Transparent… palladium?

Which is like transparent aluminum, except that it actually exists outside of Star Trek IV: The Voyage Home.  I’m guessing: there’s science involved, and I let my wife handle the science above a certain (read: ‘minimal’) level.  Sounds like they’ve worked out how to make the glass significantly less brittle, which will give all sorts of structural advantages.  Was that a safe summary?  I think that was a safe summary: I’m going to quit while I’m ahead.
