This study investigates the materials and techniques used in three Mexican platters, or bateas, from the Victoria and Albert Museum collection. Our analytical approach included the use of non-invasive techniques, such as infrared reflectography, scanning X-ray fluorescence, and digital microscopy, which informed limited but targeted sampling. Traditional pigments were identified, including indigo, carbon black, red lead, lead white, and orpiment, and materials such as dolomite, gypsum, ochres, and clay were also found. A red organic dye was seen but could not be identified. The stratigraphy of the objects was also investigated. The condition of the objects was also evaluated, and the results will be used to inform future conservation decisions. The findings add to the published knowledge of the materials and techniques of early colonial Mexican objects and can be of use in future investigations, facilitating exchanges and collaborations focused on this type of objects, which are rare in UK collections.

This paper summarises the research carried out so far on barniz de Pasto objects from the Victoria and Albert Museum (V&A) and outlines future areas of development for our collection of Indigenous lacquer from Latin America. The V&A was the first UK public institution to identify objects decorated with barniz de Pasto within its collection. Two of these were acquired in 2015 and 2018; others had entered the collection between 1855 and 1902 but were recognised as barniz de Pasto only after 2018. The acquisition in 2015 of a cabinet marked the start of a research campaign to understand the materiality and context of all the museum’s barniz de Pasto objects. The analytical techniques used included X-radiography, polarised light microscopy and digital microscopy, Raman microscopy, X-ray fluorescence (point and scanning), chromatography (py-GC–MS and LC–DAD–MS), Fourier transform infrared spectroscopy, X-ray diffraction, and X-ray micro-computed tomography. Unexpected discoveries were made along the way, including the characterisation and documentation of mercury white (mercury(I) chloride, or calomel) used as a white pigment, a world first. Gel-based cleaning methods were used to remove a non-original, discoloured, natural varnish covering nearly the entire surface of one of the objects, and the recent overpaint on its lid, revealing original surfaces which had been repaired and drastically repainted in the second half of the twentieth century.

This paper seeks to reassess the iconography and the physical condition of a fourteenth-century carved and painted casket in order to review its geographic origins and to consider its function. The intriguing, but under-researched casket (now in the Victoria and Albert Museum) has been discussed mainly in terms of the Tristan iconography of its lid, apparently derived from a German version of the Tristan story. Yet the casket has been generally described as English or French. In order to review these conflicting assumptions, and to exclude the possibility of a nineteenth-century forgery, the casket was reassessed technically, and the well-preserved polychromy was found to be consistent with a fourteenth-century date. Using stylistic and iconographic analyses, a Netherlandish origin of the casket (around 1350–70) is tentatively proposed. Within the context of the controversial discussion ofMinnekästchen, the casket is finally interpreted both as a practical object and as the bearer of a coded language of love.
