Hi everyone, Many thanks for the help on silver and pearls; I have a
further query which follows on from the earlier titanium thread: I
bought some stuff which looks much like a jeweller’s discards at a
school fete; mostly discs with one ring made of bent tubing, in
bright colours which look closer to anodised titanium than aluminium.
Decoration has been added by rivetting, in a way that I would expect
in this range of metals. They’ve been drilled in the wrong places,
scratched and so on, and I bought them because it was a good cause
and they are useful for practising on. But it would be good to know
just what metal I will be practising on. Can anyone tell me how to
distinguish these metals?
