Hi Sally, i just noticed your reply to my question. I have titanium and niobium in my stockpile too, as i can't wear silver in my ears without getting sensitive to it. Niobium's more expensive than silver, but hey ho. I've never tried welding either of those metal due to the specialist equipment, wire wrapping only. All i knew about pewter was that it's soft and over time starts to sag. I recently bought myself some jewellers brass which i really like the look of. But i've yet to make anything out of it. Brass is one of my favourites.
