what about other objects from krypton that are not organic, ie, metal, cloth, glass, etc. are they indestructable as well?
I remember reading an older superboy comic where he and martha took some glass from his crashed ship, and made lenses for his glasses so he could use his x-ray vision while wearing them without melting them.

I was just wondering if the same thing still applied today in modern comics.
