How can you tell if something is solid gold all the way through or if it’s plated?

Tue, 29 Jun 2010 15:16:36 +0000

I have a really, really old set of glass wear that is 1 inch rimmed gold. I don’t know if it is solid gold all the way thru or if it is dipped or plated. How can you tell without breaking one? Anyone know?

How much gold is there is the world?

I heard once that the total amount of gold in the world (including that as yet undiscovered) would create a cube about the size of Trafalgar square in London. This sound quite small to me and I have 2 questions…

Is this true?
How do we know for sure?
