I've heard about scoring the glass on only one side and scoring it on
both sides as the preferred way to cut/break glass. I've done it both
ways. Anyone got any real insight into this matter????

score it on one side. break apart by pulling down on each side of the cut
with the cut on the top surface, or break on a sharp edged tabletop if the
piece of glass is large and the part you're cutting off is not small.

Any comments on scoring 1 side vs both sides before breaking??


I've never heard of scoring on both sides, only one side. Could
two-sides be for extremely
thick glass?

I should add that this particular piece of glass I am going to cut is
double thickness from an old storm door. I know that the glass is NOT
tempered.

i cut up to 1.5" glass usually. the score breaks the surface tension. you
bend away from the score, causing a compression of the bottom surface. if
you scored it, it would make no difference, and would probably cause your
cut to wander since they won't line up exactly anyway.

how do you know it's not tempered? lack of a label doesn't guarantee that.
if it's a door, there's better than an even chance that it is tempered. i'd
wear eye protection before scoring it, if i were you.

Clean the glass. Clean it a second time. Drizzle a line of kerosene
on the line. Score. The scoring should sound like a continuous
ripping. Put the score on the edge of a table and give it a quick
snap. You could tap the glass along the score line if the glass is
thick. I have not ever tried scoring both sides--don't need to.
Always, protect your eyes.


That's the way I did it as a kid working in the old time hardware store.
The glass cutters sat in a tin can with kero.

How to Cut Glass

Clean off a portion of a table or workbench and make sure it's flat,
then lay a damp rag over the area. The rag will cushion the glass,
and the moisture will keep it from slipping.

Rest a piece of glass flat on the rag so that it is completely
supported. Then clean the glass with any household glass cleaner.

Measure and mark the glass for your first cut line.

Line up a metal straightedge with your marked line, then shift it
slightly as needed to account for the offset of the glass cutter's
wheel.

If your glass cutter is not the self-oiling type, lubricate the
cutting wheel with a drop of lightweight machine oil.

Now you're ready to score the glass. This creates a weakened area
much like a fault line. You'll be able to snap the glass easily and
cleanly along this line.

Secure the straightedge with duct tape. Hold the glass firmly in
place, then draw the glass cutter along the straightedge with a firm,
smooth stroke that goes from edge to edge. If you do this correctly
you'll hear a subtle but steady scratching sound. You have one chance
to do this right because glass should not be rescored.

Remove the straightedge, flip the glass over, and tap gently on the
back side of the score line with the ball at the end of the glass
cutter. This extends the weakened area through the thickness of the
glass.

Now hang the glass over the edge of your table and tap it lightly to
break it along the scored line.

Make your next cut in the same fashion. Then clean the glass again to
remove any traces of cutting oil.



Google cut & paste. Nice job :-)

Old glass can be a lot harder to cut.

BTW, that building I talked about a few months ago that was being torn
down had 4 mirrors 6 or 8 foot wide by 10 foot high each. To buy new
would be 500 dollars a piece, 2000 total, I was told. Despite that,
we offerred them free to a glass guy and he didn't want them. Too
hard to use them without breaking them, or too hard to cut them for
the next location without breaking them. They are 40 years old.

So we left them, and I suppose the new owner who is tearing the
building down will too.

BTW, the movie scene where the cat burglar scores a circle on the
outside of the glass and then taps it and the circle breaks out and
then he can stick his hand in. NOT TRUE. I'm told that you can't cut
glass from only one side. You have to tap on the side opposite the
scoring, or have a fulcrum on the other side to press against.
