The natron-based glass industries


Glass sourcing using advanced analytical techniques

Glass made using soda from Egypt or “natron” dominated the production of the later first millennium BC through to the end of the first millennium AD and is particularly characteristic of the Roman period.  This project uses advanced analytical techniques to determine the sources of the glass (largely in the Near East), the technology of production, and the structure of the production complex.

The project has evolved through a number of sub-projects and has included: characterisation of large primary glass making centres in Israel; development of the “divided production model”; development of innovative trace element and oxygen and strontium isotope methods for the investigation of provenance; demonstration that most Roman and early medieval glass material in Britain was imported from the Near East; demonstration that individual batches of glass may be identified in both consumer assemblages and in workshops; etc.

Current sub-projects include:

  • (1) differentiation of glass made in Egypt and different parts of the Levant through trace element analysis
  • (2) origin and technology of HIMT glass through trace and isotopic analysis
  • (3) glass from wreck sites off the eastern Mediterranean coast
  • (4) glass production at Basinghall St, London
  • (5) Hellenistic glass composition and production
