It waters out the use of categories, as it adds loads of stuff into the Smelted category, so that when someone actually wants to find something Smelted  it is hidden in all the random stuff that can possibly be smelted.

I do see why someone would want Category:Smelted, but it should have a clearer definition or more narrow description making it more useful. (That is by the way, a faith a lot of categories suffer from, a broad and almost useless descriptions)
