Techniques of silversmithing in the Sasanian Hormizd II plate were examined using microscopy, radiography, metallography, electron beam microprobe and x-ray fluorescence. Results show that the plate was made from a silver sheet hammered from an ingot, that relief was created by removing metal from the background, that chasing was used for fine lines, and that sixteen separate inserts form the high relief. The foot was applied by soldering. Mercury gilding was applied selectively.
