“…In order to obtain maximum results without missing cases of double dyeing, which was a very common practice in ancient times [7,29], we used two extraction methods in the course of the study for each of the samples (each sample was divided into two subsamples). The first method used mild extraction that was done using formic acid, a weak acid that preserves the glycosidic linkages and provides good extracting ability.…”

Early evidence (late 2nd millennium BCE) of plant-based dyeing of textiles from Timna, Israel

In this article, we focus on the analysis of dyed textile fragments uncovered at an early Iron Age (11th-10th centuries BCE) copper smelting site during new excavations in the Timna Valley conducted by the Central Timna Valley (CTV) Project, as well as those found by the Arabah Expedition at the Hathor Temple (Site 200), dated to the Late Bronze/early Iron Ages (13th-11th centuries BCE). Analysis by HPLC-DAD identified two organic dyestuffs, Rubia tinctorum L. and indigotin, from a plant source (probably Isatis tinctoria L.). They are among the earliest plants known in the dyeing craft and cultivated primarily for this purpose. This study provides the earliest evidence of textiles dyed utilizing a chemical dyeing process based on an industrial dyeing plant from the Levant. Moreover, our results shed new light on the society operating the copper mines at the time, suggesting the existence of an elite that was interested in these high quality textiles and invested efforts in procuring them by long-distance trade.

“…The most separations have been done using columns packed with 3 or 5 μm particles. Recently, UHPLC with sub‐2 μm particles was also applied . A comparison of HPLC and UHPLC columns for the separation of flavonoids and anthraquinones showed that the latter provided better resolution, higher peak capacity, and lower LODs, while maintaining the same reproducibility (RSD below 1%) .…”

High-performance liquid chromatography plays an important role in analysis of historical organic colorants. A number of papers have been published in this field over the last 30 years. Classification of the most commonly used natural dyes and an overview of high-performance liquid chromatography methods with main focus on recent works (2008 to the beginning of 2014) are provided. The review deals with an entire analytical protocol covering sample preparation, chromatographic separation, and suitable detection (UV/visible and fluorescent spectroscopy and mass spectrometric techniques). High-performance liquid chromatography has been successfully used in the complete characterization of some organic dyestuffs present in historical and art objects. The possibilities and difficulties for identification of natural sources of historical colorants are also discussed.

“…A great variety of inorganic and organic components can be found in works that have relevance for cultural heritage. For this reason, several advanced analytical approaches have been successfully employed for such investigations, including spectroscopic, immunological and chromatographic techniques. Since ancient times, organic pigments and dyes have formed an essential part of a wide selection of artists' materials that have been extensively used for colouring textiles and on paintings mainly for glazing purposes.…”

In the present work, a new substrate is proposed for the surface‐enhanced Raman spectroscopy (SERS) analysis of samples, which are of cultural heritage importance. A new and simple procedure is presented for the preparation of a stable SERS‐active substrate. It is based on the photoreduction of silver nitrate by ultraviolet light utilising hydroxypropyl cellulose as stabilising agent. The substrate's characteristics were tested and compared with a known substrate: a citrate‐reduced silver colloid, with alizarin as a reference material. Using the new substrate, it was possible to positively detect the organic dye alizarin red S, and two organic pigments: madder lake and alizarin crimson dark, as well as organic colourants prepared in paint layers with different organic binders without an interfering signal arising from the media, and without sample pre‐treatment. Furthermore, the investigated substrate also shows promising characteristics for the analysis of the cross sections of the samples because of its viscosity and the possibility of maintaining better control of the application of the substrate to the layer of interest.
