In 2006-2009 a part of a Roman period settlement dated to the 2nd - early 5th century AD was excavated in the cadastral area of Cerekvice nad Loučnou (Pardubice Region, Czech Republic). The recovered material seems to be quite common (barbarian pottery), but it also contains a surprisingly rich collection of imports from Roman provinces (a sword tip, Roman provincial pottery, parts of bronze vessels).
Amorphous bronze shapes, prismatic ingots, and a fused fragment of a bronze vessel might be indicative of local re-smelting of bronze objects. The manufacture of crushers is documented as well.
In addition to other raw materials, they were manufactured of quartzitic porphyry which had to be transported from central and northwestern Bohemia.
