Topic: What do I have? Possible Mt. Washington?

[shannonlamp]

I am seeking help identifying this art glass lamp shade.  I believe it is from an early gas or perhaps kerosene hall fixture.  It has been suggested that it may be Mt. Washington, maybe Burmese or Peachblow.  Any help would be appreciated. It measures 10" high and is about 8" wide at the flanged end.

Hi, & welcome to the GMB.
If you have a black light, shine it on the shade & if it glows green then it's Burmese. Burmese, whether by Mt Washington or Thomas Webb & Sons, contains uranium & thus glows green under a black light.
Peachblow is a disputed term. A lot of glass manufacturers made glass of this colour scheme, it was very fashionable in the late 19th century. Different firms used different names for this colouration, but collectors & dealers tend to think of all pink shaded glass is Peachblow.
The Mt Washington Peachblow has a pale bluish-grey tinge at the base of the item, shading through to pink. Peachblow by Thomas Webb has a warmer, more reddish pink shading. Wheeling Peachblow is quite orange in tone shading to a reddish-brown. These are just a few examples of different versions of this colour!
There is a book devoted to Peachblow glass, written by Johanna Billings, that examines this type of glass in great detail.
At the moment I can't give an exact attribution. The colour looks like it shades pink to light yellow, which suggests Burmese, but a black light will confirm it.

Thanks for the information.  I have tried the black light and it does not glow the green color, so we have ruled out Burmese.  Any other help or suggestions would be appreciated!  I've attached a picture with a black light bulb inside the shade.
