Celebrating 50 Years of Professional Conservation at the Penn Museum

By: Nina Owczarek

The Conservation Department is celebrating its 50th anniversary this fall. The lab was first established in 1966 and is one of the first archaeology / anthropology conservation labs in the US staffed by professional conservators. In the early years, the focus was on conservation treatments. But under the leadership of Virginia Greene, who began working […]


A Conservation “Vacation”

By: Molly Gleeson

For three weeks in April, we had an intern working with us in the Conservation Department, specifically, with me in the Artifact Lab. I hesitate to call her an intern because this “intern” is someone who has at least ten more years of experience than I do as a conservator. In fact, she was one of […]


Of Daggers and Scabbards: Evidence from Organic Pseudomorphs and X-Radiography

By: Tessa de Alarcon

As part of the Ur Digitization Project, I have been spending time looking at the metal tools from the site.  As Kyra Kaercher has already noted in her blog post, many of the copper alloys from Ur have organic pseudomorphs.  These are sort of like fossils, in that they are organics which have been preserved […]


Ancient Repairs at Ur and the Power of Bitumen

By: Tessa de Alarcon

One thing that we all love to find on objects in the Museum collections are ancient repairs.  These are repairs made to an object during its period of use. So, imagine that mug you use every day for your morning coffee.  One day that mug breaks and you fix it with Super glue and go […]


Confronting Death at the Penn Museum

By: Molly Gleeson

After three years of working on ancient Egyptian mummies In the Artifact Lab, I’ve gotten used to being around death every day. And, in reality, all of us here at the Museum are surrounded by death – many artifacts in our collection were excavated from tombs and relate to funerary practices and provide intimate connections […]


Ask Us Anything!

By: Tom Stanley

Open since September of 2012, the Museum’s ongoing In the Artifact Lab: Conserving Egyptian Mummies exhibition continues to be a big point of interest and engagement among our visitors. In case you’re not familiar with In the Artifact Lab, the concept is pretty simple: it’s a combination of an exhibition and a working conservation lab. […]

Blue lines: multispectral imaging for pigment identification

By: Nina Owczarek

Visible-induced infrared (IR) luminescence is the invisible light that some materials produce when they are excited with visible light. We can capture that invisible light with a modified camera and use it to identify those materials and find out where they are. For those of you who follow the Artifact Lab Blog, this technique will […]


New Beginnings

By: Lynn Grant

In September 2014, the Penn Museum’s Conservation Department was able to move into our long-awaited new spaces. Funded by generous donors, including lead donors A. Bruce and Margaret Mainwaring, Charles K. Williams II, and Frederick J. Manning, the spaces were designed by Samuel Anderson Architects. In the newly renovated West Wing Conservation and Teaching Labs, […]


Standing on Stilts: The Glazed Ceramics from Ur

By: Tessa de Alarcon

In my last blog post I wrote about the process for firing some of the unglazed ceramics from Ur and I thought I’d follow that up with some information about the glazed ceramics from Ur. The firing of glazed wares is different from unglazed ceramics in a few key ways.  First they have to be […]
