Although medieval alabaster sculptures might appear white at present, they were colourful once, because painting and gilding the stone was an integral part of their production. This work presents the study of polychrome remnants on a selection of fourteenth century English alabasters, using multiple scientific methods (microscopy, spectroscopic and chromatographic techniques). The range of pigments identified include vermilion, red ochre, red lead, kermes, verdigris, copper resinate, azurite, lead white and carbon black. Some sophisticated decorative techniques were also observed, namely the application of translucent glazes on top of raised gilded motifs. The analysis was useful in understanding the degradation processes undergone by some materials, such as verdigris. The use of oil as binding medium for the application of the paint layers and a mordant gilding technique were determined. These findings yielded important clues towards the digital reconstruction of the original appearance of the polychrome surface, which is also presented here.

“…Han et al . recently developed a two‐step process whereby fibre dyed with R . cordifolia was initially extracted with DMSO and then subsequently extracted with an aqueous 0.5 m oxalic acid: water: acetone: methanol (1:30:40:30, v/v/v/v ); the two fractions were then combined.…”

“…Recent research by Han et al . , using soft extraction techniques, for the first time applied ultra high performance liquid chromatography (UHPLC) coupled to both Photodiode Array detection (PDA) and Electrospray Ionisation Mass Spectrometry (ESI‐MS) for chemical characterisation. Whilst the technique shows promise, it was unable to resolve completely major carboxylated components (munjistin and pseudopurpurin) typically observed in various Rubia species.…”

Natural dyes in madder (Rubiaspp.) and their extraction and analysis in historical textiles

Textiles coloration using extracts from the roots of various madder species (Rubia spp.) has been performed for centuries. To date, 68 anthraquinone colorants have been detected in Rubia spp. used to dye textiles. Many of these dyes are sensitive to hydrolysis and degradation from enzymes, extraction chemicals and processing temperatures, and are often overlooked as colorants in historical textiles. Conclusions in literature of the past 30 years concerning colorants present in planta and, particularly, in madder‐dyed artefacts are being challenged as new analysis methods are developed. The recent advent of ‘soft’ extraction techniques has demonstrated that anthraquinone glycosides and other sensitive molecules, such as carboxylated compounds, need to be preserved; this valuable chemical information embedded in the dye structure may be lost if extraction and analysis is too harsh. Some compounds thought to be present in madder and madder‐dyed artefacts are in fact degradation products resultant from the extraction process, and degradation pathways have been developed to better understand the reactivity and stability of these compounds. Detailed analysis of dyes in textile artefacts can reveal important cultural and heritage information concerning historical textiles relative to the specific dye species, the area of the world where this may have grown, how and where it was dyed, and, perhaps, where it was traded. Understanding the precise molecular structure of these dyes and their chemical reactivity is important to provide knowledge of their interactions with physical substrates, such as textile fibres, which could be used to develop superior techniques for analysis of artefacts.

“…9 This biological source identification is usually performed using high performance liquid chromatography (HPLC) with photodiode array (PDA) detection, but more recently UPLC-MS/MS and GC-MS techniques have been employed. 5,[10][11][12] Although studies have identified various components from the heartwood, 13 the principal colourant in brazilwood species is obtained from brazilin (1), which when oxidised produces the chromophore brazilein (2). In practice, when analysing historical objects the colour has often faded and consequently the amount of brazilein (2) or related homoisoflavonoids detected in the extracts of brazilwood-containing samples is generally very small.…”
