Paul S: I was not suggesting that your product was part of the Gay line by Webb. I was just suggesting as to why your glass was the color that it is (i.e. mega-dose of uranium). I have glass from 1840 up to 1990 that is (generically) "honey amber uranium". Boyd Crystal Art glass once made this color and there are several little novelty shapes that they made, including (ironically), a honey pot ! (I have one.). I have cut glass and pressed glass through the years that show this color. Pukeberg Glass made several shapes and designs from 1915-1930, including their 'FAN' design. One of the colors that they used was a honey amber uranium. Boyd Glass, Thomas Webb, WMF (Germany) and Steuben all had utilized various shades of that color. I have no clue who made your piece, and only decided to write to let you know that it was not some other added ingredient (like manganese) that was responsible for this coloration.
Below is a cut & etched goblet I never identified that I no longer own (someone made me an offer I could not refuse), that is a very dark amber.
Also, a open salt cellar (with cut rim) from about 1840s, and a WMF vase (label still intact), and the little dog in the WMF photo is a piece of Boyd Glass. ALL show different shading of honey amber uranium, all glow tremendously.
The patent I described earlier? ONLY uranium was used as a coloration. No manganese or other ingredients added.
