Brass has zinc added to make it bronze.
It was my understanding bronze is copper and tin.

Brass is copper and zinc.

One of the reasons that lead is used for casting bullets is that it is liquid at just above the temperature at which it "freezes".
This is confusing. When a solid melts, it's not 'frozen', but liquid. Is there another state between 'frozen' and 'liquid' that brass goes through?
