During the last years, the group of the Analytical Chemistry section of the University of Barcelona in collaboration with Dra. Lourdes de Sanjosé, specialist in medieval goldsmithing, has focused part of her research on the enamels of Llemotges, which was the most important center for the production of enameled objects during the Middle Ages.

The University of Valladolid has published the results of the research project  Retablos-tabernacles of the Lower Middle Ages in the Crown of Castile: study, documentation and diffusion , financed by the Ministry of Economy, Industry and Competitiveness with the support of the European Regional Development Fund.
