Abstract
Redeposited copper, only once previously reported in connection with prehistoric and early metals, was found in the course of metallographic analysis of two bronze axes in the Newbury Museum. The first axe, although conventionally flat, was probably produced in a bivalve mould, and had been hot and cold forged in the process of raising the flanges and hardening the cutting edge (hardness figures: 187 and 156 at cutting edge, 103-115 elsewhere). Redeposited copper was visible in several of the sections. The second axe, with widely splayed blade and decorative grooves, showed a large area of rede posited copper on the longitudinal section; on a transverse section the same phenomenon was associated with porosity. Hot or cold working with intermediate annealing was shown by the metallographic analysis; but the axe had not been submitted to work-hardening, perhaps because it was not intended for use (hardness figures: 103-7 at cutting edge, 101-110 at butt). It was probably cast in an open mold, with the grooves added afterwards by grinding. -- AATA
