“…It is known that some skins were desiccated using either sodium or potassium chloride and the pH was adjusted by treating with ammonium chloride or sulphate with lime and applying potash alum [28]. Accordingly, chlorine (Cl), also omnipresent, was ascribed to the treatments above and/or to the practice of using salt for the preservation of the hides from biological attack [29]. Si may be indicative of the use of pumice powder (high in silicon dioxide, SiO 2 ) for rubbing the flesh side of the skin [30] or may arise from dirt deposition caused by ageing.…”

This paper presents the findings of the first multi-analytical investigation of the Book of Uí Mhaine, one of the largest Gaelic Books surviving from the medieval vernacular period. A combination of protein analysis, point X-ray fluorescence spectroscopy (XRF), multispectral imaging (MSI), point Fiber-Optic Reflectance Spectroscopy (FORS) and point Raman spectroscopy was used to perform a systematic investigation of the Book of Uí Mhaine’s constituent materials, including parchment, inks and pigments. The analysis revealed that the parchment was made of calfskin, both blunt tools and Pb-containing materials were used for ruling the pages throughout the manuscript, and iron-based inks were used to write the content of the book. The decoration was restricted to the initial letters and rubrication across the body text. The decoration color palette was limited to yellow and red, comprising arsenic-, mercury- and lead-based pigments. A copper-based green pigment was found only on one folio. The scientific knowledge acquired through this multi-analytical approach complemented a substantial corpus of knowledge already built by Gaelic scholars, paleographers, codicologists and conservators. This work not only allowed for the consolidation of existing information on methods and materials used for the production of medieval Gaelic manuscripts but also laid the basis for future comparative work with other contemporary traditions in Ireland and Europe.

“…Plant-based curing agents have been considered the most dominant eco-friendly curing source in academia during the last few decades. Powder, extract, and paste of different plant parts are applied to preserve goatskin for a maximum of one month [ 3 ]. The plants which were successfully investigated are Acalypha indica [ 4 ] , Semecarpus anacardium [ 5 ], Tamarindus indica [ 6 ], Azadirachta Indica [ 7 ], Cassia fistula, Psidium guajava [ 8 ] , Rumex abyssinicus [ 9 ] , Aphanamixis polystachya [ 10 ] , Sesuvium portulacastrum , Salicornia brachiata , Citrus sinensis peel [ 1 ], Clerodendrum viscosum [ 11 ], Moringa oleifera [ 12 ], Sphagneticola trilobata [ 13 ] , Acacia bussei, Acacia albida [ 14 ] , Lemon [ 15 ], Calotropis gigentea [ 16 ] , Aegle marmelos [ 17 ] , and Polygonum hydropiper [ 18 , 19 ].…”

Environmental sustainability in industrial processing is one of the most fundamental requirements for sustainable development. Leather industry is known for its vast environmental pollution. Nevertheless, green engineering may occur a paradigm shift in this sector. Plant-based goatskins curing is a cutting-edge green technology that holds the concept of pollution reduction through prevention on the upper stream of leather processing. The successful and rapid monitoring of the efficiency of this technology is the foremost demand for mass-level applications. In this study, FTIR spectroscopy was employed for monitoring the efficiency of this technology using a plant Polygonum hydropiper. Chemometrics was also applied to extract information from spectral data leading to understanding the inherent effect of studying preservatives on goatskins collagen chemistry. 10% plant-paste + 5% NaCl, 10% plant-paste + 10% NaCl, and 15% plant-paste + 5% NaCl on goatskin were assessed by FTIR on 0th, 10th, and 30th days of preservation. The Spectral curve fitting (R2 = 0.99) area of amide I and II of collagen peptide bands revealed 1.33 to 2.73 times more structural suitability of studied goatskins than control. Principal component analysis and Hierarchical cluster analysis resulted that, after 30 days of curing, 15% paste + 5% salt rubbed goatskin collagen matrix significantly (around 50%) interacted with P. hydropiper. The interaction was superficial as it happened before the opening up of collagen fibers. In conclusion, FTIR spectroscopy with chemometrics can be an effective tool in evaluating the efficiency of goatskin curing and understanding the entire effect on collagen chemistry quickly.
