Uranium Glass, also known as Vaseline Glass, derives its distinct color from the addition of uranium oxide during the glass-making process. This type of glassware gained popularity in the late 19th and early 20th centuries.Context
The most reliable way to identify the presence of uranium in the glass is to expose it in the dark to a source of ultraviolet light (e.g., a black light). If the glass glows a rich green color, it contains uranium. This green fluorescence explains why an example of Vaseline glass that looks yellow under incandescent lighting might take on a greenish tinge when viewed outdoors.Made/Created
