A methodology for dating archeological lead artifacts based on the
voltammetry of microparticles is described. This methodology is based on the comparison of the height of speci¿c voltammetric features from PbO2
and PbO corrosion
products formed under long-term alteration conditions. Calibration of the method was
performed with the help of a series of well-documented lead pieces from the funds of
di¿erent museums of the Comunitat Valenciana (Spain) covering from the ¿fth century
B.C. to present day. The variation of peak currents with the time of corrosion can be¿tted
to the same potential rate law as that found by Reich (R = 0.070 ( 0.005), using
measurements on the Meissner fraction in the superconducting state of lead. The
proposed electrochemical methodology enables the dating of archeological lead artifacts
with a time-dependent uncertainty estimated to be (150 years for the most ancient
samples in this study
