Dave,
I have no experience with such matters, but I would go the "mechanical"
route by using an fine abrasive stick instead of a torch.
I may be completely off base, but if there's a chance for some kind of
damage due to thermal stress caused by heating the LDG (like shattering or
cracking,) I wouldn't want to risk it. Others may have done similarly
without problem, but then there is the famous Mr. Murphy and his Law...
That's my 0.02, for what it is worth. Good luck, whatever you decide to do.
Ed

Hi
One of my lumps of LDG has a very small (<3mm) chip in it - ordinarily it
wouldn't bother me at all, but it's left a teeny sharp pointy bit sticking
out that always catches one's hand.
What would be a appropriate way to remove this point? My initial thought
was
to carefully play a blowtorch across the asperity to melt it down and
reduce
the sharpness, but would i end up with an exploded, thermally shocked
handful of glass chips?
Abrasives could also be used, but I'd feel more comfortable with a
blowtorch
and being careful( used to make glass labware when I was a kid - not too
successfully, but without serious accidents!)
Or should I just leave well alone?!
Anyone out there with experience with LDG?
Ta!
