How to Cut Glass Bottles?- 4 Easy Way to You

Interesting on figuring out how to cut bottles with foolproof, easy, and quick methods? I will show you my most favorite 4 methods for cutting glass bottles, and something like one is the ideal strategy for all your needs. It’s trending on the Internet how you can turn glass bottles into beautiful decoration pieces without anyone else’s help But first, you need to know how to cut glass bottles precisely.

4 ways to cut glass bottles


Bottle cutting might appear to be a problematic experience however is really simpler than one could suspect. 4 ways to cutt glass bottles are the following:

1. Electric drill

The most common way to make a hole in glass bottles with an Electric drill. Before sharing step-by-step instructions I want you to take safety precautions carefully. Wear safety gloves that can help you avoid cutting yourself while working with glass bottles. Also, try to prefer protective gear around your eyes to keep yourself protected from the glass shards. Choose to work in a very much ventilated place ideally outside like a backyard etc.

Keeping the bottle in place,  try to keep it on a flat surface. Mark with tape on the precise spot where the hole will be. The tape will give your bit some traction and keep it from wandering on the otherwise slippery glass surface.

The key to creating a smooth, clean hole through the glass is by using a low rpm, moderate and consistent pressure, and always start with a small pilot hole. Continue drilling at about 400 rpm, and apply light pressure on the drill (a diamond core drill), so you won’t crack the glass. High-speed drilling causes overheating and glass-powder buildup at the drill site; it can also ruin the bit. Remove the tape when it’s done.

Make sure you practice on old bottles that you would not mind throwing away in case the drilling goes wrong.


2. Specialized Glass Bottle Cutter


Use a glass cutter and hold it on an object you want the height of the bottle to be cut at. The glass cutter is held in place and the bottle is spun around giving it a level score line. The score line on the bottle is then held over a flame while the bottle is rotated. After the bottle has heated up an ice cube is rubbed around the score line. Make sure you take all of the necessary safety precautions so you don’t get injured.

Another method uses a bottle cutter which can be bought or homemade. The bottle cutter holds the bottle in place while it is rotated around a glass cutter giving it an even score line. It can be adjusted depending on where you want the bottle to be cut at. The one I used was homemade. The same way is used to break the bottle apart that was used in the second method.



3. Cutting method of waste newspaper


Cut the waste newspaper into 5-7mm wide strips, soak it with water, and wrap it around the bottle wall for 1-4 circles (in the exact location you want it to break) . Light the alcohol lamp, align the cutting line of the bottle with the flame of the alcohol lamp, and keep turning the bottle. Focus the heat directly along the score line, and constantly rotate the bottle to get even coverage.

After the bottle is hot, put it in cold water  to disconnect it. This causes the bottle to break where the newspaper was. Make sure you take all of the necessary safety precautions so you don’t get injured.


4. Iron rod cutting method


First, fill the glass bottle with edible oil to the cutting line, insert the red iron rod into the oil. Before you attempt to cut the glass be sure that the fluid has settled and that none is clinging to the sides of the container above the planned line of cleavage. Then lower the hot end through the bottleneck a couple of inches into the oil and hold the rod steady for at least half a minute.

and the glass bottle will be broken along the oil surface.

When the neck has dropped off don’t grab–or even touch–the lower part of the container … it’s full of scalding liquid and will burn your hands.



Cutting glass is actually quite fun and I would encourage you to play around with the different methods to see which one suits you. It can be quite intimidating but I found by popping them in the sink in contained the bottle so if any of them broke it was easy to clean up. There are other more convoluted and elaborate methods out there for cutting glass bottles but you really don’t need to be putting anything in the oven, blow torching anything, heating wire, string or putting bottles into freezers, so cast those ideas to one side.

Break lines around the top of the bottle may form due to a number of different reasons. If you have a bottle you can’t use because it has broken in the wrong place, don’t bin it, use this bottle to practice with.

Use the sandpaper that came with your G2 wine bottle Cutter pack, and go round the bottle edges, inside and outside using the sandpaper. Smoothen out all burs left during the cutting process. This will get the edges smoothened out giving the final product a more complete appearance. Always carry out this project in a very easily-cleanable environment, like your sink top, to avoid having several pieces of glasses all over your floor.

Just be extra safe with all these methods and it goes without saying that this is not a kids friendlymethods. Most importantly, just have fun and experiment and see what you can create. I hope you found this post helpful and of value. If you did I would love for you to share it with someone who would enjoy it. You can also share your personal experience method with me.
