A second mechanism is Solarization.

A second mechanism is Solarization. Solarization is perhaps the most widely known effect of optical radiation on glass. Solarization was reported as early as 1930. (Stockbarger 455.) Solarization is the coloration that occurs in optical glasses, when ultraviolet radiation causes ionic contaminants in the glass to reach a more positive state.(Gliemeroth 67.) Common contaminants are cerium, iron, manganese, europium, arsenic, and antimony. The stability of the ions in this more positive state is difficult to predict.

第二種機制是日曬。日曬可能是在玻璃上的光輻射的最廣為人知的效果。日曬報導早1930（斯托克巴傑455）日曬是發生在光學玻璃中，當紫外線輻射使離子污染物，玻璃中的著色達到一個更積極的狀態。（Gliemeroth 67.）常見污染物是鈰，鐵，錳，銪，砷和銻。離子在此更積極的狀態穩定性是難以預料的。
