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 […]


When what you see is not what you get

By: Nina Owczarek

The museum is getting ready to install an exhibition on this year’s Penn Humanities Forum theme: Color. This alabaster head from South Arabia (30-47-17A) was selected for the exhibition to help illustrate how representations of human heads were achieved in stone in a variety of cultures and throughout time. When it first came to the […]


How We Do What We Do

By: Morgan Burgess

“Can you please explain what you’re doing?” is a question we hear daily. From a visitor’s perspective it doesn’t look like we’re doing much. Basically, we observe and document. A thorough condition report is the first step in any conservation treatment; we need to know what we’re dealing with. These murals are so large that […]


What ARE the Buddhist Murals Made Of?

By: Morgan Burgess

The questions most frequently asked of us while working on the Buddhist murals in the Chinese rotunda involve what the murals are made of. Often people presume they are frescoes. True fresco is done on wet plaster. The pigments used in a fresco are mixed with water and applied to a wet plaster surface. A […]


Conserving the Buddhist Murals: An Introduction

By: Lynn Grant

Just because artifacts have been in our collections or even on display for a long time doesn’t mean we know all about them. A case in point is the large Buddhist Murals in our Chinese Rotunda, probably the largest artifacts in our collection, at least in area. Although they’ve been on exhibition there since the […]

Mysteries of Kourion Revisited: a Mystery Solved!

By: Tessa de Alarcon

Awhile back I wrote a post, Mysteries of Kourion, about an unusual object from Kaloriziki Kourion (an archaeological site on Cyprus), which rattles when moved.  Last week I got to revisit the question of what exactly is making that noise, as this object along with a number of objects from the Egyptian section were taken […]


The Salty Pots of Ur and the Desalination Station

By: Tessa de Alarcon

In July, I joined the Ur Digitization Project.  As a part of this project, I have been working on a condition assessment of the ceramics from Ur.  In doing the condition assessment I am looking at, measuring, and evaluating the stability of every ceramic vessel in the Museum’s collection from Ur.  So far I have […]


Animal Imagery from Kourion Cyprus

By: Tessa de Alarcon

I finished up my part in the Digital Kourion project over the summer and to end it I wanted to highlight some of my favorite objects that I photographed from this unique collection.  These photos are now online as part of the Penn Museum’s Online Collection Database (Kourion). One of the things I found particularly […]


Treating Archival Treasures

By: Heather Brown

If you’re reading this blog, you probably know that the Penn Museum’s collection holds nearly one million archaeological and anthropological objects. What some may not know is that the Museum also houses an archive that holds 2,500 linear feet of records—documents, films, and images—about the collection, the history of archaeology and anthropology, the museum’s expeditions, […]
