    * The first question:
    I think it depends on the metal. For example, if the metal is Aluminum, when it rusts, it will become stronger. If the metal is Iron, when it rusts, it will wear away. ect.
    ==> All of them are correct, in some ways!

    * The second one:
    I think "a" is the best choice. You know, Iron or metal in general, is easy to receive heat but it's also easy to lose its heat, so that it's not suitable to make cooking pot, though we usually use it!
    Once you use glass, especially a special kind of glass, it can keep the heat longer!
