Indeed, we use it at work on Jags for minor scratches on screens on rare occasions.
It's called 'Jewelers Rouge Powder' that is supplied to us from Pilkington glass makers. I don't know where you would get some, maybe a net search It's a powder that you mix with water to make a super fine paste.
Verry good stuff, but caution must be used not to polish through the toughened layer of glass.
