English: A historical reenactment showing a craftsman using traditional double bellows to heat a charcoal forge. Next to the anvil and hammers, small ceramic crucibles (likely tempered with sand or crushed ceramics to withstand thermal shock) are visible. In the 11th century, such tools were essential for melting non-ferrous metals like bronze or silver, often using the lost-wax casting technique. The scene reflects the specialized metallurgical skills present in major early medieval centers in Poland and across Europe.
