Glad you asked...
To identify bronze you can look a the metal and see that it is made of copper and other element. Bronze gives off a brownish look, like the ones give out at the Olympics.
Then again, this answer might help you...
Real metals will have a shine to them while non-metals have a dull appearance. Bronze does not oxidize, meaning there will be no white, crusty film or what dust anywhere. Bronze is very heavy, and also does not rust.
