“…4a). Vermilion darkening has been reported both as a natural degradation occurring in paintings [39][40][41][42] and induced by laser irradiation. 14 The mechanisms and the compounds that impart this darkening are still of open debate and due to the difficulty in identifying the degradation products and the highly superficial nature of the degradation.…”

“…Some hypotheses had to be made and are further discussed below. Most of the identified pigments were commonly used at this period (Gliozzo et al 2021). Interpretation had to take into account additional peaks characteristic of surface contamination of buried and altered sculptures or due to the marble substrate (diffraction peaks).…”

If ancient written sources and the visual analysis of polychromies have recently revealed the complexity of the technique of painting on statues and their frequent restoration, the non-invasive punctual chemical analyses carried out do not allow one to access the chemical composition of the different paint layers. This paper presents the analysis of three statues from Roman Africa discussing the results obtained from this understudied territory and chronology. By combining visual observation (VIS, UVL), video microscopy and MA-XRF imaging, we propose here a non-invasive protocol to determine the chemical composition of the different paint layers. This allows one to unveil the complexity of the 'know-how' of a sculpture painter and sheds light on the evolution of the original appearance of the statues.

“…The in-depth study on fermented bio-additives indicates the presence of proteins and fats. Protein is known for its air-entraining enhancement qualities in the lime mortar and makes it durable in various climatic conditions [61][62][63]. The use of jaggery has been the most primitive way of construction, which has given excellent results in the hardening process in the matrix material [64].…”

Lime mortar has been a primary binding material in ancient mortar, and is one of the main reasons behind solid and stable constructions that remain stable even after thousands of years. The benefits of lime are innumerable: it is minimally processed and used with a lesser carbon footprint and embodied energy and, most crucially, it is a carbon absorbent. This research experiments with the strength properties (compression) of lime at 28, 56, and 100 days of air curing. The investigation studies the durability using water absorption, UPV test, and carbonation parameters after 100 days of exposure to air. The tested materials are subjected to SEM analysis to find the morphology of the reaction that takes place and the products that are formed. We also performed a comparative study of two different fermented additives by the duration of fermentation (1 day and 10 days) and two different doses of additives (Jaggery and Kadukkai) with air lime. The bio-additives were experimented with using gas chromatography and mass spectroscopy for the formation of new enriching compounds, which improved the qualities of traditional lime mortar. The formation of fat and protein in the additives was found using IS 7219-1973 (a method for the determination of protein in foods and feeds). Using the AOAC method, the presence of fat confirms the improvement in strength and durability properties. The phytochemical analysis details the alkaloids, terpenoids, steroids, phenols, flavonoids, tannins, glycosides, and saponins. Quantification of phenols and flavonoids adds to the beneficial aspects of the fermented additives. The experimental results indicate that using naturally fermented organic materials in the lime has made the structures stronger with the stable build of calcite and vaterite components. The self-healing capacity of lime mortar makes it time resistant.
