Technical Observations: The patina is a distinctly defined black and green, with green over the black at the edge of blade. There are also some brown burial deposits. The object is structurally intact, although stress cracks are present at the edges of the shaft hole. The surface has been altered by tool marks that expose bare metal, and the green patina may be the result of a modern chemical treatment or perhaps special circumstances in burial. The axe head was cast. Most of the tool marks on the surface appear to be modern.
