hi, hope someone can help me with the origin of this hunk of bright emerald green glass, this is not my area of expertise. Looks like a frosted glass dog sitting on a clear glass base. No marks found. Thanks for any info!
I agree with EstateAntiques, that it's probably Uranium glass, but It's not "Vaseline". Vaseline glass is a shade of Yellow glass and not green .
Here's a link to verify my last statement.
Vaseline Glass and Authenticity
People often use the black light test thinking it guarantees authenticity. It is not a reliable test to show glass is old. Any glass which was colored with uranium salts will glow. Some very old clear glass glows; some does not. Most depression era green glass will glow but you will find later glass that glows too.
The other confusion is with the term ” Vaseline glass”. Originally Vaseline referred to a glass color, light yellow, not bright yellow and not green. This light yellow glass glows green under black light. Often today people use the term “Vaseline” to refer to any green or yellow glass that turns green under ultraviolet light. Besides the green and light yellow glass there is some cranberry or opalescent glass that turns green. A good book on the topic is Vaseline Glass: Canary to Contemporary by David A. Peterson
