Archaeometallurgy Laboratory

Archaeometallurgy Lab.

The Archaeometallurgy Laboratory at CAAM facilitates research and teaching on ancient and historical metal objects and their production. Research centers on material characterization, pyro-technologies, and various technological and craft processes related to the production and use of metals throughout history.

The laboratory is equipped for the analysis of metals and a host of materials from traditional metal production processes (e.g., ore, ceramics, slag). Equipment to prepare samples for standard metallographic analysis is available in the Wet Lab. Instrumentation for optical and electron microscopy and chemical analyses sits across the hall in the Archaeometallurgy Lab, a shared space for the characterization of organic and inorganic archaeological materials. The Archaeometallurgy lab also houses an extensive sample collection representing much of the archaeometallurgical research performed over the years at the Penn Museum and the University of Pennsylvania. The collection is used regularly in CAAM courses and by scholars for research and training.

Current Research Projects

The lab is also part of the CAAM Pyrotechnology Research Group (CPRG).


One of the finest resources in the Archaeometallurgy lab is the mounted sample collection inherited from the influential work of MASCA and ongoing archaeometallurgical research in CAAM. The sizable collection holds samples of metal objects, mostly copper and iron alloys, and production artifacts that represent metal production technologies throughout the history of metalworking on a global scale. The collection is used regularly as a teaching resource in CAAM courses and in continued analysis by researchers worldwide.

The Archaeometallurgy lab is in the process of building an interactive collection of materials representing the technologies and materiality of metal production. The collection is composed of representative, ethnographic, and experimental materials, such as ores, technical ceramics (crucibles, tuyeres, furnace linings), and slag. This assemblage complements the large body of metal samples held in the mounted collection. These materials are used in course work to provide an instructive and tangible way to interact with complex technologies of the past and allow students to become familiar with materials that are often rare in the archaeological record.
