High-Tech for Archaeology – Local support enables exciting insights into hidden structures

During field research at the large Late Iron Age and Early Roman Iron Age urnfield cemetery of Nienbüttel (Uelzen district), several hundred artefacts were recovered. These are currently being scientifically analysed at the NIhK as part of the research project »Rituals in a new light – Modern field research, documentation and visualisation strategies using the example of the burial ground of Nienbüttel«. While bronze artefacts typically allow for an immediate assessment of decorations, construction details, or surface structures (e.g., traces of burning) after cleaning in the restoration workshop, iron artefacts often appear as amorphous lumps of corrosion. Therefore, non-invasive examination is essential before further processing (desalination, abrasive cleaning, and conservation). Fortunately, the NIhK benefits from the support of local service providers. Initial attempts by the Friedeburg-based company tbd to examine iron artefacts using X-ray technology have already revealed numerous fascinating details.

Active support was also available locally for the radiographic examination of larger and more compact units, such as urns recovered from blocks. At the radiological office GeRN GbR in Wilhelmshaven, computed tomography was used to analyse the two bronze vessels from the stone packing, one of which is certainly an urn. Not only was the paper-thin wall of the vessel clearly identifiable, but its contents—including the cremation remains and any accompanying grave goods—were also visible. This examination provides a valuable basis for further conservation and restoration work. In March, two students from the Stuttgart Academy of Fine Arts will return to the NIhK to continue the fascinating work they began last year.
