The use of manganese in glass is to mask or neutralize the greenish color imparted to the glass by the protoxide of iron. Manganese imparts to glass a pink or red tint, which being complementary to green, neutralizes the color and permits the glass to transmit white light. However when exposed to UV light  and ion exchange between the iron and the manganese molecules changes the observed color of the glass to a purple color. In the early 20th century, changes in manufacturing processes, as well as more pure batch materials, dictated different ways to decolorize glass, and the use of manganese oxide for this purpose dwindled around 1920 so we know this bowl is from the early years of rexall (1903-1920)
The spoon measures 8 inches. It reads the rexall Store on the handle. The back side is stamped 1877 N F Co (Niagara falls Co)
