Abstract

Biocolourants have been investigated as alternatives to synthetic dyes. However, natural origin per se is not a label of harmlessness and research needed obtain safe We studied the cytotoxicity extracts from fungal (

One objects from elite Samdzong 5 tomb complex is composed wool fabrics to which copper, glass beads attached probably constitutes decorative headwear, may have been gold/silver mask....

Abstract The objective of this study was to evaluate the use micro‐Raman spectroscopy as a non‐invasive vibrational spectroscopic technique applied examination wool samples, which may be textile materials cultural heritage interest. In work, selection were primarily investigated in their unaged states through utility natural reference together with selected samples dyed different colorants, namely woad, weld and madder. identification main modes vibration fibre keratin assessed all aided...

Red is undoubtedly one of the principal colors in Iranian carpets. During twentieth century, a golden era for carpet production and export industry, madder was still primary constituents red dyestuff, used according to various dyeing methods which specific Iran. Compared earlier periods, said period witnessed clear increase hues color alternation physical visual properties. We, therefore, aim get better insight into chemical properties component made it all possible—dyes. To this effect,...

Abstract This manuscript explores the potential of macro-X-ray fluorescence (MA-XRF) for non-invasive analysis heritage textiles. XRF, especially with portable instruments, is a well-known technique non-destructive examination various cultural objects. It allows elemental composition based on single-point measurements. However, large, or complex textiles require numerous points to identify materials used and correctly interpret spectra. MA-XRF takes this type research next level, as it...

Abstract Stereomicroscopy, Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM–EDS), Fourier Transform Infrared spectroscopy with Attenuated Total Reflectance probe (FTIR-ATR), High Performance Liquid Chromatography a Photodiode Array system (HPLC–PDA), X-ray Fluorescence (XRF), Zooarchaeology by Mass Spectrometry (ZooMS), and 14 C dating were applied to an assemblage of textile leather fragments that belong the collection Byzantine & Christian Museum Athens in Greece lacked...

The relationship between bibliographic and archival research, on the one hand, object-based study, other, forms a very important basis for research into historical production techniques. Several written sources provide insight recipes dyeing black in past. Yet, this does not guarantee that these are representative of an entire society or were used dyers practice. way to assess how closely practical aligned entail chemical analysis textiles. This article focuses identification ingredients dye...

Abstract Quality control of sample material (e.g. charcoal, collagen) is receiving considerable attention in the effort to obtain more reliable 14 C dates. The atomic carbon nitrogen (C:N) ratio a useful indicator contamination and/or degradation bone collagen. Wool and silk are also composed proteinaceous such as collagen, C:N may be quality for archaeological wool silk. Analyses modern undyed, mordanted, non-mordanted, naturally dyed were done order determine range that indicates quality....

Summary Using the organic artefacts from fourth‐century BC grave at Bulhakovo in southern Ukraine, this article discusses economics of perishable material culture Scythians Pontic Steppe region. Thanks to survival materials (wood, leather, textiles), burial provides important information about complex networks production and exchange that existed European Scythia. Scientific analyses produced new data regarding techniques used for wooden, leather textile objects, providing an opportunity a...

Interleaves are pieces of paper which meant to protect illuminations, illustrations, and opposite folios from pigment ink deterioration. The Dalā’il al-Khayrāt or ‘Guidelines the Blessings’, one most widespread prayer books for Muslims, was written by Muhammad ibn Sulaymān al- Jazūlī (died c.1465 CE), a Moroccan mystic Sufi. Depending on place date production, West (Morocco) East (Southeast Asia), manuscripts reflect local styles in text design cover. From sixteenth up end nineteenth...

ABSTRACT Radiocarbon ( 14 C) dating of protein-containing material (collagen, hair/wool, silk, leather) contaminated with extraneous carbon (e.g. humic substances) might result in unreliable dates when pretreated the conventional but inadequate protocols. In this study cross-flow nanofiltration was applied to pretreated, material. This method is able remove low-molecular and high-molecular weight contaminants as demonstrated previous studies. The sample quality improvement by verified...

Organic colorants of textiles found in the female burial Lieto Ristinpelto, SW Finland, were analyzed by HPLC-PDA. The textiles’ visible colors varied from different brownish shades to blueish, greenish, and reddish hues. aim chromatographic analysis was deepen current understandings dyes used Finland at transition between 12th 13th centuries AD, i.e., beginning local Medieval period, contribute important new information about clothing this less-known period textile history Finland. finds...
