This study is concerned with the compositional analysis of Roman and early post-Roman glass from both domestic assemblages and the remains derived from glass working and producing sites in Britain, using Inductively Coupled Plasma Spectrometry (ICPS). Samples analysed were from glassworking waste from Mancetter (midsecond century), Leicester (third century) and Worcester (first to third centuries), glass production debris, probably manufactured from the raw materials, in conjuncton with a domestic assemblage, from Coppergate (first to fourth centuries, or possibly later), and a domestic assemblage from Fishergate (spanning both the Roman and immediate post- Roman periods). All the glass analysed was shown to be of a typical and uniform soda-limesilica composition, except for a small number of vessel fragments from York which were higher in calcium. Any compositional differences between blue-green glasses typologically dated either to the Roman or Saxon periods, were found not to be consistent. Analysis of the colourless glass showed that the majority appeared to be actively decolorized using antimony, in conjunction with apparent differences in the compositions of the raw materials, when compared to glass of the same date in other colours. Compositional differences between melted waste from Mancetter, Leicester and Worcester, were apparent, but not to an extent which allowed characterization to be successful. Analysis of glassmelting pots from Coppergate showed some high temperature glassworking (and possibly glassmaking) could have occurred. Other debris, thought to be indicative of glassmaking was also analysed and compared to the composition of the Roman domestic assemblage.

The work presented here focuses on the development of economic activities in the provinces of Thrace and Moesia Inferior (in today's Bulgaria), specifically on the problematic of glassmaking in Roman period and the Late Antiquity. In my work I have focused on the systematic interpretation of the economical development of the rural environment in a context of social, political and economic transformation during Roman rule. The second part of the work presents the glassmaking in the Roman Empire - its beginning, the development of certain technological processes and the specifics of trade activities with raw glass and finished glass products. A collection from the Roman site of Yurt-Stroyno was selected as a case study (during seasons 2012-2014) 1413 fragments of glass were found here. The main aim of the presented study is a typological analysis of the glass finds, supplemented by an analysis of the material composition of selected artifacts. Chemical XRF analyses of the material composition were applied due to clarify the chronological framework of the study group, to determine the source of raw glass for the local glassworks and to raise awareness of Roman and late antique glass in southeastern Bulgaria. 116 samples from the Yurta-Stroyno site were analysed. The selection of samples was carried...

Sporadiquement distribués en Méditerranée occidentale au début du Ier s. av.n.è., vaisselle et conteneurs en verre entrent dans les habitudes de consommation autour du changement d'ère et deviennent, en moins d'un siècle, des objets d'usage quotidien. Le littoral narbonnais, surface de contact entre mondes méditerranéens et continentaux, précocement soumis aux influences hellénistiques et romaines, constitue une zone propice à l'observation de cette mutation sans précédent de l'économie du verre. L'étude privilégie l'analyse d'assemblages homogènes, issus de contextes datés, autorisant une approche chrono-quantitative. Le corpus est composé de lots provenant de 18 sites du littoral de Narbonnaise orientale (épaves et dépotoirs portuaires, sites de consommation domestique, militaire et funéraire). La présence de productions non référencées ou succinctement sériées dans les classifications typologiques usuelles, invite à proposer un outil typo-chronologique adapté aux contextes précoces méditerranéens. L'approche transversale de la documentation permet de définir quatre faciès, représentatifs de quatre grandes étapes de l'évolution des productions et des habitudes de consommation. Si, en l'état des connaissances et en raison de la particularité des modes de production du verre, l'émergence et le développement des courants commerciaux sont difficiles à préciser, les abondants assemblages portuaires du littoral (Arles, Fos, Marseille, Toulon), mettent en évidence la place prépondérante des produits de consommation courante, voyageant comme vases-marchandises, dans la commercialisation des produits verriers en Méditerranée occidentale et le long de l'axe rhodanien. / Sporadically distributed in the western Mediterranean at the beginning of the first century BC, crockery and glass containers come in consumption patterns during the augustean decades and become, in less than a century, objects of daily use. The Narbonensis coastline, key point between Mediterranean and continental worlds, early influenced by Hellenistic and Roman culture, is an propitious area for the observation of this unprecedented transformation of the economy of the glass. The study focuses on the analysis of homogeneous assemblages, from dated contexts, allowing a chrono-quantitative approach. The corpus is constituted of batches from 18 sites from eastern Narbonensis (wrecks, harbour levels, domestic, military and funeral contexts). The presence of production unreferenced in usual typologies invites to propose a suitable typo-chronological tool for early Mediterranean contexts. A transversal approach allows defining four major stages in the evolution of production and consumption patterns. If, in the state of knowledge and because of the particularity of the patterns of production of glass, the emergence and development of trade flows are difficult to specify, the abundant assemblages from harbour levels (Arles, Fos, Marseille, Toulon), highlight the preponderance of common consumer products, travelling as goods more than as containers, in the trade of glass products in the western Mediterranean and along the Rhone axis.

The ancient glass collection of the National Museum has more than 200 completely intact and so far - beside few exceptions - unpublished vessels which encompass a wide chronological framework from the 5th century BC until the end of antiquity. The core of the collection is composed of mold-blown and free-blown glass. The analysis of the collection offers a view into the history of the ancient glass production; examples of all kinds of production methods can be found in it - from a corn-formed glass, through a glass made by sagging into a form, and up to a mold-blown and free-blown glass. A great number of various decoration techniques and styles used in antiquity are represented in the collection; also, it contains vessels from various places within the Roman Empire, as well as outside of it. The major part of the work comprises blown glass from the Roman imperial period (chapter four), both free-blown and mold-blown, and from this virtually half are unguentaria of various types. Almost all types of vessel produced in this period are found in this chapter. The vessels were ordered according to types - e.g. open shapes, closed shapes and in the framework of these types they are arranged further - according to other criteria which create other sub-groups - as for example forms without a foot or on a...
