dafeeeeeeeeeesh (if you changed the scraps, say, from steel to carbon, then they'd change [in the general aspect, if you go really deep then technically the change is only to the quantity of fundamental particles], but if you just use tonal manipulation to turn the scrap into a ship hull with the same composition then they'd stay the same, it's just that their arrangement would change, in the end the only change that tonal manipulation actually makes is to the fundamental particles/fields of the material)
(OORP: of course, I'm no quantum physicist, it's just based on that XD)
