Metal Salt Weighting of Silk
Treating silk with metal salts was a common practice starting in the second half of the 19th century until the early 20th century. It aimed to increase the weight and thickness of the fibres. However, the presence of metal salts is believed to accelerate and aggravate the deterioration of historical silk textiles, and weighted silks are nowadays considered one of the most pressing issues in textile conservation. This paper explores the history of…
LA-ICP-MS labels early medieval Tuscan finds from Siena and Donoratico as late natron glass
A Roman Egyptian Painting Workshop
Roman‐period mummy portraits are considered to be ancient antecedents of modern portraiture. However, the techniques and materials used in their manufacture are not thoroughly understood. Analytical study of the pigments as well as the binding materials helps to address questions on what aspects of the painting practices originate from Pharaonic and/or Graeco‐Roman traditions, and can aid in determining the provenance of the raw materials from po…
Characterization of 18th century Portuguese glass from Real Fábrica de Vidros de Coina
Composition and state of alteration of 18th-century glass finds found at the Cistercian nunnery of Clairefontaine, Belgium
Deeply colored and black-appearing Roman glass
Evidence of early medieval soda ash glass in the archaeological site of San Genesio (Tuscany)
Study of medieval glass fragments from Savona (Italy) and their relation with the glass produced in Altare
Manganese Staining of Archaeological Glass
During the study of a large number of archaeological glass fragments, manganese-rich inclusions in leached layers were observed in a limited number of cases. This phenomenon occurs only in black-coloured leached layers. Since the formation mechanism of such manganese-rich inclusions is still unclear, a combination of several analytical techniques was used in order to investigate this phenomenon and, more specifically, to obtain more information o…
Raw materials for medieval to post-medieval Tuscan glassmaking
Deeply Coloured and Black Glass in the Northern Provinces of the Roman Empire
In this work we attempt to elucidate the chronological and geographical origin of deeply coloured and black glass dating between 100 bc and ad 300 on the basis of their major and trace element compositions. Samples from the western and eastern parts of the Roman Empire were analysed. Analytical data were obtained by means of a scanning electron microscope – energy‐dispersive system (SEM–EDS, 63 samples analysed) and laser ablation – inductively c…
