According to Vaseline Glass, Inc. The government confiscated all supplies of uranium during WWII and halted all production of Vaseline Glass from approximately 1943 until the ban was lifted in Nov. From 1959 onward, glass companies began making vaseline glass again.
However, because of the expense to obtain uranium dioxide, production was and is very limited. Authentic green Depression glass was also made with uranium dioxide, but iron oxide (what we usually call rust) was also added to the glass manufacturing process to make the glass greener in color. So, green Depression glass will also glow under a blacklight due to its uranium content, but that doesn't make it vaseline glass. Serious collectors will tell you that to be vaseline, the glass has to clearly be yellow or yellow-green first, and only look vivid green under a blacklight.
That doesn't mean that some pieces of green Depression glass haven't shown up in books about vaseline glass, or that dealers won't label them for sale that way on occasion. However, those serious about this type of glass don't believe green Depression glass falls into this category.The item "RARE Vintage Double Inkwell Pen Holder Green Uranium Glass Vaseline Beautiful" is in sale since Sunday, July 12, 2020.
