Inside out: Fusing 3D imaging modalities for the internal and external investigation of multi-material museum objects
3D imaging methods are increasingly employed in cultural heritage research to analyse and document objects in museum collections. In this work, we provide an interactive visualisation plugin for the open-source software Blender, to combine and inspect two complementary 3D imaging modalities: CT images, which capture the interior; and surface scans,... -

Changes in the production materials of Burmese textiles in the nineteenth century - dyes, mordants and fibres of Karen garments from the British Museum’s collection
The materials of six Karen textiles from the British Museum’s collection were investigated with the main aim of studying the production changes over the course of the nineteenth century and how these changes related to local and colonial trade networks. The textiles span chronologically from the 1830s to the early...Tamburini, Diego ; Dyer, Joanne ; Cartwright, Caroline ; Green, Alexandra

First evidence and characterisation of rare chrome-based colourants used on 19th-century textiles from Myanmar
First evidence for the use of the chrome yellow dyeing method was obtained on late 19th-century Karen textiles from Myanmar. Non-invasive observations obtained by digital microscopy and fibre optic reflectance spectroscopy (FORS) provided hints of the possible presence of non-conventional organic colourants in yellow, orange and green threads used to...Tamburini, Diego ; Dyer, Joanne ; Cartwright, Caroline

Studying Saraha: technical and multi-analytical investigation of the painting materials and techniques in an 18th century Tibetan thangka
Scientific analyses of the traditional materials and methods in thangka production are uncommon, as thangkas are sacred objects, the sampling of which is discouraged, in order to preserve their integrity. This study builds on this important ethical challenge and presents a three-stage methodology that systematically delves deeper into each layer... -

Fibre optic reflectance spectroscopy and multispectral imaging for the non-invasive investigation of Asian colourants in Chinese textiles from Dunhuang (7th-10th century AD)
The archaeological complex of Dunhuang (northwestern Gansu, China) is considered a pearl on the Silk Road and the content of its caves revolutionised oriental studies. The British Museum hosts a significant number of textiles and textile fragments from the site. Although mostly catalogued and studied from the point of view...Tamburini, Diego ; Dyer, Joanne

Bordering on Asian paintings: dye analysis of textile borders and mount elements to complement research on Asian pictorial art
Mount components and textile borders represent important elements of Asian paintings. However, they are often side-lined or not considered an integral part of the original piece, as they may be later additions or may have been replaced during historic conservation or mounting interventions. Nevertheless, evidence is sometimes present that textile...Tamburini, Diego ; Dyer, Joanne ; Heady, Teresa ; Derham, Alice ; Kim-Marandet, Meejung …

A multi‑scalar investigation of the colouring materials used in textile wrappings of Egyptian votive animal mummies
Commonly exhibited in museum galleries, animal mummies have been the focus of interest of both visitors and researchers alike. The study of these animal remains not only provides new insights into embalming techniques, but also brings a unique perspective on religious, social and economic practices. Twenty animal mummies are discussed...Tamburini, Diego ; Dyer, Joanne ; Vandenbeusch, Marie ; Borla, Matilde ; Angelici, Debora …

Ancient encaustic: An experimental exploration of technology, ageing behaviour and approaches to analytical investigation
The composition of the ancient wax-based painting technique known as encaustic has long been the subject of debate. Ancient sources provide few details of the technology, and modern understanding of the medium is restricted to theoretical interpretation and experimental observation. In this multi-analytical collaborative study, a number of analytical approaches...Stacey, Rebecca J. ; Dyer, Joanne ; Mussell, C. ; Lluveras-Tenorio, A. ; Colombini, M.P. …
