Popis:	The Agora collection of copper alloys consists of mirrors, pins and needles, lamps, vases, tools, nails and other hardware, official weights, voting ballots, sculpture, jewelry, medical instruments, weapons, and coins excavated on the North Slope of the Acropolis and in the Ancient Agora of Athens, and is housed in the Stoa of Attalos on-site. Blue, turquoise blue, dark brown, and white corrosion products on these copper alloys have been identified as a sodium copper carbonate actetate, copper (II) hydroxide, copper and tin oxide, and sodium acetate trihydrate, respectively. The analysis of the corrosion was carried out by x-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive x-ray microanalysis, and ion chromatography analysis. Conservation materials, as well as storage and environmental conditions, were found to play a role in the development of these corrosion products. Most of the objects have been chemically cleaned to various degrees...
