Abstract

The different phases in the life of archaeological objects can be described by artefact biography. This dissertation defines an updated version: artefact biography 2.0, and the life phases of Early Iron Age bronze studs from Oss-Zevenbergen, the Netherlands, are elaborated. Throughout the thesis, the research revolves around information value.

The bronzes have been studied from an interdisciplinary point of view, which has allowed the extraction of information that is also applicable to other corroded bronzes in general. It is argued that:
- corrosion products and inclusions may reflect original microstructure‚Ä®
- corrosion inhibitor BTAH binds to Sn and SnO2
- technical investigations before conservation increase the information value of an artefact.
