Characterization
Artificially patinated layers
Artistic bronze
Thermal and calorimetric studies
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.
