How to Cut Glass Bottles?

Many people throw away glass bottles directly after they have used them. In fact, glass bottles have multiple uses and can be reused. If we want to transform the glass bottle into a vase or pen holder, we need to cut the glass bottle. In order for everyone to cut glass bottles smoothly and get a smooth cutting surface, we have summarized the following methods for reference.

Find a line to cut your bottle. As for the line to cut, you can find a glass cutter or glass drill. If possible, you can find a bracket to fix the bottle so that you can draw the line more neatly.

To heat your glass bottle along the scribed area, you can use an electric welding or butane nozzle heat it. Aim the flame at the line drawn on the glass bottle and keep rotating the bottle so that the flame heats on each side of the bottle.

After you bake the bottle with a fire for five minutes, quickly put it in cold water to cool down. It can be done in a sink or pot with cold water.

You may need to repeat the heating and cooling process several times to break the bottle.

Use sandpaper to polish the broken glass bottle. When you want to sand sharp places, you can use very fine sandpaper.

 

You need to find a clear line as the target where you want to cut and use a glass cutter or glass drill to draw a line. Don't draw too many lines, it may make your bottle become irregular after cutting.

You need to let the bottle expand in hot water and shrink in cold water to break the bottle. You need to keep the glass bottle soaked in cold water and hot water alternately until the bottle breaks.

After repeating it several times, the bottle may break neatly along the drawn line.

Sand the bottle with sandpaper, and when the edges are basically neat, sand with fine sandpaper.

At the place, you want to cut, wrap the string around the bottle three to five times. Tie the rope together and remove the excess part.

Slide the thread off the bottom of the glass bottle and put it on a small plate. Pour in acetone until the thread is completely wetted (note that acetone is irritating and flammable, it needs to be used with care, wear protective equipment, and be careful to stay away from the fire). After soaking the rope, take back the excess acetone and put it away.

Tie the rope where you want to cut, make sure the rope is tightly wound together, or your bottle will not be neat even if it cracks.

You can ignite the rope with a match or a lighter. Rotate the rope slowly to make the rope burn.

After the rope burns, immerse the glass bottle directly in cold water. The bottle should break neatly along the place where the thread is entangled.

Use coarse sandpaper to smooth out the jagged edges of the bottle. When you want to sand sharp corners, you can use fine sandpaper to finish.

You will cut your glass bottle along this place. Two pieces of tape can be used to mark the location, but not too tight or too wide. It is best to form a line where you want to cut.
