Forgery or authentic. xrf-analyses on selected objects of the Estrada collection, Portugal.

In this paper, we present the most relevant results of an archaeometric analysis of some objects of the Estrada Collection. It was discovered that a signi!cant number of them were false despite looking authentic from a stylistic point of view. We conclude with the recommendation that museums that accept objects from private collections whose provenance is unknown, should make archaeometric analysis, since these constitute a very reliable way to determine the authenticity of the objects.
