You will need to heat the entire bottle and not just the top. Try it
and you end up with a broken bottle.


Really? *I have mended glass ware by just heating the area that was chipped.
Slow heat with slow change in a warm room seems to work for me.


Like I said...try it. Heating up the top of cut bottle is completely
different than mending a little chip. I surprised the glass didn't
break. some folks who have had success in fire polishing the top of a
cut bottle put the bottle in a kiln, heat the whole thing up and then
use a torch to fire polish the cut edge. Even that is tricky and you
have to know what your doing. A tad too hot in the kiln and the bottle
will start to slump. The whole bottle needs to expand and contract at
the same rate or you'll have thermal shock. You certainly won't be
able to heat the entire bottle with a torch and expect it not to break
at some point...unless you have it in a kiln.
