A method for dating Hemoglobine‐containing archaeological samples using the voltammetry of microparticles is described. This is based on the record of the voltammetric response of such materials attached to paraffin‐impregnated graphite electrodes in contact with aqueous acetate buffer. Signals attributable to the Fe III /Fe II iron couple and their catalytic enhancement in the presence of H 2 O 2 can be correlated, via first‐order reaction kinetics, with the time of aging of the samples. The method has been applied to the study and dating of the polychromed architectural decoration of different parts of the architectural complex of the Longshan Temple in Lukang (18 th century, Taiwan).
