Solid state electrochemistry based on the voltammetry of immobilized microparticles (VIMP) methodology is applied to a series of 80 Phoenician Red Slip samples from the archaeological sites of Motya (Sicily, Italy), Mogador (Morocco), Ramat‐Rahel (Israel), Sulky (Sardinia, Italy), Tas Silg (Malta), Pantelleria (Italy), and Cádiz (Spain), dated from the 8 th to the 6 th century BC. Upon attachment of sub‐microsamples to graphite electrodes in contact with aqueous H 2 SO 4 electrolyte, voltammetric features due to the reduction of Fe(III) minerals and the oxidation of Fe(II) ones, complemented with electrocatalytic effects on oxygen reduction and oxygen evolution reactions, provide characteristic electrochemical fingerprints for pottery samples. A consistent sample grouping discriminating between different potteries from different archaelogical sites, is obtained, all results being consistent with morphological, compositional and mineralogical data. Petrographic analysis supports the grouping, defining the manufacture and firing procedure for the different archaeological context.
