A cranberry uranium vase and a cranberry style green bowl?
Leni:
--- Quote from: "KevH" --- I have seen some pieces with clear parts for the foot and rim or body decoration which react differently, showing no reaction for one part but green for the other :!:

Hi Kev :D Yes, I have many pieces like this! In some the rigaree alone glows brightly, in some the main body of the item also glows, but very much less. I always assumed this was due either to the amount of uranium in the mix, or to the fact that it might be one of the other chemicals, which causes a lesser reaction. But I still tend to call it 'uranium glass', 'cos I reckon it saves confusion! Sorry if it prods you to put on your pedant hat! :lol:

After further investigation the cranberry colour gets only further away. There are several varities of the European species and of course the colours are certain to vary across the range.
The colours defined as cranberry spread across a broad spectrum but I would sat that in general they all appear to be at the blue end of the red spectrun and ruby tends to the purer reds.
This site brings us back to the specifics of cranberry glass and there description of the colour gives an interesting observation that might make the definition of cranberry colour in glass clearer. http://www.exmoorglass.co.uk/cranberry.htm
--- Quote ---The rose tint of Cranberry is a distinctly English colour. Red glass was produced on the continent but in much darker, heavier colours. The secret of the Cranberry shade that the English made was that they added gold to the molten glass, as an expensive but very powerful colouring agent.

But just to add to the confusion http://www.gibraltar-crystal.com/cran_intro.html
appears to equate cranberry with ruby, or Roman Gold Ruby. :x
Back to square one :?:
Can our American membership come up with any US definitions applying to glass? Was cranberry part of the American glass companies palette or just used by collectors?
Frank:
Another Antique dealers definition:
--- Quote ---CRANBERRY GLASS. The colour of wild Cranberries, the pink is subtle but not so deep as Ruby red glass..Very popular with the Victorians for tablewares.Victorian Cranberry glass is often very fine glass, showing faults in the glass,such as trapped air bubbles..Modern Cranberry glass is still produced, the best pink is made in Bohemia...

Connie:
Cranberry glass was/is made by American glass companies. The most notable being Fenton. Fenton began making cranberry glass around 1939. Other American companies that I can think of off the top of my head that made cranberry were Pilgrim and Kanawha. When Pilgrim closed, it was said that Fenton was the only American company left making cranberry glass due to the cost of the gold needed in the formulation.
I think since then that the glass company (which I can't remember the name) that makes glass for the Sandwich Glass Museum makes small quantities of cranberry glass for the reproduction glass sold at the museum.
Glen and I had a conversation about cranbery glass, ruby glass, heat sensitive glass etc last year on this board.
In general, cranberry glass in the US is a pinky red made with gold as the colorant. Ruby Red is a deeperr red and I believe that selenium is used as the colorant.
JMHO YMMV
:wink:

Ah, but I think what Frank is asking is, did the makers call it 'Cranberry', or was that the name collectors gave to it? :?
Tiger, look at the pinched work on this vase of mine, bought as 'Victorian vaseline glass' :wink: and tell me if you think this one could be a relation of yours? http://glassgallery.yobunny.org.uk/displayimage.php?pos=-2392
The pinched pattern is different to that on all my other generic 'Stourbridge' Victorian Vaseline glass, but looks to me to be very like yours. I have always thought this one of mine was Bohemian.
It certainly doesn't contain Uranium in any great quantity, if at all, as it doesn't react noticeably under my little (albeit very weak and quite basic) UV keyring torch! The 'clear glass' (with apologies to Kevin) doesn't appear to react at all!
