Anneal - cut - retemper

I got an e-mail asking where one might get some tempered
glass cut. The pieces in question are 3 meters by 2 meters
by 1 and 1.2 cm thick.

I suggested that it may well be cheaper to simply have
the new pieces manufactured from scratch, but the querant
wishes to shop around... so the question is, Does anyone
know of a place that could anneal some glass that size,
cut it, and retemper it?

TIA

Those are pretty big sheets of glass, which means
that it will likely shorten the list of folks that
can do it quite a bit - probably to one of the big
manufacturers...which will make it pretty pricy as
they don't really do that sort of thing.
I would recommend first off that they redesign
the project to use the glass as is. If that is not possible,
I think your recommendation, of simply buying new panes
is best. I can't say that I have really ever heard
of folks re-tempering glass of any size. I fear that
the process just won't work that well.
Perhaps he can sell them on Ebay as solar
collector panel covers, and, make back some
of the cost.

Having formerly worked in a glass tempering plant, the short answer is can't
be done cheaply and most companies with an oven won't even attempt it. Toss
out the old and order up the new.....

It would be cheaper to have tempered glass ordered to spec rather than ship
it back and forth. Also, none of the annealing places I know of will
guarantee YOUR glass that you send them will make it through the oven. But
if you order glass with holes or notches or whatever, they will make it and
ship it to you. If some break in the oven while they are making it, it's
their problem not yours.
