Recent archaeological excavations at the sites of Montieri (S. Niccolò Rectory) and Cugnano, in the Colline Metallifere ore district, uncovered several heaps of metallurgical wastes (mainly slag), whose detailed analysis revealed an extremely complex picture of metallurgical activities carried out in this area in the Middle Ages. Neither at the Rectory nor in the partially excavated “Foundries” within the old Montieri village, clear evidence has been found of silver extraction (such as “cupels”, crucibles or other metal fragments), suggesting that the refinement processes were conducted elsewhere.
