Making some noise

We have been notably quiet on this blog lately, but that doesn’t mean that we haven’t been making a lot of noise elsewhere!

Project Conservator Anna O'Neill Alexander uses a PaleoTool to remove old restoration plaster that surrounds an ancient Egyptian limestone fragment. 
The limestone fragment is part of a column from the palace complex of Merenptah, 
which dates to 1224-1204 BCE.

We also have some BIG imminent deadlines, which have kept us very busy, and some of our monumental projects are so BIG that they can’t even be worked on within the Museum building. More on that soon.

All of that aside, we continue to work on projects in the Artifact Lab, that are not as big, necessarily, but are just as important. Most of the artifacts we are working on are to prepare for the future installation of our new Ancient Egypt and Nubia Galleries.

Project Conservator Teresa Jimenez-Millas is currently working on the coffin 
and mummy of Petiese in the Artifact Lab. Here she is using an adhesive 
solution to stabilize the painted surface of Petiese's coffin lid.

Petiese was an Egyptian priest who lived during the Late Period (664 – 332 BCE).

To hear more about all these projects in REAL TIME, check out our 1-hour #AskAConservator Q&A session next Monday, November 4th, on the Penn Museum’s twitter account, or visit us when the Museum is open, where EVERY day is Ask a Conservator Day!

As us anything! (on our Reddit AMA)

We open our windows in the lab twice daily, inviting our visitors to ask us anything, so why not open our windows just a bit wider, inviting anyone on the Internet to fire questions at us? We are doing just that, tomorrow, from 11:00-12:30 EST on reddit.com. I must confess that other than perusing Reddit a few times last fall while I, along with much of the rest of the world, listened to the first season of Serial, I have no experience using Reddit. According to it’s Wikipedia page, Reddit is an “entertainment, social networking, and news website” and content entries are organized by areas of interest called “subreddits.” One of the most popular subreddits is IAmA (“I am A”) where a user may post “AMAs” (Ask Me Anything).

So tomorrow, Wednesday March 11, from 11:00-12:30, Lynn Grant and I will be online for our very own AMA with the title “We are museum conservators working with ancient Egyptian artifacts in full public view, at the Penn Museum in Philadelphia. Ask us anything!

Tom Stanley, our intrepid Public Relations/Social Media Coordinator, set the AMA up, and posted instructions on how to find us on Reddit tomorrow if you’d like to follow along or ask us a question. You can find the blogpost with instructions by following this link.

Looking forward to hearing from you tomorrow!

Natron

Have you checked out our FAQs page? We hear lots of interesting questions in the Artifact Lab every day, and we’re posting some of the more frequently asked ones on there, and providing answers when possible.

We recently added more information about natron to our FAQs-What is natron and what was it used for? Natron is a natural mineral consisting of a mixture of sodium carbonate decahydrate with sodium bicarbonate, sodium chloride, and sodium sulfate-essentially, a salt. Natron was an important part of the mummification process. It was used by embalmers to pack the body, which would help preserve the body by drying it out.

We are interested in observing the presence of natron on objects in the Artifact Lab. One of our mummies, for instance, has a very fine, white, crystalline substance in areas on its wrappings, particularly on the inside of the wrappings. Here is what it looks like:

An example of the white crystalline substance observed on the surface of the textile wrappings on one of our mummies.

And this is what it looks like under the binocular microscope:

That same crystalline substance magnified 7.5X

We also see this on some of the human remains in the lab. Is this natron? We’re hoping to investigate this further.

Happy Anniversary, Penn Museum!

Conservator Julia Lawson speaks to visitors through one of the Artifact Lab’s open windows

Yesterday was the Penn Museum’s 125th Anniversary! To celebrate the event, the museum held a free Open House, and the galleries were open from 10am to 10pm. In the Artifact Lab, we kept our 2 windows open all day, and conservators Julia Lawson and Nina Owczarek were busy all day speaking with visitors and answering questions. If you made it in yesterday, thanks for coming out to support the museum! If you didn’t, remember that we have open window periods every day that the museum is open, which are:

Tuesday-Friday 11:15am and 2:00pm and Saturday-Sunday 1:00pm and 3:30pm

Looking forward to seeing you in the Artifact Lab!

Ask the conservator!

Since the Artifact Lab opened on September 30, we (meaning my fellow Penn Museum conservators and myself) have spoken to hundreds of people who have visited the exhibit during our open hours (Tues-Fri @ 11:15am and 2:00pm, Sat-Sun @ 1:00pm and 3:30pm). Being the full-time conservator in the Artifact Lab, I get to talk to lots of our visitors, and I have to say that it has been one of the most fun parts of my job.

Chatting with visitors during a Q&A time in the Artifact Lab

I particularly love it when people ask me questions. Many of these questions are about Egypt-and because I am not an Egyptologist, I have spent a bit of time looking things up, asking our curators, and often saying “I don’t know, but I’ll see what I can find out.” We try to post answers to some of the frequently asked questions here on our blog, and we encourage you to ask questions via this blog well, by leaving them at the end of any of our posts, or in the comments box at the end of the FAQs page.

But many questions are about conservation, and this is an area that I can talk a LOT more about. One conservation-related question that I have heard a lot lately is “what are you going to use to repair that object, and will you use the same materials as the original?”. This is a great question, and gives me the opportunity to talk a bit about conservation decision-making and ethics.

There is a lot to consider when making decisions about how to repair objects and what materials to use. No two objects are exactly alike, so what works for one object may not work for another that is very similar.

One of the first things to consider is the nature of the object-what is it made out of and what is its condition (and why does it need conservation treatment)? We are always looking to choose treatment materials that are compatible with the original materials of the object and that will provide the strength, cohesion, etc. that the object needs.

That being said, we also use materials and methods for treatment that make our work easily distinguishable from the original object. For example, many conservation treatments involve filling losses in objects with new materials and coloring the fills to blend with the surrounding original materials. When carrying out this work, many conservators use an approach known as the rule of “6 Feet, 6 Inches”-meaning that when an object is viewed at 6 feet the repair is not visible but at 6 inches it is easy to distinguish from the original. We also document all of our treatments thoroughly in written reports and photographs, so that in the future it will be clear what has been done.

Another factor when choosing treatment materials is their long-term aging properties-we don’t want to use anything that discolors or becomes brittle over time (such as Duco cement) or will be very difficult, if not impossible, to remove later (like Elmer’s glue!!).

There is a LOT more to say on this topic, and as we put up new posts about ongoing projects we we will try to include information about the decision-making process. In the meantime-Ask the Conservator! Let us know if you have a question-either come visit us during our open window times or leave us a question here!
