How can you tell if something is copper or copper plated?

To determine whether an item is made from solid copper or simply plated with copper, take a file to an out-of-sight portion of the object. If filing reveals a different shade of metal, the object is likely copper-plated. Solid objects will be the same color all the way through.

What household items are made of copper?
