An assemblage of 12 artefacts from a Bronze Age hoard was found in the Forest District of Okonek, Złotów Dstrict, Wielkopolskie Voivodeship and was subject to non-destructive testing of chemical composition. The conducted analyses show that the content of particular elements in the examined artefacts, especially copper and tin, as well as the content of additional ingredients of alloys that have an effect on their quality (lead, antimony and arsenic), is strongly varied. Based on the observed differences in the composition of bronze alloys from which particular artefacts are made, one can conclude that not all of them were produced in the same artisan workshop.

The article presents a newly discovered fragment of the Hunnic cauldron, unearthed during investment research conducted at site 59-60 in Sanok, Sanok County, Podkarpackie Voivodeship. As a result of conducted excavations, an extensive settlement from the Late Roman Period and the Early Migration Period were discovered. The fragment of the cauldron in one of the most important discoveries from here. Up to date just over 20 specimens of cauldrons or their fragments are known from Central Europe. The presented one is just the second cauldron discovered in the area of Poland. The article contains the results of stylistic, typological and chemical analyzes confirming the interpretation of this find.

The article discusses the results of interdisciplinary studies of a Romanesque stone head of high-quality artistry. It was discovered in 2017 during excavations at Nowy Targ (New Market) Square in the city of Wrocław (Lower Silesia, Poland). The sculpture originally came from one of the Romanesque sacred buildings of Wrocław, none of which have survived to this day. Although it had been made in the mid-12th century, it was found in the remains of a wooden residential building burnt down in the 14th century. The results of petrographic analyses indicate that the stone head was made of fine-grained sandstone classified as lithic wacke. The raw material was most likely a Devonian-Carboniferous sandstone from the Opava Mountains. However, similar sandstones also occurred in several medieval mines located in Upper Silesia. According to a popular belief, medieval aesthetics required such sculptures to be polychromed. The non-destructive analyses conducted with the microscopic XRF , XRD , and FTIR methods demonstrated that a clean stone surface was also acceptable.

The paper presents results of technological analyses executed on selected finger‑rings prevalently from the Stradonice oppidum. Analysed were the elementary composition of the metal parts of the finger rings; the technology employed for the manufacturing of the metal parts and for the setting of the gems in the bezels; as well as the material of the inlays.
