A vivid blue glass that contains cobalt oxide as a colorant. Cobalt glass was manufactured as early as the 2nd millennium BCE (Odgen 1982). The most likely sources of cobalt oxide were the ores from the Caucasus region and Iran. Cobalt glass manufactured in Egypt and Mycenae contains traces of zinc that is not found in the cobalt glass from Mesopotamia region (Odgen 1982).
