....oh no
What Maple had was not exactly the 'melty chemical'. It was something Silver made, and from what I understood, akin to the original chemical, but not quite. What Silver made was a catalyst originally created to destroy the Inhuman qualities of someone, but not kill them. When she realized/learned that it would kill most, if not all, Inhumans, she destroyed it's power by using the crystals, and it instead targeted metal. I'm not quite sure what exactly the original chemical was, or what it did, but this is just what I know of what happened with Silver's catalyst.
