Opis:
The research focuses on assessing the metal content, mainly copper, lead, iron and also silver in metallurgical slag samples from the area where historical metallurgical industry functioned. In the smelter located in Mogiła, near Krakow (southern Poland), whose operation is confirmed in sources from 1469, copper was probably refined as well as silver was separated from copper. Based on the change of chemical and soil phase content and also taking cartographic and historical data into account, considering the restrictions resulting from the modern land use the area was determined whose geochemical mapping can point to the location of the 15th century Jan Thurzo’s smelter in Mogiła near Krakow. Moreover, using the same approach with the samples of this kind here as with hazardous waste, an attempt has been made to assess their impact on the environment. Thereby, taking the geoenvironmental conditions into account, potential impact of the industrial activity has been assessed, which probably left large scale changes in the substratum, manifested in the structure, chemical content and soil phase changes. Discovering areas which are contaminated above the standard value can help to identify historical human activities, and finding the context in artefacts allows to treat geochemical anomalies as a geochronological marker. For this purpose the best are bed sediments, at present buried in the ground, of historical ditches draining the area of the supposed smelter. Correlating their qualities with analogical research of archeologically identified slags and other waste material allows for reconstructing the anthropopressure stages and the evaluation of their effects. The operation of Jan Thurzo’s smelter is significant for the history of mining and metallurgy of Poland and Central and Eastern Europe.

Opis:
The casting workshop in Grzybiany, in Lower Silesia (SW Poland) is a valuable source of knowledge on the development of casting techniques in the 7 – 6 centuries BC. Abundant evidence found on the archaeological site points to cast manufacturing by means of precision casting in ceramic moulds (lost-wax molding). The workshop is the biggest collection of moulds for bracelet, necklace and other smaller decorative artefacts in Poland. The aim of the work is to conduct the research of the moulds and casts with the view of performing a computer reconstruction of the casting moulds from the Bronze and Early Iron Age, based on the Grzybiany finds. As part of the work, both the microscopic structure and defectoscopic analyses of the casting moulds were performed. Chemical composition of the casts was tested using the X-ray fluorescence spectroscopy method. Based on these results and using computer modelling methods, a geometric visualisation was performed, which is the bases for preparing the visualisation of the process of pouring liquid metal into the moulds, reconstructing both the technology and the alloys used.

Opis:
The casting workshop in Grzybiany is one of the most important archaeological sites in regards to casting technology from the Bronze and Early Iron Ages. During the "Grzybiany. Osada nadjeziorna z epoki brązu i żelaza" [Grzybiany. Lakeside settlement from the Bronze and Early Iron Ages] research, the structure of casting moulds was analyzed as well as the chemical composition and microstructure of one of the more-interesting metal artefacts found within the workshop. Based on this, geometric visualization was performed with the help of computer-modeling methods. For scientific, experimental, and educational purposes, reconstruction of a zoomorphic pendant was performed using the lost-wax method. Wax models injected into a matrix were used, along with fired ceramic (gypsum) moulds and a specially prepared modeling alloy that corresponds to the original material. In this way, a true replica of the original was obtained: technologically, structurally and chemically. Studies of production technology of the casting workshop dated back to the Bronze and Early Iron Age help to increase the knowledge of the mould-preparing technology and the alloys used. Modern tools and computer programs aid in the research of old technologies and help disseminate the results.
Pracownia odlewnicza w Grzybianach należy do jednego z najważniejszych stanowisk archeologicznych pod względem studiów nad technologią odlewniczą w epoce brązu i wczesnej epoce żelaza. W toku prac wykonano analizę struktury form odlewniczych. Przeprowadzono także analizę składu chemicznego i mikrostruktury jednego z ciekawszych zabytków metalowych, odkrytych na terenie pracowni. Na tej podstawie, z wykorzystaniem metod modelowania komputerowego, wykonano wizualizację geometryczną. W celach naukowych, doświadczalnych i edukacyjnych wykonano rekonstrukcję zawieszki zoomorficznej przy wykorzystaniu metody wytapianych modeli. Zastosowano modele woskowe wtryskiwane do matrycy, formy ceramiczne (gipsowe) wypalane oraz specjalnie przygotowany stop modelowy, odpowiadający oryginalnemu. W ten sposób uzyskano wierną technologicznie, strukturalnie i chemicznie replikę zabytku. Badania technologii produkcji warsztatu odlewniczego z epoki brązu i wczesnej epoki żelaza przyczyniają się do wzrostu świadomości o stosowanych technikach przygotowania form i wykorzystywanych stopach. Współczesne narzędzia i techniki komputerowe wspomagają badania dawnych technologii i służą ich upowszechnianiu.

Opis:
Cast axes are one of the most numerous categories of bronze products from earlier phases of the Bronze Age found in Poland. They had multiple applications since they were not only used objects such as tools or weapons but also played the prestigious and cult roles. Investigations of the selected axes from the bronze products treasure of the Bronze Age, found in the territory of Poland, are presented in the hereby paper. The holder of these findings is the State Archaeological Museum in Warsaw. Metallurgical investigations of axes with bushing were performed in respect of the casting technology and quality of obtained castings. Macroscopic observations allowed to document the remains of the gating system and to assess the range and kind of casting defects. Light microscopy revealed the microstructure character of these relicts. The chemical composition was determined by means of the X-ray fluorescence method with energy dispersion (ED-XRF) and by the scanning electron microscopy with X-ray energy dispersion analysis in micro-areas (SEM-EDS). The shape and dimensions of cores, reproducing inner parts of axes were identified on the basis of the X-ray tomography images. Studies reconstructed production technology of the mould with gating system, determined chemical composition of the applied alloys and casting structures as well as revealed the casting defects being the result of construction and usage of moulds and cores.
