Experimental and Archaeological Sciences Lab (EASL)

Support Archaeological Science at the Cotsen

  
Archaeologists and cultural heritage professionals here at the Cotsen Institute of Archeology spend part of the year doing fieldwork, in remote locations, uncovering the mysteries of how people lived in the past. But exciting discoveries can still be made in the laboratory. In fact the lab is where most of the work of archaeologists takes place, processing and analyzing the recovered material! The importance of laboratory work in archaeological research is why we are asking for your help to purchase scientific tools needed by our graduate students. Right now, we have an opportunity to help students build and analyze robust data sets from previous field work. But we need your support.  

Please donate to the Cotsen archaeological science labs to help graduate students conduct their research. You can support us by clicking the "Learn More" button and selecting the "Costen Equipment Fund" in the drop down menu.

EASL is a research lab for the study of past cultures and materials through experimentation, scientific analysis and STEAM (science, technology, engineering, arts, and mathematics) education. 

All students, affiliates of the Cotsen Institute, and volunteers are welcome to use the resources available in EASL. To receive more information about the lab, reserve equipment, schedule a research consultation, or enquire about volunteer opportunities, please contact us.

EASL Logo

The Experimental and Archaeological Sciences Laboratory (EASL) is a collaborative research space dedicated to the study of ancient materials and technology through replication experiments and scientific analysis. The lab assists students, faculty and Cotsen affiliates with their archaeological research projects, as well as offers resources for laboratory-based courses. The work conducted plays an integral role in fulfilling the Cotsen Institute of Archaeology's mission to create, disseminate and conserve archaeological knowledge and heritage.

Equipment

The lab was established in the second half of 2018 in what used to be the European Archaeology Laboratory (room A419) and officially opened in the fall of 2019.  EASL currently houses equipment for the examination and analysis of archaeological materials, as well as for the replication of archaeological artifacts and technological activities . This includes:

  • a traditional kick-wheel and a modern electric potter’s wheel for experimental pottery making
  • a small electric kiln for experimental production of pyrotechnological materials like ceramics and faience
  • a selection of microscopes, including stereo-microscopes, reflected, transmitted and cross-polarized light microscopes
  • sample preparation equipment for grinding and polishing of petrographic thin-sections and mounted samples, as well as hot plates and centrifuges
  • several portable X-ray fluorescence spectrometers for material analysis

 

You can find a list of the available equipment here.

Current Projects

Identification of Neolithic Pigments from Masis Blur

This project aims to identify raw pigments excavated from the Neolithic settlement of Masis Blur (7000–6400 cal. BP)  in modern Armenia using techniques such as polarized light microscopy and pXRF. Once identified, the work will shift to determine how these pigments, and the spaces that they were found in, were used, and where the materials came from to provide information on craft specialization and long distance trade activities at Masis Blur. This project is a collaboration with Dr. Kristine Martirosyan-Olshansky, Director of the Armenian Lab at the Cotsen Institute and co-director of the Masis Blur Archaeological Project. 

 

Making Ancient Egyptian Faience

A series of replication experiments have begun on the manufacture of ancient Egyptian faience, a glazed siliceous ceramic material. The experiments will look at different faience recipes, forming methods,glazing techniques, and firing conditions used to produce these objects. The goal of the project is to come up with a method to produce it here in the lab and create a hands-on workshop on the technology of ancient faience. 

 

PXRF Analysis of Copper Alloy Artifacts from Lofkend

This projects looks at the applicability of portable XRF spectrometry for the compositional analysis of copper alloy objects from the Late Bronze Age/Early Iron Age tumulus at Lofkend.  A methodology will be established for the quantitative analysis of very small samples taken from the artifacts. The results will be used to understand the types of alloys used to manufacture items of personal adornment (fibulae, earrings, spiral ornaments).  The results of this study will complement an earlier metallographic study conducted on this same group of samples. 

 

Analysis of Glass Production Debris from Petrie’s Excavations at Amarna

Different analytical techniques are being used to characterize the composition of the glass waste and identify the raw materials used in the production of vitreous materials at the site. The results will also help identify what stages of glass manufacture this archaeological evidence represents adding to the data collected so far on the Late Bronze Age glass industry in Egypt and the broader eastern Mediterranean region.  This project is funded in part by the American Research Center in Egypt's (ARCE) Antiquities Endowment Fund (AEF).
