Technical Observations: The patina is a black wax over green corrosion products. Deep scratching following the wax-obscured contours may be the result of aggressive cleaning or possibly post-cast chasing. The considerable build-up of burial accretion and corrosion products still obscure modeling details. The object is a solid lost-wax cast.
