Presentation
Analysis and Imaging in Heritage Science (Chaired session)
This session is focusing on innovative applications of micro-analysis and imaging technologies to study objects from cultural heritage. We would welcome contributions on the use of SEM, µCT, confocal microscopy but also X-ray based techniques to study museums and archaeological objects. The session could include technical challenges of combining diverse...Ball, Alex ; Troalen, Lore G

Analytical approaches to Egyptian goldwork
The structure and composition of ancient gold objects retain information about their long history of manufacture, from the exploitation of the ore to the finishing touches, as well as evidence of their use, deposition, and degradation. By developing an efficient analytical strategy, it is possible to retrieve that information. This...Guerra, Maria F ; Troalen, Lore G ; Martinón-Torres, Marcos ; Lemasson, Quentin ; Moignard, Brice …

Middle Kingdom jewellery
The outstanding Middle Kingdom jewellery, entirely or partially made in cloisonné work, and often containing colourful beads of different materials to produce amazing polychrome effects and surface textures, also includes the earliest examples in Egypt of granulation. Many of these techniques are illustrated through the study of gold objects excavated...Guerra, Maria F ; Troalen, Lore G ; Maitland, Margaret ; Ponting, Matthew ; Price, Campbell …

Second Intermediate Period jewellery
This chapter presents the technological study of the jewellery excavated at Qurna, together with a few additional examples of gold pieces that are either well contextualized, or that can be attributed to the Second Intermediate Period and early 18th Dynasty based on their inscriptions. These parallels include objects that are...Guerra, Maria F ; Troalen, Lore G ; Tate, James ; La Niece, Susan ; Miniaci, Gianluca …

New Kingdom jewellery
The technological study of a small number of objects produced mainly in the 18th Dynasty provides new data that can be related, typologically or geographically, to earlier studied objects. The analysis of the jewellery assemblage from tomb 296 at Riqqa, and of earrings from different sites, provides information on the...Guerra, Maria F ; Troalen, Lore G ; La Niece, Susan ; Meeks, Nigel ; Quirke, Stephen …

Historical Textile Dye Analysis Using DESI-MS
Desorption electrospray ionization mass spectrometry (DESI-MS) is an ambient mass spectrometry technique that shows great potential for the analysis of fragile heritage objects in situ. This article focuses on the application of a recently built DESI source to characterize natural dyestuffs in historical textiles and a presentation of initial imaging...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Pests or prey? Micromammal species within an ancient anthropic environment at the Norse settlement site of Tuquoy (Westray, Orkney)
Micromammals, like rodents and shrews, adapt rapidly to take advantage of new food sources, habitats and ecological niches, frequently thriving in anthropogenic environments. Their remains, often retrieved during archaeological investigations, can be a valuable source of information about the past environmental conditions as well as interspecies interactions and human activity....Romaniuk, Andrzej A ; Troalen, Lore G ; Bendrey, Robin ; Herman, Jeremy S ; Owen, Olwyn …

Development and Application of Desorption Electrospray Ionization Mass Spectrometry for Historical Dye Analysis
A desorption electrospray ionization (DESI) source was built and attached to a Bruker 7T SolariX FT-ICR-MS for the in situ analysis of 14 early synthetic dyestuffs. Optimization using silk and wool cloths dyed with rhodamine B concluded that when using a commercial electrospray emitter (part number: 0601815, Bruker Daltonik), a...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Abstract
Application of DESI–MS for dye analysis of historical textiles
One key issue in the dye analysis field is the need to sample culturally significant objects. This issue is amplified when working with more fragile objects, such as historical textiles, where sampling is often impossible without threatening the structural integrity of the object. To circumvent the impact of dye analysis,...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Alison N, Hulme

Noninvasive Characterization and Quantification of Anthraquinones in Dyed Woolen Threads by Visible Diffuse Reflectance Spectroscopy
The anthraquinone components of the roots of various species of madder (like Rubia tinctorum L. and Rubia peregrina L.) have been used for millennia as red colorants in textiles, carpets, tapestries, and other objects. To understand the selection and preparation of dyestuffs in various cultures and historical periods, these dyes...Chavanne, Clarisse ; Troalen, Lore G ; Fronty, Isabelle Bardies ; Buléon, Pascal ; Walter, Philippe

An optimised small-scale sample preparation workflow for historical dye analysis using UHPLC-PDA applied to Scottish and English Renaissance embroidery
A sample preparation workflow for historical dye analysis based on 96 well plates and filtration by centrifugation was developed. It requires less sample and the introduced error is decreased, making it useful for culturally important objects. A sample preparation workflow for historical dye analysis requiring less sample has been developed....Sandström, Edith ; Wyld, Helen ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N
