adopt A Drawer program. If you are interested in adopting a drawer at the Peabody feel free to contact us!
