In central Europe, amber artefacts of HaC–D1 date are found most abundantly in the areas of Greater Poland, central Silesia, Bohemia, and Moravia. Upper Silesia and western Lesser Poland are very poor in finds of this type. The paucity of amber finds in the Częstochowa-
Gliwice area cannot be explained by the cremation of the deceased together with their furnishings, as biritual rites prevailed there during the Hallstatt period and inhumation burials predominated over cremations. Other factors (possibly fashion or customs) that influenced the rare furnishing of the deceased with amber ornaments must therefore be taken into account.

The cemetery has not been previously known in the literature. Only two small earthen vessels have survived in the hands of private owners till the present day. Their dating can be only broadly placed within the range extending from Bronze Age IV to Hallstatt D.

The earliest examples known from excavations in central Europe are dated most often to the BrB-HaA1/A2 phases of the Bronze Age (= BA II-III/IV); they are made of high magnesium glass (HMG), which is now most frequently corroded. In the HaA2-HaB3 phases (= BA IV-V), beads were produced of a "mixed alkali" glass, also called low magnesium and high potassium glass (LMHK), which is usually preserved in rather good condition. The oldest beads are large as a rule, well made, using, at least in some cases, the folding technique. Small, undecorated beads made of "mixed alkali" glass were produced by the winding technique.

Gebhard and to the Group 11b according to the typology by th.e. Haevernick. the chemical composition of all three glasses was tested using the la-icP-ms method. based on the content of k 2 o and mgo, the discussed materials can be classified as low magnesium glasses (lmG). thanks to the discovery of the fragment of the glass bracelet, the settlement episode of the la tène culture can be dated to lt c1b, possibly to lt c2. key words: racibórz, the la tène culture, glass bracelet, tests on the chemical composition of glass lidia kamyszek, luiza kęPa, tomasz Purowski, barbara waGner, leszek ŻyGadło

A subsample of 18 of these were additionally subjected to analysis by means of LA–ICP–MS in order to validate the results obtained by EPMA. Some glass was made using mineral soda and some using plant ash rich in sodium. Both high‐magnesium soda–lime glass (HMG) and low‐magnesium soda–lime glass (LMG) were identified. A large number of samples are characterized by low MgO content and medium K2O content (LMMK glass), combined with low concentrations of CaO and high Fe2O3 and Al2O3. All the LMMK glass contains numerous silica crystals and inclusions composed of a number of elements (most frequently Cu, Co, Sb, As, Ag, Ni and Fe). The LMMK glass was presumably made in Europe during the Hallstatt C.

The group of analysed specimens consists mostly of beads but includes also one glass inset for a brass ring and one glass ring. The glass of 37 them was subjected to the chemical composition analysis (35 beads, the inset and the ring). The chemical composition analysis was conducted using mainly EPMA (Electron Probe Micro-Analysis) and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) methods. In total, 182 analyses were performed using both methods.

The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 BCE). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K2O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.

The beads were tested with the EPMA method. Altogether 65 measurements were made. In terms of morphology, the artifacts are all the same, but they differ in microstructure and chemical composition. For some a mixed alkali flux was used, for others soda‐rich plant ashes. Even so, all of the beads seem to have been made from local raw materials in central Europe (soda‐rich plant ashes could have come from plants growing near one of the mainland salt sources, which are frequent, for example, in south‐eastern Poland).

Two beads have good formal parallels from territories associated with Mycenaean culture. The material of which they were made combines features of the previously distinguished groups A and B of Mycenaean faience. The faience discovered in Poland ties it in with faiences of group A by the use of soda-rich plant ashes as a fluxing agent, whereas a similar cobalt ore colorant links it to group B. The other two beads were made most probably in Egypt, considering the use of a similar alkali raw material (halophyte plant ash) and an alum (source of cobalt) as colorant in one case. The beads must have reached the territory of Poland from the Eastern Mediterranean most probably through Italy and up the so-called Amber Road.

The grave is dated to the Bronze Age IV (HaA2-HaB1; about 1150/1100-1000/950 BC). A typological (formal) analysis of the beads and an examination of the chemical composition of the glass in two cases (by the LA-ICP-MS method) indicated the north Italian workshops as the most likely place of their production. From there they reached Małopolska (Little Poland) by the "Amber Route".

56 glass samples from 52 beads found in Poland at 13 archaeological
sites (mainly cemeteries). The artefacts have been
dated to the II–V period of the Bronze Age (=phases BzB–
HaB; c. 1600–750/700 BC). The LA-ICP-MS method was
applied. Two groups were distinguished in this assemblage
based on a comparison of the MgO to K2O ratio in glass: (i)
high magnesium glass (HMG)—23; and (ii) low magnesium
and high potassium glass (LMHK)—33 (29 matrix glass specimens
and 4 decorative). In southern Poland, beads made of
HMG and LMHK are often found in the same cemeteries.
Analyses have shown that HMG was most probably made in
Mesopotamia and that at least one cobalt glass is of Egyptian
provenance. LMHK glass was made in Europe, most probably
in Italy. Also, Italy was the most probable transit point for
artefacts made of HMG en route to East-Central Europe.

The analysis involved 48 samples from 39 objects. The main objectives were: (i) to characterize the glassy faience in terms of the physical structure and chemical composition of the glass; (ii) to evaluate differences in the chemical composition of the glass forming the glassy faience; (iii) to examine the chemical composition of the true glass in the decoration on objects made of glassy faience. Glassy faience was found to be made of glass and numerous quartz grains, inclusions and gas bubbles. Manifest in the true glass of the decoration were numerous minor inclusions of the colorant, represented mostly by a compound of lead and antimony. Two groups of glass forming glassy faience were distinguished based on the differences in chemical composition: LMMK and LMG GF . The first is characterized by a moderate concentration of K 2 O (average 2.7%), high Al 2 O 3 , Fe 2 O 3 and some trace elements (e.g. B and Ti). The second has a generally lower content, compared to LMMK, of K , but a large amount of PbO and Sb 2 O 5 . All of the glasses had a low content of CaO and MgO. LMMK glass was melted using sand and a flux that could not be easily identified (plant ash?), whereas LMG GF and LMG glass used sand and natron. The glassy faience is usually blue and was colored with cobalt compounds. The yellow glass of the decoration was colored with lead antimonate.

The obtained results indicate that the low magnesium glass (LMG) from which the biconical bead is made was melted from good quality silica (quartz pebbles or “pure” sand) and mineral soda. It is not certain whether the calcium component was added separately. The glass was coloured with iron compounds. On the other hand, the high magnesium glass (HMG) used in the body and two layers of decoration of the ‘eye’ bead was produced from poor quality sand (strongly contaminated) and plant ash. The separate addition of the third component, namely the calcium, is not likely in this case. Black glass owes its colour to the presence of iron compounds, white glass – to phosphorus compounds, while light blue glass – to copper compounds (copper compounds were contaminated with those of arsenic and silver). As compared with LMG glass, samples of HMG glass are marked by a higher content of oxides of potassium, magnesium, aluminium, and the majority of trace elements.
The results of physico-chemical examination have demonstrated that the glasses from Modlnica (especially HMG) find close analogies among the 7th-6th century BC materials known from the North Pontic zone. The difference lies in the application of phosphorus compounds to achieve the white colour in Modlnica (in all such glasses previously known, the colour was given by compounds of tin or antimony). The studies on the technology of manufacture of glasses used in the beads from Modlnica, as well as the formal analysis of these artefacts, suggest that they could have been brought to Małopolska from the east.
