The things you need to gather before cutting:

  • Glass cutter
  • A tape
  • Goggles
  • Hot water
  • Cold tap water
  • A pair of gloves

Steps of Cutting a Bottle Using a Glass Cutter

Specify a cutting line

Using masking tape, you can specify a line. It will help you cut the bottle according to the marked line.

Place the tape where you want to cut the bottle. Make sure the tape is well-adjusted and straight. This will avoid any incident that creates a snag.

Again, you can leave the label where it was. The label can also work as a marking line. You can remove it later after you cut the bottle into two pieces.

Start scoring

Hold your cutter and place your arm somewhere comfortable. Your hand should be angled from a steady place. If your arm moves, the cut will not be precise. It will be jagged.

You can raise your arm, which will make your job more comfortable. To do this, place a piece of cloth under your arm and fold it up.

Place the cutter along the line of the masking tape. Start marking it around the whole shape. This will help you cut the bottle precisely and make your task easy.

While scoring with a cutter, make a continuous line. The intervals of lines can make it look jagged. Though it is a matter of practice, you can still try to make it perfect.

Hold it inside the hot and cold water.

Run the scoring-lined bottle inside hot water. Wear gloves and rotate them in the warm water.

Then, take the bottle and run it under cold tap water. Repeat the steps again and again. You will hear the bottle scratching. In this way, the bottle will be divided.

Safety measures

If you use a rotating cutter, take some safety precautions. You must wear goggles or a face shield to protect your eyes and face, and you must wear a long-sleeved shirt to protect your hands.

Don’t forget to wear gloves. Wear gloves when you put your hand into the warm water.

Other Methods

You can tie a rope around the bottle where you want to cut it. Then soak it in a flammable liquid. Once it is washed, set it on fire. Then, the flame will be extinguished by immersing it in cold water. You will get two portions of the bottle in your hands.

You can use adjustable roller cutters to cut the bottle into two sections. The bottle is placed against the blade and rotated in a counter-clockwise direction. This will score the bottle. Then you can use the hot and cold water to break it.

However, these methods don’t work properly and can’t be used for long. So, using the hand cutter to score and break the bottle is convenient.

How to Polish the Edges of the Cut Bottle?

How to Polish the Edges of the Cut Bottle?

To make your bottle more appealing, you have to smooth the edges. Without smoothing, you cannot even craft or work on it. There are many ways you can start polishing. It depends on you how perfect you want your bottle to be.

The smoothing methods are given below in detail.

Using a diamond file

You can use a large 600-grit diamond file to polish the surface. There are many shapes of these files. You can use any of them.

This one file can work on both sides, as it is big enough. These are very effective in small bottles. After this, you will get a suitable surface finish.

You can use the black silicone polisher if you want it to be smoother. Before polishing the edge, you can remove the bumps by using a cylinder burr.

These are abrasive tools. You should use them carefully. Otherwise, the bottle might slip and crack.

Using a sandpaper

Eighty-grit sandpaper can smooth the edge. If you can’t easily get the sandpaper, you can use emery paper. Wet the paper before rubbing the surface.

Hold the paper with one hand, and with the other hold the paper. Hold down the edge of the paper and scrub on it in 2 to 3 circles. Continue to do this for at least 5 minutes to get a better finish.

Use higher grit papers for a better finish. Remember to smooth the inner surface as well. Once you are done, clean the whole bottle with a piece of cloth.

If you find using your hands difficult, you can switch to another method.

Using silicon carbide

Place a float glass or any piece of scrap glass on a surface. Add water to the center of the glass, and then put silicon carbide on it. Stir the powder gently using your fingers. Wear gloves while doing this activity.

Press the rough edge of the bottle on the silicon carbide solution. Spin the edge there for 30 to 60 seconds.

Use an emery paper to smooth the surface inside. Then wipe off the bottle with a clean cloth.

How Can You Use the Bottle?

Once you are done preparing the bottle, you can start making it look good. Recycled bottles can be turned into valuable items as below:

  • Pen holder
  • Flower vase
  • Toothpick holder
