It wasand I was looking at some baseball memorabilia on eBay when I saw the following posting: "Please see my other auctions, including vaseline glass! I saw a piece of yellow-green glass in one photo and another photo of the same piece of glass that was taken in a dark room with a UV blacklight. It was bright neon green!
The nickname "vaseline" comes from the resemblance of some pieces to the hue of Vaseline petroleum jelly, which is light yellow in color. The yellow color of a piece of vaseline glass can actually vary to the naked eye under different light sources. But to purists, it must fluoresce bright green under a blacklight or it doesn't qualify. Vaseline glass is also called "uranium glass," at times, and for good reason.
One mark is a bee insect with the letter H on the left wing, the letter I on the body and the letter G on the right wing. This mark was used by Higbee Glass, in operation ca. The other mark, an outline of the state of Ohio with the letter M, is the present day mark used by Mosser Glass Company of Ohio.

This is referring to the basic color of vaseline glass and does not take into account various forms of decoration. The addition of the Uranium Dioxide makes the glass color yellow-green. When this is done, the glass turns a bright florescent green! Not all yellow-green glass will turn florescent green when a UV light is shined on it.

The European definition describes vaseline glass as any kind of creamy yellow glass shading to white with a colour that resembles the original vaseline ointment. In experiments with uranium as a glass colourant were being carried out by Whitefriars Glass Works in London and in a pair of uranium glass candlesticks were presented to the Queen. Also in the 19th century, Davidsons glass produced a glass called pearline that contained uranium and was made with heat sensitive chemicals that turned milky white when reheated, producing a shading effect from yellow to milky white at the edges. American collectors consider any kind of glass which glows under ultra-violet light because it contains uranium, as vaseline glass.
