Back in business

Saturday April 8th is the official reopening of the Artifact Lab, complete with a modified name and some new objects on exhibit and in the lab.

The Artifact Lab: Conservation in Action looks a lot like it did before we closed in December, but as you can see from the shot above, our focus has shifted from Egyptian mummies and funerary objects to a wider range of artifacts, with a special focus on objects being prepared for installation in our Middle East Galleries next year.

This glazed clay slipper coffin from Nippur, excavated by our museum in the late 19th century, is front and center in the Artifact Lab:

It has a fascinating history, including its restoration here at the museum in the 1890s, which is noted on its catalog card as being carried out by the restorer William H. Witte. The restoration work allowed this coffin and several others to be displayed for the opening of the new museum building in 1899, where they remained on display for 40 years. We are particularly tickled that this coffin was displayed in this very same gallery where the Artifact Lab is now housed, the Baugh Pavilion.

118 years later, the slipper coffin has once again been installed in this space. It’s exhibition this time would not be possible without the extensive treatment carried out by conservator Julie Lawson in 2005. You can read more about its history and her work in her article in Expedition Magazine. For those interested in a more in-depth discussion of the conservation treatment, Julie also wrote an article that was published in the American Institute for Conservation’s Object Specialty Group Postprints, Volume 13, 2006.

There are many more stories to share about the objects and work being done and we’ll continue to write about them on our blog. In the meantime, come visit us now that we are open again! Our open window times also have changed slightly – they are now as follows:

Tuesday – Friday 11:00 – 11:30 and 1:30-2:00

Saturday – Sunday 12:00-12:30 and 3:00 – 3:30

Fragmentary painted coffin from Abydos

If you are a member of the museum, you may have already seen some information about these painted coffin board fragments in the most recent issue of Expedition magazine:

E12505_2These fragments, which date to the Middle Kingdom (ca. 2000-1700 BCE), were excavated from the North Cemetery of Abydos in 1901 by John Garstang. The museum supported Garstang’s work through the Egypt Exploration Fund.

Despite the severe insect damage, the preservation of the painted details on these fragments is remarkable.

This fragment features 3 usekh collars, which were often reserved for nobility. Beside each collar is a mankhet, or counterpoise. The hieroglyphs above are the names of each of the collars, which are slightly different.

These coffin board fragments have never been exhibited, and our renewed interest in them is due to the fact that we are currently excavating tombs from the same time period in South Abydos, including the funerary complex of Senwosret III. You can read a lot more about this project in the recent Expedition issue and on the museum blog by following this link.

In order to exhibit the coffin fragments, they need some extensive conservation treatment. Their surfaces are dirty, the paint is cracked, cupped and lifting from the wood support, and is very fragile, and some of the boards are structurally unstable due to the extensive insect damage.

We are currently working on these boards in the lab, and we have made some good progress. We are cleaning the painted surfaces with a kneaded rubber eraser. The eraser can be shaped to a fine point, and working under the binocular microscope, it is possible to remove the dirt from most of the painted surface without disturbing the fragile paint.

Some areas of paint need to be stabilized before they can be cleaned. After testing a variety of adhesive solutions, I settled on my old friend methyl cellulose, a 2% solution of methyl cellulose in water to be exact, to consolidate fragile areas.

I am now working on testing some fill materials, both to stabilize the edges of lifting paint and also to stabilize the fragile wood. I will post an update as soon as I make some decisions and proceed with this part of the treatment!
