How to Cut, Score and Break Glass

Glass can be cut into strips, geometric shapes, circles, ovals, curves and with a glass saw, almost any shape.

Some Things to Keep in Mind

• Warm glass (glass at room temperature) cuts easier than cold glass

• Work surface needs to be flat

• Score on the smooth side of glass rather than on the textured side

• Hold glass cutter in a vertical position as you would a pen or pencil

• Don’t use excessive pressure. Too deep of a score can result in a bad break

• For protection, it’s a good idea to wear glasses or another type of eye protection

Straight Cuts

When making a straight score, start scoring the glass from the point farthest from your body and pull the glass cutter towards you. Once a score line is made, use running pliers (if strip is at least 1” wide) by placing the running pliers centered on the score line and gently squeeze the handles. You will hear a slight cracking noise and see the glass separate along the score line. Or, hold the stained glass sheet over an edge of a table with the score line slightly overhanging the edge. Use breaking or grozier pliers and apply gentle pressure in a downward motion along the score line. This can also be done with your hands using the same downward motion. Practice will make for perfection, soon.

Curve Cuts

To make a curved cut, use the glass cutter to cut off sections one at a time. This allows you to work into the curve. Glass likes straight lines or lines with gentle bends. If the shape has irregularities or small projections, these are easily removed with a nipper or glass grinder. In other words, don’t rush the cut especially if it is an inside curve. Just chip away at it a little bit at a time.

Cutting Circles

Score the glass in the shape and size of the desired circle. Use a permanent marker to place a dot where you start scoring to avoid going over the starting point. Next, place the scored line side of the glass down on a piece of corrugated cardboard. Use light pressure and press along the score line until you see it run the circle. Then, turn the glass over to the side you first scored on and score several tangent cuts radiating out from the circle. Finally, break each tangent score line with breaking pliers. The circle should cut clean without any jagged edges.

How To Avoid Common Problems

• Cutter wheel wears out quickly – Lift your cutter up instead of sliding it off the edge of the glass or cut on a surface covered with vinyl or carpet

• Bad breaks after scoring – Too much pressure was applied on the glass cutter

• Score line looks like dotted line – Cutter wheel is dull and needs to be replaced

Be sure to turn your pattern template over when you are tracing your pattern onto the backside of the glass where it smoother. Failure to do this will end up in wasted glass and lots of wasted time, not to mention frustration.

About the Author

I started out as a stained glass admirer. After a class in stained glass, I became addicted. At first I made stained glass to decorate my home, which lead to friends asking me to make stained glass for them. Now I am a full time professional making stained glass as well as instructing others on how to make stained glass. My studio is located outside of Chicago, Illinois.

Cutting? Self-mutilation? This is a genuine question - I don't understand.?

"Cutting" seems to be rather common these days. But when did it begin and how? And why "cutting"? Hear me out, please: I know some people also burn themselves with cigarettes, candles, whatever. Why not "crushing" - in which one crushes finger tips, toes, whatever with pliers? Or "breaking" - in which one breaks their own fingers, toes, whatever. Or "pulling" - in which one pulls out their own hair?
What is the psychology behind one's chosen mutilation vs. some unchosen form or mutilation.
I'm just curious as to why one form of mutilation and not another.
Tasha B - Thanx, I figured it had more to do with attention-getting, but the "control factor" is very important also, I suspect. (I work with abused dogs, and when under stress, dogs chew things - it helps to release tension just as cutting must do for some people.)

Well two things, self mutilation, especially cutting is generally used more as a way of getting attention then an actual abuse of the body. Scars are noticeable, they can be hidden but finding the evidence of cutting is much easier then finding the evidence of "bashing" or "pulling" in most cases. Many cutters hope that someone will notice their self-abuse and seek them out.

Cutting is also used as a measure of control. Those who cut tend to not feel as if they are in control of the situation their life is in. So cutting is a way of releasing tension and sorrow in a way that they can directly control.
