XRF Characterization Of 18th Century Piedmontese Porcelains From The Palazzo Madama Museum (Torino, Italy)

Around 100 porcelain objects of the 18th century Rossetti, Vische and Vinovo manufactures (Piedmont, Italy) from the Palazzo Madama Museum collection were analysed by means of an X‐ray fluorescence portable detector. The present study represents the first chemical characterization of these early (1737–1825) European porcelains. Chemical composition data were submitted to multivariate clustering techniques that underscored a complete classification of the three manufactures and the presence of three subgroups for the Vinovo production. These resulting subgroups did not mirror the classification expected on the basis of the historiographic literature. The overall data pointed to technological continuity not only through all the Vinovo phases but even continuing from the earlier Vische manufacture.
