When you come into contact with antique brass, it can be difficult to tell whether they are solid brass, or simply plated with brass. Here are some simple ways to find out.

Using fridge magnets 

Brass is an alloy of zinc and copper which are neither magnetic. Hold a magnet close to the item, if it attracts, it's not brass.

Scratch test

Use a sharp tool to scratch the object. If you see a shiny gold scratch, it is likely to be solid brass. Be careful not to damage the object.

Weight test

Brass is a dense and heavy metal. You could easily tell it apart from the plated ones for items such as kitchen handles. If the item feels heavy, it is likely to be solid brass, if it is not, the handles are usually made of a cheaper zinc alloy. 

Sound test 

Brass will have a very clear and loud sound. Use a metal spoon and hit the brass to see if you could hear that sound. Combine this test with other tests for a more certain conclusion.
