Carolyn, don't worry - you can't move the thread, it has to be the forum moderator who does that - in this forum that is either Javier or Frank.
Now, a blacklight... I bought mine in a Â£1 shop - one of those places that sells everything for Â£1. It has an invisible ink pen and a small UV torch built in - intended for kids to write secret messages with that only someone with a UV light can read, but it's very handy as it slips into a bag or pocket and shows up UV glass when shone on it. It also doubles up as a security marker pen - mark your glass with the pen end and see it with the UV end... neat! I think stationers also sell the security pens, and I know that UV torches and bulbs/striplights are available from Maplins
- search for blacklight.
Murano and uranium glass... yes, it was (possibly still is, I don't know) used on Murano, but from what I have seen - and I'm by no means well-up on this at all - it was used in conjunction with non-UV glass e.g. as a casing over a coloured layer as in Chuggy's ewer
which prompted your original question. I've never seen anything from Murano which is made wholly
from uranium glass but that's not to say it wasn't made... as I said I'm not an expert on Murano by a *long* way!
Uranium glass was made in the UK and in Europe (no idea if it still is), and is still made in the USA by glassblowers such as Jack Loranger
. The UK and European production I have seen has been pressed glass like that on the 1st.Glassman
site - I really do not know if it was used for other types of glass production.
I hope we can get this thread moved over to Glass soon as there are users who are more clued up on uranium glass than I am who will be able to add more for you, I'm sure.
