| Description | Havírna near Štěpánov nad Svratkou is a place of intensive medieval mining and processing of silver ores and base metals. Base-metals ores with sphalerite, galena and chalcopyrite were mined, probably also Ag-rich freibergite-galenite ores. Slags from the locality are of two types: 1) slag from Fe smelting, probably from local limonite ores; 2) slags after processing of base metals ores with silver; slags contain an unusually high amount of Pb (up to 38 wt. %). The investigated metal ingots from the locality are practically pure lead (four samples), one sample of silver and three samples of atypical Pb-Cu-Sb alloy. These samples correspond to the so-called “black copper”. |
