Popis: Roman glass found at Jalame, in Western Galilee, and dating from the fourth century A.D., shows a variety of colors ranging from aqua blue to green to amber. It was found that the glasses are quite reduced and that the colors arise from absorptions by Fe2+ and a ferri-sulfide chromophore. Small amounts of colorless and purple glass, which had been oxidized by adding MnO2, were also found.
