The aim of presented experiments was to select solutions of chemical compounds mentioned in publications, to be used to form artificial patina and determination of its adequate coloration on the surfaces silvered and covered with bronze. The application of elaborated recipes of solutions to form patina on completed parts of gilded and silvered parts imitates an accelerated process of natural corrosion. In natural conditions process of forming patina takes long years. One has to be very careful, while because of applying corrosive agents to the very thin foils, like 0,2 ц of silver foil, or 0,5 ц of bronze, controlling of such a process can be very difficult.
