Thanks Guardian for the simple answer. And for those posting spam it does nothing for this site. I never read them so why bother?
Platinum, however, is an extremely rare metal, even harder to find than gold. It doesn’t share the exact properties of gold – for example, you won’t find much “platinum leaf” around – but it does have a very high resistance to heat and its melting point is extremely high.
I do not really know that much about platinum but I can see your point about it being pure. IF it is pure then I too think that it would have a better quality.
