SKLENÉ IMITÁCIE DRAHOKAMOV V HISTORICKÝCH ŠPERKOCH

100%
EN
Since the discovery of its production (from the Antiquity up to the Middle Ages), glass used to be a highly appreciated material. The oldest “artificial” gem in the ancient Egypt was aventurine that was imitated by glass with scattered copper dust. In jewellery, this material is still one of favourites. The effort to use glass in the most different ways led to production of various decorative materials and to imitations of precious stones as well. Glass production technology started to develop more remarkably in the 16th century. In this time glasses of various colours were produced that made imitations of natural precious stones of the whole colour range possible.

There were some fragments of glass objects found during surface surveys of the southern part of Trenčín Basin in the second half of 1990´s. The finds from Trenčianska Turná and Trenčianske Stankovce may come probably from the end of the middle ages or the beginning of modern time. The finds from Soblahov and Mníchova Lehota cannot be datable without analyses, but we can exclude their recent origin.

The Archaeological Museum of the Slovak National Museum in Bratislava realized excavations of an extinct church fort in the village of Svodín (part Maďarský Svodín) in the years 1995-2000. The first written account of the St. Michael’s church comes from the year 1291. At the beginning of the 17th century a fort against Turks was built around it. The church was destroyed in 1945. The excavations revealed the church basement with graves, the fortification base trench, remains of ossarium, the castle storing pits and parts of a castle ditch. The excavation results were published already. The finds of glass were spread over the whole excavation area. A small glass bottle was found behind the church. The pit I included a coin of Magyar King Ferdinand II. (1639), neck of a kutrolf, fragment of a glass vessel with geometric and plant ornament and fragment of a glass vessel with coloured depiction of a warrior. In the pit IV a coin of Magyar king Matthias II. (1608-1619) was found together with 23 blue glass raspberry-shaped beads. The pit VI included two legged glass cups.

Glass imitations of natural precious stones are frequently met in gemmological as well as archaeological practice. A survey of methods and approaches used for quite a precise differentiation of glass from crystalline materials is given in the article. We were oriented in non-destructive methods first of all that allow relatively exact identification.

In the collections of the City Museum in Bratislava except of functional glass articles there are also many glass objects combined with the other materials. They mainly belong to the sphere of artistic blacksmith´s and locksmith´ s trade as well as to the production of glass windowpanes. From the 2nd half of the 19th century we have dividing bars in combination of iron, bronze and glass. Two painted windowpanes from the 18th century come from the interior of the church of Poor Clares. From our later acquisitions we should mention the windowpane from the Jewish neologic synagogue built in 1893-1894 according to the project of the architect Dionýz Milch.

The article presents a fortuitous dicovery of a votive hoard of 192 ornaments made of bronze and 3 glass beads from Skorka, site 32, Krajenka commune in the southern part of Pomerania The hoard was probably deposited in the 2nd half of the Vth period of the Bronze Age. The majority of described remains one can classify in frames of the Nordic culture circle.

Chemical composition of La Tène glass from Devín castle was set by semi-quantitative spectral analysis. Considering the obtained results, all the analysed samples could be classified into the group of sodium-calcium-siliceous glass. Chemical characteristics reflect the usage of sodium flux in the glass production. Big portions of calcium (Ca) and magnesium (Mg) in the analysed samples are indicating flux obtaining from phytohaline plants fly ash, what is characteristic to Mediterranean region. Hence, the glass melt was imported. The semi-quantitative chemical composition showed particular elements, which were used as dyeing oxides. A final glass colour depended on the dyeing oxide used and the atmosphere in a glass furnace. Cobalt-blue glass colouring was caused by cobalt oxide (CoO), while paler shades were probably obtained by changed CoC concentration and higher contents of Fe2O3, PbO and Sb2O3. Dark purple shades were obtained by adding of manganese (Mn) compounds and by reduction atmosphere. Oxidation atmosphere and adding of compounds containing iron (Fe) and copper (Cu) produced olive-green colouring.

TURNOVSKÁ KOMPOZICE

88%
EN
The term Turnovská kompozice (Turnov composition) has been introduced for the coloured glasses that were used in the Turnov region for grinding of jewellery and gemstones imitating natural precious stones. The local “soft stones” as the glass compositions were called were very popular not only in Bohemia but also abroad. The latest documented find from Slovakia is represented by rosettes excavated at Levoča in 2001. The History of Glass Symposium in 2006 has classified them to be a Turnov glass composition.

Ten glass tesserae were found during the archaeological excavations in the St. Anne Chapel in 1959. The tesserae are dated into Gothic period (between the middle of the 14th cent. and the year 1541). The glass is of better quality than glass of the mosaic of Last Judgement on the St. Guy’s Cathedral dated to the 1370 and 1371 years.

This study is primarily focused on an analysis of a collection of finds from the 16th and 17th century which originate from a single site. The collection, which consists mainly of ceramic and glass containers, deserves individual attention on the grounds of the range and state of preservation of the artefacts. Only through the presentation of such collections as a whole can we reach a fuller understanding of the issues of the material culture of the early modern period. The study will examine also the possible interpretations of the site on which the artefacts were found and attempt to connect the findings obtained through analysis of the artefacts with existing information about the arrangement and ownership relationships of the site within the general context of the economic, political and religious situation in Košice in the period of the 17th century.

In the current article we present the summarized results of the recent interdisciplinary research, which was focused on the production provenance of the glass artefacts from the 9th century AC. The artefacts were found in 1960 during a previous archaeological excavation of four ovens in Nitra town. They were published many times as a proof of the existence of a glass production. Multiphase interdisciplinary analyses of glassy artefacts were subsequently published in the different editions. Here we present the results in resume and rise a discussion about the importance of these findings for the research of the historical glass and for the knowledge of the details connected with the technology of metallurgy of iron. We use a working term „glass-none glass” for the type of glass made during the iron production. This term should be understood as a contribution to the discussion on the necessity to distinguish through the verbal terms atypical to the glass production chemical compositions. These compositions have been evident for a long time among the results of the analysis of the glass beads mainly and of the other small items.

The topic of this article is basic sealing technologies of coloured glasses that were used as decorations of early medieval beads found in Slovakia and Moravia. Winding of coloured fibres around beads or application of coloured points were the most frequent ways of ornamentation. Usage of coloured cords for beads decoration is presupposed to be a new technology. It appears on so-called melon-seed glass beads („Melonenkernperlen“) from the 7th - 8th centuries as well as on olive-shaped beads dated to the 9th - 10th centuries. Intermeshing of glasses of different quality with using of a metal foil is a special way of glass sealing that was used first of all for decoration of transversely segmented beads. The glass-granulation decorated bead from Prša is a rare evidence of both the glassworker’s mastery and unusual glass sealing technology.

The article deals with summarization of existing research of medieval glass in Bohemia. It outlines a general trend within which particular research phases can be separated depending on the research intensity and items. Here is a brief specification of initial phases and detailed characterization after the year 2000. Information on recent surface prospection activities run by Ústav archeologické památkové péče (the Institute of Archaeological Monuments Care) at the central part of Krušné hory Mts. in north-western Bohemia that are focused on newly afforested areas of mountain ridges. We can find a description of surface prospection that had led to localization of three extinct medieval glassworks around the Brandov village (distr. of Most) and evaluation of recent results and defining of their contribution to the knowledge on glass production history in the Top Middle Ages.

The article is based on description and analysis of the outcomes of the experiments proceeded in the years 2004 and 2006 during that the traditional potash production technology has been restored according to written sources from the 17th, 18th and 19th centuries as well as to the experiments already done in Sweden and Poland. The authors present a wide range of chemical analysis (based i. a. on powder X-ray diffraction and XRF spectrometry) of produced spruce, beech, fern and oats straw ashes, raw and calcinated potash and emphasise its importance for the study of the history of glassmaking in the Central Europe. The most important conclusions are: differences of chemical composition between beech, spruce, fern and straw potash were rather substantial (especially higher content of CaO, SiO2, MgO, MnO and P2O5 in spruce potash and high content of SiO2, P2O5, SO3 and Cl in fern and straw potash). Burning ferns and straw for ash is much more efficient, however, especially the use of fern, as proved by the experiment, was complicated by the impossibility to obtain greater volumes of the plant in the past. The experiments have also shown that the burning temperature of wood as well as composition of soil on which the plant had grown influences the chemical composition and quality of potash; finally calcination had only inconsiderable influence on the purity of obtained product.
