Never ever attempt to cut or polish hardened glass, and never use
anything else for furniture use.

Well, I don't actually know if it's hardened or not - only that it's
laminated. Maybe there's some sort of identification mark on it somewhere
- I'll have a look later...

You finish the glass first, *then* toughen it by heat treating it.

Any glazier will do this, or get it done.

That's useful to know...
