Thanks for that UPS,
That was exactly what I was looking for :)
To shed a little more light on what you say about the Romans I can
recall from my Latin lessons of many years ago that the whole of the
water irrigation and domestic supply in Rome was using lead piping.
The latin for lead, Plumbum, is the origin of its chemical periodic
table symbol of Pb, and also gives us the modern English word Plumber.
Thanks again for your help.
Silver solder it is then ;)
