Optimization of X-ray Techniques for the Characterization of Tinplate Toys 

This master’s thesis aims to optimize methodologies based on X-ray analytical techniques—specifically X-ray fluorescence spectrometry and scanning electron microscopy coupled with energy-dispersive spectroscopy, among other relevant approaches—to characterize the stratigraphy and determine the tinplate production techniques used in the manufacture of historic toys. A central goal is to enable this characterization through fully non-destructive procedures, ensuring the physical integrity of the objects is preserved.

In addition to essential experimental measurements, the project will develop analysis methodologies grounded in Monte Carlo simulations, with the objective of constructing highly realistic models of the materials and layers present in tinplate toys.

The results are expected to deepen understanding of the technological evolution associated with these objects. In particular, by measuring coating thicknesses, the study aims to distinguish between different metal deposition techniques—such as electroplating and electrodeposition—and thereby support more accurate chronological attributions of tinplate toys.
