We often talk about how we try to take advantage of new technologies whenever possible as part of the conservation examination and treatment of objects. It’s those new technologies that help us continue to learn and do more with objects that we have had for 100+ years. For example, even though x-ray radiography has been around since the late 19th century (see this image of the first radiograph ever captured in 1895) there have been major advances since then, including the development of computed tomography (CT-scanning) and digital radiography, so we frequently re-image objects that were x-rayed in the past to capture even more details (see this blogpost to see the recent radiographs we captured of our mummy Nespekashuti).
There are also many other new technologies that we use on a regular basis (at least in some instances), including our portable x-ray fluorescence analyzer (pXRF), our Mini-Crimescope, our Lynton laser cleaner, just to name a few.
But there are just as many, if not more, instances when the low-tech method or solution makes the most sense and gives the best, or just as satisfactory, results. I can provide many examples of this, but the latest low-tech approach that I’m taking in the Artifact Lab is figuring out how to examine and work on Nespekashuti and his coffin base.
I decided to tackle the treatment of Nespekashuti’s coffin before dealing with his remains. After working on all of the areas I could reach while it was sitting on a table, I realized that I needed access to the underside of the coffin. When I’ve worked on the back of other coffins, I first work on the exposed side and then flip the coffin over and work on the back (see a previous blogpost (including video footage!) Flippin’ coffins). The only problem with Nespekashuti and his coffin is that he is still inside, and I’m not ready to take him out yet (or ever…more on what I’m thinking about how to best preserve his remains in a future post). So, the best way to get at the underside was to put the coffin up on sawhorses, padded with Volara polyethylene foam.
This immediately allowed me to see some of the painted decoration on the underside, which I had never seen before:
I’ll work on the areas that are exposed and then I can move the sawhorses around to document and work on the areas that are obscured at the moment.
I’ve started to stabilize the flaking gesso, lifting linen, and paint in the areas I can access, and I’m securing these areas while they dry with plastic wrap, silicone-release Mylar, pieces of Volara foam, archival board, and weights.
So there is nothing high-tech about what I’m doing with Nespekashuti in the lab at the moment, BUT the treatment will eventually allow us to do more high-tech things with him, like CT-scanning, multispectral imaging…and anything else that we can gain access to that may help us learn more about him.
