Project
Non-destructive research methods for archaeological glass
CARRIED OUT BY DELFT UNIVERSITY OF TECHNOLOGY AND VARIOUS PARTNERS
This research project looks for links between movable and immovable heritage. When glass is found at an archaeological site, the questions that are asked can also be asked for stained glass windows: where was the glass produced, what is its physical condition and is there risk of decay? The advantage of movable heritage is that it can be taken to research laboratories. Because this is not possible with stained glass windows that are still intact, representative samples are used instead, and the research conducted on these samples is then translated into methods that are applicable on site. This project focuses on developing non-invasive, reliable research methods that do not require destructive sampling.
Finds of Roman, medieval, 19th and 20th century glass objects, shards and ‘duds’ can provide a lot of information about the manufacturing process, origin and age of original church windows.
The project focuses on antique window glass, Roman glass objects and the glass collection from Palmyra at the Allard Pierson Museum. The research group wants to find out more about the chemical composition of the glass and whether this can be linked to its provenance, local peculiarities and historical trade networks. Through the ages, glass recipes and manufacturing processes have evolved, influencing the ageing and inherent properties of glass.
The research team is exploring the complementary use of different scientific research methods and best practices. The group is using technologies such as neutron and X-ray tomography, X-ray fluorescence spectroscopy (XRF), gamma spectroscopy and optical coherence tomography (OCT) to study historical glass and various types of glass degradation. Together, they are trying to answer questions related to the interpretation, provenance, condition, conservation and restoration of glass.
The consortium consists of a diverse group of people who approach historical glass research from different angles. It aims to establish partnerships with various national and international institutions, such as heritage managers, museums and research groups.
