“…Non-stoichiometric spinels have also been identified by Pinto et al [202][203][204] with complex compositions in Ming blue-and-white porcelains by the combination of µXRD and Raman microspectroscopy: (Co x ,Fe y ,Mn z ,Ni u ,Mg v ,Cr w )Al n O 4 with 0.2 < x < 0.55, 0.3 < y < 0.9, 0.15 < z < 0.35 and 1.8 < n < 2.5; where the u, v and w content values are close to or less than 0.1.…”

“…The admiral was a significant figure during the 15th-Century with his several missions to Asian and African countries, marking the comprehensive Chinese overseas trade network with the west. Transmission electron microscopy and µ-X-ray Diffraction were also performed together with Raman microspectroscopy and SEM-EDS by Pinto et al [202][203][204] in order to measure precisely the composition of blue coloured grains in Chinese porcelain (see further).…”

“…Pinto et al [202][203][204] analysed Yuan and Ming blue-and-white porcelains in detail by a combination of µXRD, SEM-EDS, TEM and Raman spectroscopy. As demonstrated by the absence of additional Raman peaks in the signature of glassy silicate, Yuan porcelains were found to be coloured by dissolved Co 2+ ions in the glaze network.…”

“…The wavenumber shifts related to atomic substitution remain small and signatures of most of the spinels consist of a strong peak at ca. 680-700 cm −1 with smaller peaks at~200-300, 450 and 550 cm −1 (Figure 11) [202][203][204]220,[227][228][229][259][260][261][262].…”

Minerals able to colour in blue (and green in combination with yellow pigments) are limited in number and geologically. After presenting a short history of the use of cobalt as a colouring agent of glass, glaze and enamel in the Western/Mediterranean, Islamic and Asian worlds since Antiquity, we will present the different forms (dissolved ions, natural and synthetic crystalline phases/pigments) of cobalt and associated elements regarding primary (transition metals) and secondary geological deposits (transition metals and/or arsenic, bismuth, silver). Attempts to identify the origin of cobalt have been made by many authors considering the associated elements but without considering the important modifications due to different processing of the raw materials (extraction/purification/formulation). We review the information available in the ancient reports and present literature on the use of cobalt, its extraction and production from the ores, the different geological sources and their relationship with associated elements (transition metals, bismuth, arsenic, and silver) and with technological/aesthetic requirements. (Partial) substitution of cobalt with lapis lazuli is also addressed. The relative application of non-invasive mobile Raman and pXRF analytical instruments, to detect mineral phases and elements associated with/replacing cobalt is addressed, with emphasis on Mamluk, Ottoman, Chinese, Vietnamese and Japanese productions. The efficiency of Ni-Zn-As diagram proposed by Gratuze et al. as a classification tool is confirmed but additionally, CoO-Fe2O3−MnO and CoO-NiO-Cr2O3 diagrams are also found as very efficient tools in this research. The relationship between the compositional data obtained from the artefacts and historical questions on the origin and date of their production are discussed in order to obtain a global historical view. The need of a better knowledge of (ancient) deposits of cobalt ores and the evolution of cobalt ore processing with time and place is obvious.

“…Archaeometry studies focusing on Chinese ceramics have been ongoing since the mid-20th century until our days. 4,6–12 Analytical techniques, such as X-ray fluorescence (XRF), particle-induced X-ray emission (PIXE), and inductively coupled plasma mass spectrometry (ICP-MS), have been used for compositional analysis of glazes, colourants and ceramic bodies, helping to create a consistent collection of data regarding this ceramic production. 13–15 The investigation of the cobalt sources has been an essential topic for establishing a direct relationship between the cobalt-bearing minerals used as raw materials for the blue pigment production.…”
