There are different definitions of what is or is not "vaseline glass,"
depending on what part of the world you are located. Our organization
uses this definition: Vaseline Glass is a particular color of
yellow-green glass that is made
by adding 2% Uranium Dioxide to the ingredients when the glass formula
is made. The addition of the Uranium Dioxide makes the glass color
Vaseline Glass is ALWAYS
verifiable by using an ultraviolet light (blacklight) on the glass
When this is done, the glass turns a bright florescent green!
Sometimes, even the most trained eye can be fooled by a piece of glass
that looks like Vaseline Glass, but will not 'glow' or fluoresce bright
green under a blacklight. Not all yellow-green glass will turn
GREEN when a UV light is shined on it. When manganese is added to the
formula (which also makes a yellow-colored glass) instead of Uranium
for instance, the end product will glow under a black light, but the
is an orange/peach color OR a lime green color that is much fainter
the bright neon green under UV light. Manganese was added to the glass
mixture to counteract the minor traces of iron that would give the
a 'coke-bottle' greenish tint to it.

Glass collectors primarily collect yellow or yellow-green glass. (A
controversy will probably go on forever regarding Green Depression
as Jay Glickman included some examples of green glass in his reference
book). Individual collectors each have their own preference as the
the exact color of Vaseline Glass collected. Most people primarily
the glass that is more toward the yellow end of the spectrum, but some
collect anything that 'Glows'. (Other glass that glows includes some
depression glass; Burmese glass - both old and new; and custard glass,
ranging from the pale off-white to the bright green. Each one of these
types 'Glow' due to the addition of Uranium Dioxide to the glass
CAN BE CONFUSING:
of the VGCI consider vaseline glass to be yellow or yellow-green
on if it is in room light or daylight). A glass dish can look
under incandescent lighting, but when it is taken outdoors, the UV of
sun will tickle the atoms, making the same piece look
Also, when a flash camera is used on vaseline glass, it will make it
more green than the eyes do, because the intense flash also 'tickles'
uranium atoms. Vaseline glass (in the USA) is defined by the VGCI
to be yellow first and glow green under a blacklight second.
countries have their own definition for vaseline glass. For
people in Australia use the words, 'vaseline glass' for any type of
that has an opalescent rim. What we consider (in the USA) to be
glass, they call citron or uranium glass. The British in the
Kingdom refer to glass that has a whispy opalescent treatment to be
glass. What they call 'Primrose Pearline' (a trade name from Geo.
Davidson & Son) is what the US collectors call 'vaseline
In Germany, they did not differentiate and call all of it 'uranglas'
it can be yellow or green, as long as it has uranium in it and glows
a blacklight. Many sellers on eBay will list green depression
under the 'vaseline glass' heading, knowing that vaseline glass brings
more money than green depression glass. True vaseline glass does
not have iron oxide added to the formula, which makes green depression
glass a separate formula, and thus, is not considered to be vaseline
Glass is not harmful, as the emissions from the glass are just slightly

a daily basis.
