It might be magic, it takes something ordinary and turns it into something extraordinary like he did with those bullets he shot at Laxus, he fused copper and zinc together that turned them into what he made them to be and same for those missiles he shot a few chapters ago but not really sure what he fused together to create them but anyways, its pretty much a chemistry based magic.
