Hi,
Assumption, eh? Very dangerous thing when it comes into contact with glass :shock:
Perhaps the merit about glass is that much of it is
not marked and much of it does
not conform to prescribed parameters. It seems that when characteristics are attributted to a given company
that is when the trouble starts :shock:
Never make assumptions, and never accept that because a company is known to have particular ways that it makes glass that it might not employ other ways to achieve that goal.
One of the truely great things about glass that attracted me to collect, and then deal, is that it is necessary to use a range of diagnostic possibilities - rather than have a back stamp, as with pretty well all types of china/pottery. It's far more of a challenge and far more interesting as a result :wink:
Happy diagonosing, Nigel
