EVAPORITES OF THE WADI NATRUN: SEASONAL AND ANNUAL VARIATION AND ITS IMPLICATION FOR ANCIENT EXPLOITATION*Archaeometry - Tập 46 Số 4 - Trang 497-516 - 2004
Andrew Shortland
The evaporitic deposits of the Wadi Natrun on the edge of the Western Desert of
Egypt have been used in variety of crafts and industries for over 6000 years.
This paper reviews the formation processes of the evaporitic deposits between
the different lakes in the wadi and for the wadi as a whole. It shows that the
precipitation of sodium carbonate minerals within the lakes is seasonal and

A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome, Italy)Archaeometry - Tập 57 Số 2 - Trang 269-296 - 2015
Cristina Maria Belfiore, Giusj Valentina Fichera, Mauro Francesco La Russa, Antonino Pezzino, Silvestro Antonio Ruffolo, Giuliana Galli, Donatella Barca
This contribution focuses on the study of historical mortars from a Roman
archaeological site known as Villa dei Quintili, a monumental villa located in
the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar
samples, collected from several edifices within the complex. A multi‐analytical
approach, including polarized optical microscopy, scanning electron microscopy
coupled w... hiện toàn bộ
ROMAN AND MEDIEVAL GLASS FROM THE ITALIAN AREA: BULK CHARACTERIZATION AND RELATIONSHIPS WITH PRODUCTION TECHNOLOGIES*Archaeometry - Tập 47 Số 4 - Trang 797-816 - 2005
Alberta Silvestri, Gianmariο Molin, Gabriella Salviulo
Compositional investigations were performed on 81 Roman and medieval glass
fragments (first to 14th centuries ad) from four Italian archaeological sites.
The samples were soda–lime–silica in composition, with natron as flux for the
Roman and early medieval glass samples, and with plant ash as flux for the late
medieval ones. The varying colours are due to the differing FeO, Fe 2 O 3 , MnO
and Sb 2... hiện toàn bộ
MAKING COLOURLESS GLASS IN THE ROMAN PERIOD*Archaeometry - Tập 47 Số 4 - Trang 763-780 - 2005
Caroline Jackson
This paper discusses the compositional analysis of Roman colourless glass from
three sites in Britain. The findings suggest that two broad compositional groups
can be identified on the basis of the choice of the initial raw materials
selected for glass production, in particular the sand. The largest of these
groups is inherently different from the naturally coloured, blue–green glasses
of the same... hiện toàn bộ
THE ANALYSIS OF SECOND MILLENNIUM GLASS FROM EGYPT AND MESOPOTAMIA, PART 1: NEW WDS ANALYSES*Archaeometry - Tập 48 Số 4 - Trang 581-603 - 2006
Andrew Shortland, Katherine Eremin
A recent analytical study by SEM–WDS was carried out on 226 glasses from the
Late Bronze Age, analysing each of the glasses for a total of at least 22
elements, the largest such analytical study conducted on these glasses. The aim
of the analysis was first to identify which elements were brought in with each
of the raw materials and, second, to accurately characterize those raw
materials. Since di... hiện toàn bộ
The origins of Byzantine glass from Maroni Petrera, CyprusArchaeometry - Tập 44 Số 2 - Trang 257-272 - 2002
Ian C. Freestone, Matthew Ponting, Michael Hughes
Nineteen glasses from Maroni Petrera, Cyprus, dating to the sixth–seventh
centuries ad, have been analysed by energy‐dispersive X‐ray analysis in the
scanning electron microscope for major and minor elements. A subset of 15
glasses was also analysed for trace elements, using inductively coupled plasma
mass spectrometry. Two groups are identified. The majority is made of glass
produced in the coast... hiện toàn bộ
THE PROVENANCE OF OBSIDIAN ARTEFACTS FROM THE WĀDĪ ATH‐THAYYILAH 3 NEOLITHIC SITE (EASTERN YEMEN PLATEAU) BY LA–ICP–MSArchaeometry - Tập 54 Số 4 - Trang 603-622 - 2012
Donatella Barca, Giulio Lucarini, Francesco Fedele
The geological sources of obsidian in the Red Sea region provide the raw
material used for the production of obsidian artefacts found in prehistoric
sites on both sides of the Red Sea, as far afield as Egypt, the Persian Gulf and
Mesopotamia. This paper presents the chemical characterization of five obsidian
geological samples and 20 prehistoric artefacts from a systematically excavated
Neolithic ... hiện toàn bộ
