Technical Observations: The patina is a smooth green with some spots of red cuprite. The axe head has losses at both ends, which are corroded and therefore must have occurred before burial. Surface losses reveal a very uneven and pitted metallic surface.
The axe head was cast in two pours of metal. Due to the corrosion process, the seam where the second pour of metal was applied to the first has become visible. The sides were shaped further by hammering, probably with annealing.
