Wanna make a cut on glass?

It's not a secrect to cut glass in any shape your required.

Follow up our step and make youself professional.

Let's rock and roll ;)

Request a place as a safe work area

1). It’s required a large flat, preferably slightly soft surface that won't scratch your glass. Working area asks for being easy to clean.

2). Carpet is not suggested since there is risk of having glass shards if something breaks.

3). Make sure no pets and children staying in your workspace or nearby materials.

Require a glass cutter and some light oil

Glass cutters are about the size of a pencil with a diamond or a hardened wheel that marks a line of score into glass along with which glass is broken cleanly.

Cutting oil is able to buy at a stained glass store, or use a small amount of kerosene.


1. Measurement and score for straight line

From one edge of the glass to the other edge, with straight line ruler or something with a straight edge, the score must run fully.

There is a high failure rate when breaking if score line is longer than 609.6 mm.

Leave about 152.4mm of glass on each side to grip and break.

Cutting small pieces of glass needs to use special tools, like pliers or a light hammer, to break off glass you are not able get a hold of.

Fill oil into the cutter body tank, grasp it like a pencil, and Lay out a straight edge. An oiled cutter creates a smoother score line. Make sure the cutter is closely touching with ruler edge or straight edge

Apply pressure to the glass, pull the cutter along the ruler, run the cutter smoothly from one edge to the other.

It’s pushing too hard (a very common mistake) or working without oil that the cut gets snaps and pops, having gritty sound.

It means good cut that continual smooth sound likes ripping silk.

The less sound you make, the better your score will be.

Pressing too hard in one spot and perfectly in another, the glass will not break the straight line as scheduled. Microscopic imperfections in the score will cause the cut to go askew.

Never run back and forth over the line if missing a spot.

Check score. Wiping the oil away, a score should be not popping and is barely visible and looks like a small scratch, nothing more.

After cutting, breaking and smoothing is required (Suggested 3-8 mm glass).

Hold the glass as grasping each side of the cut carefully.

It’s something like you were trying to break a potato chip in half with two hands.

Twist the wrist to have a minor pressure to break the glass along your score. Don’t move the elbows. Only your wrists simply twist (your right wrist will turn clockwise and your left will turn counterclockwise). You're done as soon as you have two pieces of glass instead of the one you started with.

Your pressure will make a visible crack runs along with the score.

Make it continued.

Remove the sharp edge by fine sandpaper or a sharpening stone. This edge is a cross that the vertical edge meets the horizontal surfaces.


2. Cutting on a Curve

Follow a pattern that connects to the edge. If you are cutting a freehand shape, make sure you are breaking along lines that run from edge to edge. Mark your lines with a marker or set your glass over your pattern.

Use several straight lines to cut a sharp curve. You should be able to score along gentle curves normally with a steady hand. For tighter curves, make a series of marks that run along part of the curve and skew off at a tangent outside the piece you want.

Flip the glass over and gently press on the center of your score from the backside. You will start a run this way. Follow the run with light pressure and you can watch the glass separate where you scored it. If your score is too close to the edge of a piece of glass, it may run to the edge instead of along your score because that is the easiest path for the run to take.

Make some relief cuts to remove small pieces at a time instead of all at once. The smaller the relief cuts, the more accurate your cut will be. Grip smaller pieces with pliers and snap them off.

Smooth your curved edges using a glass router. This machine uses a spinning wheel with fine diamond chips as a grinder. Turn on the router and press your curve firmly against the grinder to smooth out your curve. Then sand as normal.
