For the first time, twenty spun polychrome glass figurines (considered as tangible cultural heritage objects) stylistically assigned to workshops of the city of Nevers from the 17th to 19th centuries have been analyzed at the Musée de la Faïence et des Beaux-Arts of Nevers using non-invasive XRF and Raman spectroscopy. The results are compared with those previously obtained for figurines assigned to the Perrot’s Orléans workshop. A wide variety of glass compositions is observed, ranging from lead-free to lead-rich compositions, which are attributed to the preparation technique that involves mixing glass stems of different origins during the creation of the figurine. White opacification is achieved with Ca2Sb2O7. The cobalt source is consistently arsenic-rich, but its composition becomes more complex during the 18th century, indicating the use of different cobalt sources. A variety of lead-tin and Naples yellow pigments are identified. Metal nanoparticles are used for pink, ruby, and carnation colors. The detection of associated arsenic and/or tin supports the identification of the use of gold nanoparticles. Cassiterite and arsenates of lead/calcium/potassium are also detected in a few figurines, probably from a different workshop. This latter opacifier, being more frequent in previously studied artifacts assigned to Orléans, suggests that the assignment to Nevers could be questioned. Aventurine glass is present in two objects.
