Summary: In 2008, over 300 stolen ancient scrolls, including precious illuminated ones, were recovered in Chicago (USA). These scrolls, dating from the 14th to the 19th century, contained private and public documents, including papal and royal ones. They were returned to Italy and 42 of them, known as the Chicago Parchments, are currently preserved at the State Archives of Bari (Italy). Through non-invasive analyses using portable X-ray fluorescence (XRF), mu Raman, and fibre optic reflectance spectroscopy (FORS), the pigments, binders, and animal skin origin of the parchment were identified.

Summary: The yellow coloring of large Buddhist paintings during the late Joseon dynasty was analyzed using Raman spectroscopy and non-invasive component analysis. p-XRF analysis confirmed the use of gold, orpiment, and organic pigments, but not the yellow chromophoric elements of the organic pigments. Microscopic analysis revealed no particles or crystals, and the identification of light elements or organic compounds via p-XRF was challenging. Raman spectroscopy detected gamboge in the presumed organic pigments, either alone or mixed with white inorganic pigments.

Summary: The research aims to document the variability of Naples yellow pigments in selected artworks by Czech painters. Raman spectroscopy reveals significant differences in the spectra of the pigments, including the presence of hexagonal phase as the dominant phase in some samples, which is surprising considering it is generally considered a minor admixture. The findings suggest that the presence of admixtures and diverse production conditions contribute to the diversity of Naples yellow pigments and their corresponding Raman spectra, making identification challenging. The presented data can serve as a reference for identification purposes.

Summary: The reception of numerous new pigments during the nineteenth-century Colour Revolution was characterized by contrasting attitudes. Initial enthusiasm for chromatic possibilities was soon accompanied by concerns over stability and performance. This study focuses on John Ruskin, a renowned art critic and artist in Victorian England, and investigates his attitude towards pigment stability through archival research and material analysis of watercolours preserved at the Ashmolean Museum. The findings indicate his careful selection of materials based on the treatise Chromatography by chemist George Field and reveal the use of a previously unreported cobalt-based blue pigment.

Summary: Nitrates can increase the production of hydrophilic yellow pigments in Monascus ruber CGMCC 10910. Through transcriptomic and proteomic analysis, it was found that nitrates upregulate genes involved in yellow pigment biosynthesis and pathways related to pigment biosynthesis, precursor production, and transport. Proteomic analysis also showed that nitrates enhance the expression of proteins involved in HYP production. These findings provide insights into the regulatory mechanism of nitrates in enhancing HYP production in Monascus.

Summary: New blue pigments based on Ca,=-iaxAl iotas2_CoxU iotasg (x = 0-0.5) were obtained by the combustion method, without annealing. The obtained pigments have specific surface areas between 3 and 5 m2/g. As the substitution degree, x, increases from 0 to 0.5 apfu, the crystallite size of Ca iota-xLaxAl iotas2-xCoxO1g pigments decreases from 44 to 26 nm. Despite the low Co2 content (<4% mass), the pigments exhibit intense blue shades and high total solar reflectance. CIE C/a /b parameters indicate that as the chromophore content increases from 0.1 apfu (73.3/-2.6/-34.1) to 0.5 apfu (60.5/2.6/-47.0), the blue color of the pigments intensifies while the total solar reflectance decreases from 70.7% (x = 0.1) to 59.6% (x = 0.5). The tests confirmed the potential use of Ca iota-x1axAl iotas2-xCoO iotag pigments in producing cool, NIR-reflective coatings.

Summary: Through pigment metabolite analysis and comparative transcriptome analysis, the key pigment difference and its molecular mechanism of accumulation in Chinese narcissus yellow-flowered mutant compared to the white-flowered cultivars were revealed. The mutant had a significantly higher total carotenoid content and exhibited opposite gene expression pattern in the carotenoid biosynthesis pathway compared to the white-flowered cultivars, which likely contributed to carotenoid accumulation in the mutant's tepals.

Summary: Raman analysis is utilized to study the phases observed in the different colored enamels of French and Chinese objects from the 18th century. The effectiveness of a solid-state spectroscopic approach and a multivariate chemometric approach is compared. The incorporation of spectra from similar phases in the literature is crucial for obtaining quality results. The combination of visual observation and multivariate analysis reveals that different production techniques result in variations in the peaks associated with the main As-O stretching vibration. Arsenic-based opacifiers are detected in the enamelled artifacts, both in French and Chinese objects.
