Re: Polishing scratches out of glass |

My Father In Law is a glass engraver, and is often asked if it is
possible to remove scratches, or change/erase the engraving on glass.
The usual answer is that while not 100% effective, you can significantly
diminish most scratches with a rubber wheel on the end of a dremmel type
tool.

You mean with rouge on it?

I asked my FIL http://www.bertcollis.co.uk/engrave.htm about hard
glass (i.e. normal window glass) in particular, and this is the response:-
"Removing scratches from plain glass is a) difficult, B) tedious, c)
time consuming. To do it properly (ie successfully) one needs a set of
felt cones impregnated with diminishing sizes of polishing grits in
paste form.
Endless patience is essential. ( I have a small kit of polishes and felt
tips but not the patience!) Personally I only polish out engraving or
scratches if I am going to re engrave the affected area since one is of
course altering the surface level and thus the angles of reflection.
There is a man in Purleigh who specialises in repairing scratched or
broken glassware and he has a whole armoury of powered discs and belts."
So there you have it!

Looks like the "bobbins" in
http://www.screwfix.com/app/sfd/cat/pro.jsp?ts=21851&id=30347
are just rubber wheels.
I wonder whether the white powder is cerium oxide. I'm planning to order a
kit once I've got enough other stuff on my shopping list to get the order up
to £45 for free delivery ;-) I'll report back on progress.

OK, well I've got the screwfix kit. The bobbins are made of felt, and as far
as I can tell the powder is cerium oxide. I've just spent about 30 minutes
polishing some scratches out of my windows, and it does work, although
progress is slow. The scratches I'm removing from the glass have been caused
by someone sanding the frames, and they're not particularly deep, just
annoying. Even though they aren't deep they still take quite a while to
polish out, so I wouldn't fancy doing this if the scratches were much worse.
It seems a bit mean only providing two bobbins, I'm not sure they're going
to last the course, and I don't want to shell out another £20 for two felt
bobbins! Lots, more windows to polish yet, maybe I should have just reglazed
the damn things :( Probably any sane person would live with scratches, I
think I'm becoming obsessive.
