Gusums Bruk was a foundry in Gusum, Sweden, specializing in brass production. The foundry commenced operations in 1653. Chandeliers and industrial products were its main products. Cannons, copper and brass wires, button pins, candlesticks, paper fabric for fabrication, safety needles, and zippers were also made.[1] Due to the discovery of fraudulent products made by the foundry,[clarification needed] it was shut down in 1990–1991. It is no longer active, but its ruins remain.[2][3]
