A study was made of the colors produced by platinum, palladium, and rhodium when they were introduced as their chlorides in alkali silicate, borate, and phosphate glasses. Yellow, pinkish‐yellow, orange, and brown colors in addition to aventurines and grays were observed in the various glasses. Platinum exhibits an interesting behavior in phosphate glasses. Small additions of platinum chloride produce gray colors, whereas larger amounts produce yellow and orange colors. Nucleation by platinum crystals leading to devitrification was observed in some phosphate glasses.
