Topic: Cased Glass Rose Bowl Id Help Needed

[Bernard C]

Selenium oxide is a fairly standard colorant for red/pink glass   ...

Christine — Yes, but it's the first time I've seen any mention of selenium in relation to Victorian coloured glass.   For example there's no mention of it in the Webb recipes in Hajdamach.

Here's a reference to selenium from 1899:

That is interesting, though, that Walsh was using it that early.  Do you remember if there was cadmium in the mix?  If it's a struck color maybe that's why it's so variable.  Did they make it for long?  Perhaps it was too difficult to control.

I was reading Hadjamach wrong before.  Bernard's right that he meant it was shaded by heat.  Sure would be nice to see the ad he mentions to see how it's described/shown.

...   Bernard, could you show us your Crushed Strawberry pieces?

Unnecessary for this topic, as there is at least one image already referenced above, and there are two more examples here.   Further examples are in both Reynolds and Gulliver.

Well for that matter this whole discussion of heat-sensitive glass is unnecessary for the original topic.  Thank you for the link.  I was hoping to see the variation in color you mentioned, but it's not important and it's off-topic, so nevermind.

(BTW, the blurb in that link about patent 5286, just under the Crushed Strawberry photo is very interesting - sounds a lot like graal.)
