| Popis: | This study reports the results of archaeometallurgical investigations performed on a complete two-part bronze casting mould discovered in the village of Elgiszewo (north Poland). The mould was part of the so-called Lusatian founder’s hoard deposited on the southern borders of the Chełmno group territory between 900 and 700 BC. The investigations involved the employment of spectral (ED XRF, SEM-EDS, X-ray)and microscopic (SEM-EDS, OM) analyses. The experimental casting of the model mould and socketed axe was carried out in this study as well. The chemical composition of the mould indicates the use of fire-refined (oxidized) fahlore scrap bronze, which could originally be composed of North Tyrolean copper fahlores. The metallographic results furthermore indicate deliberate tin abandonment by the Lusatian metalworker to maintain a thermal resistance of the mould during direct metal casting. Having analysed the results of the performed research, we can state that the mould from Elgiszewo was capable of ensuring direct casting and was in fact used by the Lusatian metalworkers for this purpose before the mould was finally deposited. |
