Title: Webb cut wine glasses for show, presumably heat sensitive amberina
Post by: glassobsessed on May 31, 2022, 07:43:20 AM

12 cm tall, both with acid etched mark according to Hajdamach (British Glass 1800-1914) dating to between 1906 and 1935. The bowls are a uranium glass, shading runs from pink to yellow to more of an orange at the base.

Sorry Christine, I should have left a glass of cold water for you.

When I bought them I did not think they would turn out to be as unusual as they appear to be.

wow.  Interesting glass technique as well as fabulous glasses.  Is it known that Thomas Webb did amberina?
Is it linked time wise or development wise with their Alexandrite?

Page 315 Hajdamach, British Glass 1800-1914 has a few paragraphs on heat sensitive glass and appendix 7 has some fascinating bits and bobs as well (including recipes - who knew ground slate might be used?), they run up to about 1900 in date.

Actually just a thought and a question - the glass I see as Amberina tends to be American and isn't usually uranium glass is it?

Most is not but it appears that the older amberina could be uranium. I think the more modern formula might include cadmium (or selenium?) to achieve heat striking.
