Dyes in History and Archaeology 42
This is the second of the Dyes in History and Archaeology series of conference papers to be published as a Special Issue of Heritage; as before, its focus is on the use of dyes extracted from naturally occurring sources or early synthetic dyes [...]
A Study on the Degradation of Iron Gall Inks and to Preserve Them Using Green Approaches
Inks from the 12th to the 17th century were aged, and a multi-analytical approach was used for their identification based on HPLC–DAD–MS, microFTIR, and microRaman. Colorimetry analysis was also performed. After 6 years of application on filter paper, three inks were selected to be cleaned using a novel green approach based on a chemically crosslinked gel to remove unwanted materials from the ink surface. A Braga ink produced in 2018 was also tes…
Cochineal Reds in Iberia and France
The Royal Textile Factory of Covilhã, founded in 1764, is the perfect example of the Portuguese Industrial and Cultural Heritage. Despite its historical significance, comprehensive studies on the dyeing techniques employed in the 18th century remain scarce. Given the influence of French technology on Portuguese wool production, this study presents a comparative analysis of French and Spanish dyeing recipes to understand their influence on the pra…
Lac dye colours
Appreciation and prohibition shaped lac-dyeing in Europe, yet little is known. • New insights on lac dye identification can pave the way for future textile studies. • Overlooking 28 species beside Kerria lacca hinders lac dye identification accuracy. • Lac dye, lake and shellac are different and confusion leads to wrong attributions. • Clarity on lac dye’s nature and origin ensures the preservation of lac-dyed objects. Lac dye, the dyestuff deriv…
A Closer Look at Heritage Systems from Medieval Colors to Modern and Contemporary Artworks
This microreview, conducted by interdisciplinary teams, examines complex heritage material systems, such as medieval colors and modern and contemporary artworks. Our multi-analytical approach, a significant aspect of our research, is a means to this end. The conservation of works of art is our shared goal, as it ensures their accessibility and the transfer of cultural heritage to future generations. We seek to interpret the damage, usefulness, an…
A Royal Mystery
Early modern materials are not well represented in dye and mordant analyses despite extensive documentary evidence suggesting the enormous demand for coloured fabrics, even among those below the elite. Non-wovens likewise receive less attention than woven textiles despite their ubiquity in the early modern historical record. Knitted garments, in particular, have rarely been subjected to dye analysis. One garment is noteworthy for its colourfulnes…
The Colors in Medieval Illuminations through the Magnificent Scriptorium of Alfonso X, the Learned
This pioneering work studied the medieval color palette of four manuscripts produced in the scriptorium of Alfonso X, king of the Crown of Castile (r. 1252-84), including the Songs of Holy Mary (Cantigas de Santa Maria, in Rich Codex and Musicians’ Codex), Lapidary (Lapidario), and Book of Games (Libro de los juegos). Scientific analysis based on fiber-optics reflectance spectroscopy in the visible and Raman spectroscopy showed a color palette ba…
Yellow Dyes of Historical Importance
Antoine Janot and Paul Gout were 18th-century master dyers who specialised in the piece-dyeing of fine wool broadcloths manufactured in Languedoc (southern France) for exportation to the Levant. They wrote treatises, similarly entitled Mémoires de Teinture (Memoirs on Dyeing), illustrated with dozens of dyed textile samples. Janot’s is dated 1744, and Gout’s is dated 1763. These books are full of extremely valuable information, which is unique to…
Exceptional Illuminated Manuscripts at the Gulbenkian Museum
The illuminated manuscripts at the Gulbenkian Museum were produced in the 17th century, in scriptoria of the Armenian diaspora. In this work, we selected analytical methods that can be used in situ to study the colors of the illuminations. Scientific analysis based on fiber-optics reflectance spectroscopy in the visible and Raman spectroscopy has shown the use of a medieval palette based on inorganic pigments such as lapis lazuli, minium, vermili…
A First Approach to the Study of Winsor & Newton’s 19th-Century Manufacture of Madder Red Lake Pigments
This paper focuses on the first investigation of the 19th-century manufacture of red lake pigments obtained from madder by Winsor & Newton (W&N), prominent artists’ colourman at that time. The first approach to their manufacture was carried out by studying the madder entries of the company’s book P1, found in the W&N 19th Century Archive Database. Eleven production records were discovered under names such as Rose Madder, Madder Carmine, Madder La…
Yellow Lake Pigments from Weld in Art
Weld (Reseda luteola) was one of the main sources of yellow dyes used for dyeing textiles and to prepare artists’ pigments in Europe until the 19th century. For the first time, this work explores the technology of preparing weld lake pigments in the 19th century by Winsor & Newton (W&N), a renowned supplier of artists’ materials. Five recipes were discovered in the W&N 19th century Archive Database and reconstructed in the laboratory. W&N was ext…
Singing with light
A monument to Galician-Portuguese medieval lyric, the Ajuda Songbook (Cancioneiro da Ajuda) also contains an exceptional series of illuminations. Employing a multidisciplinary approach, this article uncovers the composition of the colour paints used in the Songbook, providing further insight into the circumstances of its production. It also connects the materiality of this manuscript to its economic and cultural context. Our determination of its …
