An assessment of the validity, accuracy and contribution made by analytical techniques in the examination of Greek gold-related alloys since the publication of Methods of Chemical and Metallurgical Investigation of Ancient Coinage (London, 1972). White gold and two types of electrum, distinguished by the amount of copper present in the alloy, are defined and set in their historical and metallurgical context. The main sections treat 1) analytical techniques, 2) research, and 3) mints. The techniques include: a (destructive), chemical analysis and microsampling for atomic absorption, polarographic analysis and emission spectroscopy; b (nondestructive) SG measurements, XRF, NAA, XPS, PIXE, beta-ray backscattering, PAA, EPMA, and thermal expansivity. The main mints issuing white gold or electrum are Lydia, Ionia, Cyzicus, Phocaea, Lampsacus, Mytilene, Ionian revolt cities, Carthage and Syracuse. Researchcompleted since 1972 relates refining techniques, composition and mechanical properties of the alloys. Also included is a special treatment of the mints of Mytilene and Phocaea, the subject of some twenty-five years continuous work based on data obtained from non-destructive analysis. The last sections discuss quality control, the use of the touchstone, interpretation of types and hoard evidence. -- AATA
