2025, 1723 - Real Manufactura de Vidros em Coina (1723)

The most famous Portuguese royal glass manufacture, and chronologically the first successful one was established in Coina, a small town close by the Tagus left bank opposite to Lisbon but a little further north. Earlier, since 1670 there were various failed attempts of establishing a manufacture of glass promoted or supported by the Crown, the later of these in 1714 under the direction of Giovanni Pallada a Venetian glass master from the Low Countries. Until now it was not known when this glass manufacture started production and the only reference to the date of its establishment was an indirect one in an anonymous travel book published in Amsterdam in 1729 that said that the King had established it 10 years ago so that the year 1719 come to be accepted without apparently any further research on the matter as the year when that manufacture was actually established.
Since, this time, the attention of the Crown was turned to France for help with the necessary technology transfers the authors further researched this matter from both ends, France and Portugal, and could find some interesting information regarding the convoluted process behind this endeavour that involved espionage and attempted sabotage, something that may also be of interest to elucidate similar situations and procedures both in Portugal and in other countries.
Finally, it could be found beyond doubt that glass was melted for the first time in this manufacture in May 1723, a fact that may bring the reappraisal of a few attributions of glass pieces in museums.

The excavations at the oasis and ancient settlement of Tayma (Saudi Arabia), amid the ancient incense trade route, revealed numerous prestige goods such as metals, incense, and glass. Of over 180 glass fragments found in late Iron Age to Islamic contexts, 101 are the focus of the investigation, which aims to identify their provenance. Were these locally produced glasses, or were they acquired through supraregional trade networks? The presence of glass in Tayma for several centuries, both in residential and public contexts, has led to various interpretations of the objects. In this regard, the place and time of deposition of glass fragments will be analyzed by placing them within their archaeological framework, including stratigraphic context, distribution, and chronological classification. For the archaeometric investigation, the non-destructive portable energy-dispersive X-ray fluorescence analysis (p-ED-RF) was employed. All 101 glass fragments underwent chemical characterization to assess their composition and production techniques. The combination of archaeological and chemical classification allows the interpretation of the glass fragments as common commodities, material versus exchange value, and prestige goods. The acquired data sets the stage for an area frequently demonstrated as an intersection in the commerce paths between major entities. However, this area provides implications for understanding the distribution and trade of glass artifacts across Egypt, Mesopotamia, the Mediterranean, and the Arabian Peninsula.

The Islamic era left a lasting legacy in the visual and material culture of the Iberian Peninsula. This phenomenon is particularly striking in a rare find of architectural fragments of an arcade with horseshoe-shaped arches in the Convent of Santa Fe in Toledo (Spain). Different coloured glass inlays (turquoise, purple, colourless) were embedded in the iconographic bas-relief made of plaster, an artistic technique that is unparalleled. This study explores the dynamics of glass supply and workshop practices in 11 th-century Spain through the chemical analysis of 46 specimens of these glass inlays. Laser ablation inductively coupled plasma mass spectrometry revealed a compositional resemblance but no identity with Iberian sodarich plant ash glass, pointing to a regional or even local production. The glass assemblage as a whole proved very homogeneous and we were able to identify possible batches in which the individual pieces were probably cut from the same sheet of glass. Despite using the same base glass, the copper-turquoise coloured fragments showed different colouring techniques and combinations of colouring elements. Our findings shed light on the organisation of secondary glass working and material procurement for artistic purposes in Islamic Spain.

The systematic chemical analysis of large collections of archaeological glass beads is essential to better understand trade patterns at different times around the world. Glass beads' trade towards and within sub-Saharan West Africa grew exponentially over time to culminate with the establishment of the Atlantic Trade. Although these artefacts are very commonly found in archaeological contexts dating after the 15 th century CE, the assemblages are generally poorly studied from a chemical point of view. We present here the study of 916 glass beads found in five archaeological sites in Ghana, Mali, and Senegal, in contexts dated between the 15 th and the mid-20 th century CE. Besides the techno-stylistic classification of the whole assemblage, the compositional study of a subgroup of 578 monochrome and polychrome glass beads was performed. The 798 glass samples composing the selected beads were therefore classified based on their main chemical composition. Moreover, major, minor, and trace elements analysis by Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) and the statistical analysis of the results by Principal Component Analysis (PCA) led to the identification of the probable origin of the glass. Different suppliers were distinguished for the Ghanaian earlier beads and the Senegalese and Malian later ones, in relation to the different European trade partners at different times.

Between 2001 and 2004, the roadside and customs station of Romula, which is mentioned in Ancient
Roman itineraries, was excavated at the site of Ribnica near Brežice on the Aquliea–Emona–Siscia road.
The more significant part of the settlement, the remains of the Roman road, and the western necropolis with 131 graves were uncovered. At Ribnica, as at several other burial sites in south-eastern Slovenia
and north-western Croatia, four graves were discovered, containing eight house urns altogether. House
urns are predominantly found in the richer graves, which is reflected both in the grave architecture itself and in the grave goods. The time span of the burials with house urns at Romula ranges from the midfirst century to the end of the second century. Regarding form, decoration, and method of manufacture, the house urns from Ribnica cannot be fully compared with finds from other sites, such as the
nearby Dvorce near Čatež, Drnovo, or Draga near Bela Cerkev. They seem to be most closely related to
those from Veliki Kamen and to the Bela Krajina specimens from Rosalnice or Borštek near Metlika,
although even in these comparisons, many differences can be noted.

This article draws attention to the glass found in Gujarat, a region of India that, until now, has been poorly studied as far as this material is concerned. Glass objects from Vadnagar, including beads, bangles, fragments of containers and glass wastes were analyzed to obtain their elemental and isotopic compositions, with the goal to determine places of glass production and reconstruct trade networks. Dating for the glass material ranges from the 3rd c. BCE to the contemporaneous period, providing an opportunity for a diachronic approach. Results show a wide variety of glass types, including glasses manufactured in South Asia (India and Sri Lanka) and glasses imported from the Mediterranean area and later from the Middle East via Indian Ocean routes. This study sheds light on two recently discovered Indian glasses: types m-Na-Al 7 and m-Na-Al 13. Type m-Na-Al 7 is heterogeneous and not yet clearly defined, while type m-Na-Al 13 is a local production of Gujarat with a diffusion that seems to have been limited to the immediate region. The diversity of glass types identified at Vadnagar testifies to the dynamism of the trade conducted in the region and of multiple connections, with ramifications sustained over very long periods of time, throughout South Asia and the Indian Ocean trade network.

Summary – Caoline & Co. – bead separators.
A small and simple thing – a glass bead. Easy to make: heat an iron rod, heat glass, wind hot glass around hot rod. Let the bead cool down. And now: try to get it off the rod. If the rod (mandrel) is thick and tapering – no problem, the iron shrinks while cooling. So does the glass, but a small fraction less than the iron. The bead loosens from the rod. But if the rod (i.e. the hole-to-be) is thin – then the glass bead will stick. Forever. To make a wound bead with small holes, the mandrel needs to be coated with a seperator: a special substance to prevent the glass from sticking to the rod. The author has started some years ago on a quest in search of a bead separator, which leaves little trace and which contains only "prehistoric" ingredients (as opposed to modern professional bead separators). She has supplied herself with a plethora of different substances and began mixing, stirring and testing. Some results are presented here – and some recipes for the use of fellow bead-makers. That's important: 1. The wet separator has to coat the cold mandrel. It has to stick. 2. Ditto when dry. 3. The coating has to stick and stay even and smooth while the mandrel is heated – no crumpling. 4. Heat-resistant up to 950 °C minimum, the more the better. No spouting of glowing particles. 5. The hot glass has to adhere, no slipping off. 6. No let-go while working the hot glass. 7. Easy let-go of the ready cooled-down bead. 8. No corrosion of the mandrel (modern separators are optimized for stainless steel, not bronze-age materials). 9. The bead maker has to get hold of the substance without too much ado. 10. The separator should not be too poisonous.

2025, KRATKA POVIJEST PROZORSKOG STAKLA // A BRIEF HISTORY OF WINDOW GLASS

Completely flat and optically perfect window glass, which we use most often today and consider the standard in the design of living space, is the result of a very long and intensive process of experimentation. The first attempts to shape glass window panels were recorded as early as the 1st century BC, but mass production and use began in the first half of the 1st century. Despite the great upheavals in the development of new glassmaking techniques, primarily the technique of blowing, it seems that the casting process was extremely important in the production of window glass for centuries after oth- er techniques of shaping were perfected. Blowing window glass is more intensively practiced only from the 3rd-4th centuries, equally by using the “cylinder” and “crown” techniques. Only the pre-in- dustrial period of the 18th and part of the 19th century brought more drastic changes in the order of popularity of separate production techniques, so the crown technique, as the least profitable in eco- nomical terms, was almost completely abandoned, and the cylinder blowing and casting techniques prevailed in the overall production of window glass. This was made possible primarily by various innova- tive mechanisms that “extended the life” of historical techniques, but did not stop the process of the upcoming complete automation of production, in which everything is ultimately left to the machine.

Yaşamın her alanında görebildiğimiz cam tıpkı seramik ve metal gibi ateşin hayat verdiği sanatlarından birisi olarak bilinmektedir. Üretildiği ilk çağlardan itibaren günümüze kadar cam üretimi gelişerek devam etmiştir. Erken dönemlerde insanların süslenme ihtiyacını karşılayabilmek adına yapılsa da daha sonraki dönemlerde aydınlanmada kandil ve pencere camı, mobilya aksamlarında süsleyici öğe, tıp alanında ilaç kabı, mutfaklarda yaygın bir sofra kabı gibi gündelik hayatı kolaylaştırmak için üretildiği görülmektedir. İlaç kabı, kozmetik, içki kabı, servis vb. amaçlarla kullanıldığı bilinen bu cam eserler antikçağ boyunca farklı formlarda karşımıza çıkmaktadır. Zengin form çeşitliliğinden oluşan cam eserler özellikle MÖ 1. yüzyıldan itibaren üfleme tekniğinin ortaya çıkmasıyla artış göstermiştir. Özellikle serbest üfleme tekniğinin keşfi ile toplumun her kesiminde kullanılan cam günlük yaşamda da karşılaşılan bir malzeme haline gelmiştir. Cam üfleme tekniğinin ortaya çıkışı ile birlikte cam formlarında da çeşitlilik artmış ve daha az zamanda daha çok kap üretilebilmiştir. Şanlıurfa Müzesi'ndeki cam şişeleri konu alan çalışma kapsamında cam eserler üzerinde incelemeler ve değerlendirmeler yapılarak antik dönem cam şişelerin kullanım şekilleri hakkında bilgiler verilecektir. Satın alma yolu ile müzeye kazandırılan 5 adet cam şişe sağlam durumdadır ve serbest üfleme tekniğinde yapılarak aletle şekillendirilmiştir. Yeşil ve kobalt mavisinin kullanıldığı şişeler form ve bezeme olarak incelendiğinde Geç Roma dönemine tarihlendirilmektedir.

The article publishes a small collection of finds from the Roman period with a possible overlap into the Migration period. All the finds come from metal detector surveys conducted in the area between Hradec Králové and Jaroměř between 2012 and 2023 (Fig. 1). The published finds complete our knowledge about the settlement of this area. They also provide additional pieces for the mosaic of contacts between the East Bohemian region
and the Roman provincial and East Germanic environments. This small collection of finds consists of a total of 12 objects from 9 locations dating from the B1a phase to the Late Roman period, with a possible overlap into the Migration period. These were mostly so far unknown sites or locations from which Roman period finds had been unknown. In the case of a heat-deformed fibula from Skalička nad Labem (Fig. 2:2), we believe that, in this
case, the metal detector survey resulted in the discovery of a hitherto unrecognized cemetery from the 1st century AD. Products of Roman provincial workshops from the Danube environment are also, to a lesser extent, represented in the assemblage (Fig. 2:3, 4). Next to them, there are also objects which were perhaps manufactured in local Barbarian workshops, but by craftsmen from the East Germanic cultural circle (Fig. 2:5, 6, 9).

În ultimii ani, în cadrul şantierelor arheologice din Târgovişte, dar şi în zonele din proximitatea fostei cetăţi de scaun a Ţării Româneşti, au fost documentate in situ o serie de artefacte din sticlă, din perioada secolelor XVI-XVIII. Majoritatea cercetărilor s-au realizat în ceea ce se poate numi aria de influenţă a unor lăcaşuri de cult medievale, deci în necropolă sau incintă, unele vase fiind descoperite întregi, altele permiţând restaurarea. Istoriografia privind sticla medievală din spaţiul românesc şi, în special, contextul arheologic al descoperirii acesteia în zona Munteniei, a pus problema utilizării vaselor de sticlă ca o practică funerară în perioada secolelor XIV-XVIII. Acest obicei a fost confirmat şi în Târgoviştea medievală şi premodernă prin recentele descoperiri şi, implicit, prin documentarea exactă a contextului arheologic. Cercetarea depozitelor de arheologie ale Complexului Naţional Muzeal "Curtea Domnească" din Târgovişte a scos la lumină şi alte fragmente de sticlă, inedite, acestea provenind din mormintele situate în diverse necropole ale oraşului medieval. Scopul acestui material este de a face cunoscute aceste noi contribuţii arheologice privind sticla funerară din Târgovişte, oraş care până în momentul de faţă lipsea de pe harta descoperirilor de acest fel.

Glass finds from the archaeological excavations of the city of Istakhr in the Fars province (actual Iran) have been subjected to archaeometric analysis. Based on their archaeological context, these pieces were dated to the fifth century CE. The glass fragments were analysed using environmental scanning electron microscopy combined with synchrotron-based X-ray fluorescence to accurately assess their chemical composition and fingerprint. Based on the results, the objects are categorised as high "sodium-lime-silica" with plant ash used as a flux. Based on the chemical composition, which reflects the production of glass, the objects were divided into three separate groups; however, the raw materials remained almost the same during the heyday of Istakhr.

Les forêts de Compiègne et de Retz ont abrité entre le XIVe et le début du XVIIe siècle un important artisanat de fabrication du verre, qui tirait profit de leurs multiples ressources (bois, sable, fougères). Mentionné par les anciens historiens et chroniqueurs du Valois (Bergeron, Carlier, ...) cet artisanat, dont la micro-toponymie1 conserve encore le souvenir, n'avait jusqu'alors pas fait l'objet d'une recherche systématique2. Une série de dépouillements de certains fonds d'archives conservés aux Archives Nationales et aux Archives Départementales de l'Oise a permis de localiser et dater certains des fours à verre, et d'identifier les dynasties de verriers les ayant fait fonctionner. Ces travaux ont également mis en lumière certains réseaux familiaux et réseaux techniques de fabrication du verre, dont la zone d'influence dépassait largement le Valois.

This study concerns a «window» of approximately 40 km ², opening on to two different landscapes : the lower Doubs Valley and the Bresse plateau, both very humid zone. The interaction of man with his environment is studied from Antiquity to the Middle Ages by comparing archaeological evidence of human settlements with paleoenvironmental reconstruction of land dynamics. There is dense occupation throughout all periods, which proves the attractiveness of the area. However, local factors, both natural and anthropic, seem to have influenced spatial implantation along the river. Bresse attenante, soit une zone très marquée par l'humidité. Il corrèle les données issues de la prospection archéologique et de la démarche paléo-environnementale pour appréhender, par étapes historiques et sur la longue durée, le rapport de l'homme à son milieu. La zone connaît une occupation du sol très dense dans toutes les périodes, ce qui prouve son rôle attractif. La variable réside dans les choix opérés par le peuplement. Ceux-ci sont dictés moins par la «grande histoire» que par des phénomènes locaux, physiques (évolution de la rivière) et surtout humains.

The present interdisciplinary study examines the glass tesserae from the apse mosaic of S. Sabina , part of a wider research project on Early Medieval wall paintings and mosaics in Rome. The tesserae in different green shades (pale green, green and dark green), the sole remnants of the original mosaic now lost and replaced by 16th-century frescoes, were analysed using various techniques (OM, SEM-EDS, EPMA, XRPD) to identify raw materials and production technologies, aiming to date the mosaic (5th, 9th, or 12th century AD). The analyses identified various glassy matrices, comparable to known compositional groups such as 'Roman', 'HIMT', 'Foy 2.1 , and 'Foy 3.2 , as well as opacifiers/pigments like lead antimonate and lead stannate. These results indicate that the green and most pale green tesserae were specifically produced for this mosaic. The dark green tesserae show greater variability, suggesting the reuse and recycling of preexisting materials. The archaeometric analyses support a dating between the 5th and 9th centuries AD, aligning with art-historical assessments. The comparison with the 5th-century AD counter-façade mosaic of S. Sabina revealed significant differences in the composition of the glass matrices and opacifiers/pigments, indicating that the counter-façade mosaic was primarily made from reused tesserae. Comparisons with green tesserae of other Roman mosaics highlighted a general trend of recycling and reusing tesserae, except for the 7th-century AD S. Agnese fuori le mura mosaic, where newly produced and reused tesserae coexisted. These data reinforce the hypothesis of a 5th to 9th-century AD dating for the S. Sabina apse mosaic, providing new insights into the production and use of glass tesserae in Late Antique and Early Medieval Rome.

Despite differences in shapes, sizes, and colours, some European glass vessels from the 16th and 17th centuries share similarities in decoration. They are covered in intricate diamond-point engravings of fine lines forming floral and foliage motifs, scroll, foliate, and spiral borders, and occasionally, birds, people, and animals. Many of these vessels are attributed to glassworks in Austria (1570–1600) although several other workshops used similar elements in their engraved decorations. Six sites are introduced here to identify the potential engravers of 23 fragments with comparable decorations from Finland, Estonia, and Latvia. Variations in design and dating are described and addressed.

Inside the boat investigated twenty years ago in the “Parco di Teodorico” at Ravenna there were several glass objects placed in contact with the hull and inside the planking. In addition to these category of material, there were also potteries, wooden and leather objects. For their characteristics and for quantities present, such glass objects could constitute a nucleus for commercial purposes coming from the Near East and the Mediterranean oriental area. The glass and other materials found in the boat date to the 5th century A.D.

Chemical analyses of Merovingian beads from the cemetery of Lent-Lentseveld, Zeitschrift für Archäologie des Mittelalters 50, 27–78 (Verlag Dr. Rudolf Habelt GmbH, Bonn)

In this article a method with which chemical groups of beads from a single Merovingian cemetery can
be distinguished is explained and tested. In short, this is accomplished by chemically analysing the complete
glass bead assemblage of the 6th-century cemetery Lent-Lentseveld with both pXRF and LA-ICP-MS, and
using Principal Component Analyses (PCA) to identify chemical groups per bead-type and per grave. The
results are very promising: for imported bead-types from the Eastern Mediterranean and further East clear
chemical groups per bead-type are recognised, and for both imported and European beads distinct groups per
grave are identified. These findings suggest that in the 6th century beads were imported over long distances
to Lent on several occasions, and that once strung, beads tended to remain together as a distinct set. The
beads excavated in Lent were clearly not acquired or exchanged one at a time, which opens up the possibility
that complete strings of beads were exchanged. In future research it will be interesting to establish whether
the same patterns can be recognised for bead assemblages excavated from other Merovingian cemeteries in
the region.

Ciacova is located on the course of Timișul Mort, an old branch of the Timiș River, which served as the main course during the medieval period. The town is located 28 km southwest of Timișoara, in the Timiș Plain, part of the Banat Plain, at an average altitude of 80 meters. Archaeological research in the area began with systematic excavations led by Alexandru Rădulescu in 2000 and 2006, followed by preventive campaigns between 2013 and 2022. The findings include tableware, construction ceramics, metal objects, coins, and ceramic pipes. The most significant campaigns, conducted in 2015, 2017, and 2018, have been well documented in specialized literature. One of the most notable artifacts discovered is the large number of tiles used for stove construction. Approximately 80 fragments or complete pieces have been analysed, with 33 having uncertain identification. These tiles are categorized and subcategorized, playing a key role in archaeological research, despite often being misclassified or overlooked in broader studies. These findings provide valuable insights into the cultural and technological evolution of medieval Ciacova, although some results from the initial excavations in 2000 and 2006 remain largely unknown.

The quality of Dorflinger glasswork showcases the work of nineteenth-century artisans who utilised copper and stone wheels to cut quality glass to a high degree of perfection and stunning beauty. Christian Dorflinger (1828-1915) was creating fragile things of beauty from the elements of the earth in a process of transmutation that culminated in a final, singular, purified, and translucent substance we know as glass. By its very definition, fine glass-making is a transformation in progress, where raw materials are collected, refined, mixed, and then heated. So it is with any alchemical transmutation, be it spagyric or philosophical, since what is sought is the spirit within the material, to make it at once useful and beautiful alike.

n 1872, the master glassmaker Carl Lange from the Schierbach glassworks in Nienstädt in what was then Schaumburg-Lippe intended to set up his own glass factory in Stadthagen. In the building application he wrote to the Stadthagen town council on April 16, 1872: “ [...] for the time being only one hut will be built, employing 12 to 13 glassmakers [...]”. Who were these first glassmakers who dared to make such a new start with Carl Lange, where did they come from and what social relationships did these first glassmaking families have with each other? The author asked himself these questions years ago as part of his personal family research. The present work is intended to provide an answer.

Dating mortar from the building phase of the church ruin in the Museum Garden
Dating the subterranean remnants of a medieval church in the garden of Sigtuna Museum has proved an elusive task since first excavated in 1915. Three hypothetical datings have been presented: c. 1080, c. 1150–1160, and c. 1220. New radiocarbon dates (Ua-84213 & Ua-84214) of charcoal in lime mortar from the church’s building phase have, after undergoing KDE plot in OxCal v4.4.4. (Bronk Ramsey 2017 & 2021), established the building period to between 1020 and 1120. Hence, the hypothetical dating c. 1080 stand firm as most plausible.

The subject of this paper is a glass beaker with an inscription found in the necropolis of the Isaurian city of Philadelpheia. It bears the inscription "katakhaire kai euphrainou" in ancient Greek, a motto that can be translated as "Rejoice and be merry". It was found, along with numerous other vessels, during a rescue excavation conducted in a refuse heap in the necropolis of the ancient city of Philadelpheia, situated north of the village of Gökçeseki in the Ermenek district of Karaman province. The glass beaker from Philadelpheia, of which other examples of its type are documented in the literature, appears to be the only example so far discovered in Anatolia. It is dated to between the 2 nd half of the 1 st century AD and the beginning of the 2 nd century AD. The "motto" or "phrase" on the glass expresses good wishes. This must be intended for "wishing good health" to those who were served drinks in these vessels. The beaker was produced using the mould-blowing technique. It is decorated from below the rim to the lowermost part of its body with horizontal and vertical floral and geometric motifs in relief. The inscription is in the main frieze on the body. The glass was blown into a two-part mould. The similarities in decoration, height and width between this glass and the ones found in Syria indicate a Syrian origin for this glass, which is the most commonly suggested origin for this type of beaker.
