The twelve areas chosen had the following characteristics: • relatively compact and sufficiently visible gilding • gilding clearly covered with black alterations • alteration both exposed and not exposed to rain • zones with geodetic lines • alterations where rainwater converged • alterations in the insides of castings Washing was carried out with standard methods, using 100 ml fractions of FIGURE 3.

This possibility seems unlikely. First, the transformation of basic copper carbonates and sulfates into copper sulfides requires the presence of sulfate-reducing bacteria and a humus-rich anaerobic environment. This condition is certainly not fulfilled in layer 1, which is sandy. Second, one would expect to see granular sulfide layers in the metal cross sections and not compact ones, which adhere closely to the metal. 3. Copper sulfides were formed under anaerobic conditions and subsequently oxidized to basic copper carbonates and sulfates.
