Fluorescent ZIRCON SAND CONCENTRATE Foote Mineral Co

ZIRCON SAND CONCENTRATE Foote Mineral Company, Philadelphia, Pennsylvania I don’t know the origins of this item and have never seen one like it before. It is a glass jar about 3.5 inches tall and 2 inches wide filled with zircon sand concentrate, which is fluorescent! The old looking label reads “Zircon sand Conc. lot 7838 Foote Mineral Co., Philadelphia, PA Chemical Division. It is heavy and weighs almost 1 pound.
