Resumen: Artificially patinated artistic bronze was exposed to the action of 0.10 and 12.68 ppm SO2 contamination in the laboratory at 100% relative humidity. The surface layers were characterized using electrochemical, atomic absorption, X-ray powder diffraction techniques and Fourier transformÐinfrared spectrometry. Thermal and calorimetric studies were also performed. Some of the compounds identified were cuprite (Cu2O), digenite (Cu1.8S), yarrowite (Cu9S8), chalcocite (Cu2S), brochantite (Cu4(OH)6SO4), bonattite (CuSO4 á3H2O) and Sn2S3.
