Leni's quote about the "dispute" between Mt Washington and New England adds some interesting extra snippets to what is stated in various books. But while reading it I wondered if a basic question had been asked / answered before.
The Amberina patent was taken out by Joseph Locke for Libbey's New England Glass Company (a year after he emigrated to the US from England). But was Amberina also made, regardless of the US patent, in the UK and Europe? Or perhaps just marketed under the name, if not actually made as such?
Just wondering, really, because much glass in "UK collector fairs" that looks anything like 'red-and-amber' is usually labelled up as "Amberina", and I wondered if some may have been UK or European made.
Also, on the subject of "heat sensitive" glass (needing "striking" to achieve the result), the equally interesting thread back in April on "Bluerina Revisted", very usefully discussed this. Check it out here: http://www.glassmessages.com/index.php/topic,1247.0.html
