Electrochemical phase speciation of corrosion products on bronze works of art and archeological pieces
Electrochemical techniques have recently found some interesting applications in the qualitative and quantitative analysis of cultural heritage metal objects. These methods applied to analysis of corrosion products on bronze artwork and archeological objects are complicated by the simultaneous occurence of solution and solid state reactions, electrochemically driven ion insertion and metal dedeposition. An electrochemical method of cyclic voltammetry of micro-particles (CVMP) attached to a carbon paste electrode for phase speciation of microsampled corrosion products is demonstrated on two characteristic examples of long-term air and subterranean formed patinas. Patina constituent phases are identified by comparing electrochemical parameters of the patina samples to those of reference compounds. An identification scheme is suggested which may be applied to discern the various corrosion products of bronze based on CVMP electrochemical data. Comparison of CVMP to ATR-FTIR results reveals that the methods are complementary and that their simultaneous application could prove particularly valuable in drawing conclusions about the current state and prospects of conservation and restoration of bronze artefacts.
