How To Cut A Glass Bottle Using Glass Bottle Cutter?

To cut a glass bottle, you need your glass bottle cutter and follow some very simple steps. Read the steps below and follow accordingly to get a nice and clean cut on your glass bottles.

Fix The Baffle

You need to start by installing the fixed baffle that comes with the bottle cutter. And to do this, you need to grab the bottle you aim to cut, place it against the baffle, adjust the baffle so it is nice and tight along the end of the bottle, and then fix it in place.

Adjust The Blades

Next, you need to adjust the cutting blade. Once again, you can grab the bottle, place it against the blade, and ensure that it is perpendicular to the bottle’s body, which will ensure a proper cut.

Start Cutting

Once that is adjusted, take your bottle, start rotating it gently on the cutter against the blades to create a cut. Do note that the bottle will not be cut on the machine right now, but will need a few more steps before it is completely separated.

After this step, you will notice a line around the bottle, where it will eventually be separated from.

Outline With Rubber Rings

You will get rubber rings with your bottle cutter, and if you don’t, you can use thick rubber bands instead. Take these rubber rings, and place them on both sides of the cut you just made.

Alternate With Hot And Cold Water

Get some boiling hot water in a kettle, and pour it on the cut, as you continue to rotate the bottle, so it is reaching the entire cut evenly. Do this for about 20 to 30 seconds.

And then right after, get some cold water and pour this in the same way for about 20-30 seconds. If the bottle has not separated by now, repeat the hot and cold water process until it does.

This must be done one after the other immediately, so have the hot and cold water ready before you do this step.

Smoothen The Edges

Once the bottle has been separated, you now can use sandpaper to smoothen the edges of the bottle. This will make sure you can use it without it being a hazard.

You should do this while the bottle is still wet from the previous step, or you can do the sanding completely underwater for a smoother finish.


You can repeat the process with bottles and jars of other sizes, and all you have to do is change the adjustment of the fixed baffle every time you do it.

Practice The Process

If you have never cut a bottle before, we suggest you start to practice first with a bottle you plan on throwing out, before you move onto a clean piece of bottle you wish to cut for upcycling.

This is because, from the pressure you apply while cutting, to the temperature of the water used, these factors can affect how the final cut comes out. Since this also depends on the bottle and its thickness, these factors will vary for different people.

Trying it out gives you an idea of these factors for yourself, so you can be sure when cutting a bottle that you plan on reusing.
