| dc.description.abstractEn | During the second half of the 19th century, fabrication of ceramic pieces decorated with polychrome relief glazes occupied a prominent place in French factories of white earthenware. It is through the example of the production of the Vieillard and Co. Manufactory (Bordeaux, France, 19th century) that we will approach the technical study of this decoration process. A preliminary step towards the non-invasive study of objects in the museum's collections was taken through the study of archaeological sherds of this manufactory. Multianalytical methods were carried out in order to characterize both the clay support and the colored glazes. One of the aim of this paper is to implement a non-invasive approach of colored glazes study based on the development of optical techniques (reflectance spectroscopy and hyperspectral imaging). This methodology is intended to characterize colored glaze and more specifically to identify the types of pigments used not known in the text.A corpus of some pieces of polychrome glazed earthenware and decorated porcelain from Musée d’Aquitaine and Musée des Arts Décoratifs et du Design (Bordeaux, France) has been considered here. The selected pieces, representative of Vieillard and Co. decorative production, have a wide variety of colors. Twenty pieces, among them four color charts, were non-destructively analyzed in situ using a non-destructive hyperspectral imagery system. The data obtained made it possible to better understand the nature of the decoration chromogens and thus, to establish the color palette of the artists who produced this type of decorative objects. The goal is therefore to improve the database already established on hyperspectral imaging based on studies carried out on archaeological sherds and enriched by data acquired on color palettes.[1] Beauvoit E., Cantin N., Sireix C., Marache V., Chapoulie R., Ben Amara A., 2019.
