A bstract This study was restricted to soda‐lime‐silica glasses which contain various agents used as decolorizers in glass, such as manganese, arsenic, antimony, cerium, and neodymium oxides and metallic selenium. The prepared glass samples were exposed to the radiation from a quartz‐mercury lamp, to sunlight, or to X radiation. Vistlal observation was supplemented by quantitative measurements of the color changes, using a General Electric automatic recording photoelectric spectrophotometer. Glasses which contain antimony discolor less readily than similar arsenic‐bearing glasses, and cerium, lead, and iron oxides in sufficient amounts minimize the discoloration due to light. Samples exposed to X radiation are usually discolored to a yellowish brown, except in the case of some cerium and iron‐bearing glasses which were practically unaffected by the same treatment. A discussion of the results and those of other investigators is given.
