Title: Green Uranium footed bowl ID = Davidson 718
Post by: Fen on June 26, 2011, 08:46:42 AM
When I bought this I didn't think by looking at it that it was Uranium glass, though I am very often surprised one way or another. It has a definate glow under the UV light but it's a muted and rather yellow glow, could it be Cadmium? Also any ideas on its origin would be appreciated. I have trawled the "search" facility but have given up. The diameter is nine inches. Many thanks in advance.

Cadmium gives a distinct yellowy orange glow without a hint of green. The glow from this bowl is probably caused by the use of manganese, which was used as a decoloriser, but don't ask me why it's found in coloured glass.

Your bowl is a Davidson 503 bowl. This bowl was introduced in 1956 but the pattern on it dates from 1898 (Stewart and Stewart). It is not found in uranium glass.

Thank you, Manganese, I have learned something today, that's really good.

More examples in different colours in this thread, seems to be some confusion over the pattern number though: http://www.glassmessages.com/index.php/topic,27827.0.html

718 is the 1898 pattern, which was reused in the flat rim 504 shape in 1956.

There has been a request to update the titke of this thread with a "504" ID for this bowl, and also for items in the message that John linked to above. However, in the linked to message, there is another linked message (http://www.glassmessages.com/index.php/topic,1990.msg13657.html#msg13657) which refers to "718".

Can we please confirm things.
Is the bowl in this thread definitely a "504"?
And are the items in the messages linked to not "718" but also "504"?

Hi,

It is a Davidson 718 bowl. This bowl was introduced around 1935. The pattern on the bowl is the davidson 1890 pattern.

I've got my numbers in a twiddle. Isn't this bowl part of the 503 fruit set that was based on the 718 aka 1898 pattern, at least that's the way I read your book p 60

Hi,

No the 503 is a different pattern.
