sorry Helga - but I think we may have encouraged you to look for uranium in the wrong piece of glass (your jug)..........which as Christine has already indicated, almost certainly doesn't contain any uranium, even though it is green. For some people (especially Christine) it becomes second nature to be able to recognize quite quickly those pieces which will contain the fairy dust, and those that won't (just by looking at the pc screen). This jug doesn't look like it is a candidate for uranium, although you can try the non torch suggestions, but it is a good idea to try these ideas for all green glass - because sooner or later you will strike lucky.
I believe you can buy reasonable quality u.v. torches, on line, for something like Sterling ÂŁ9 - ÂŁ10, which is quite good value since looked after they will last many years.
Do let us know as soon as you strike lucky, and let us know how good Dirk's tv idea is.
