The statuette dates to Egypt's 12th Dynasty. When the statuette was damaged, it was considered the appropriate time to obtain valuable information

While X-rays fail to penetrate the brass matrix of the samples, neutrons can easily reveal, on a non-invasive manner, the content and structure of these precious samples.

This nationally significant collection of gold artefacts has been researched since the 1930s, but active conservation began only in 1999 to ensure its long-term preservation. The focus of this article is mainly on the stabilization of the entire gold collection, which involved efforts to arrest fragmentation, re-unite dissociated fragments and bring about considerable
improvements to the collection
