I show 3 methods to cut glass bottles. One with a string, one with a glass cutter, and one with a homemade bottle cutter. After a few tries cutting the bottles it becomes pretty easy to do. You can make drinking glasses, lamps, vases, and many other things from the cut bottles.
Step 1: Method #1
The first method is with a string that is wrapped around the bottle then is soaked in a flammable liquid. The string is lit on fire while the bottle is being rotated, when the flame dies down the bottle is put into cold water. This causes the bottle to break where the rope was. Make sure you take all of the necessary safety precautions so you don’t get injured.
Step 2: Method #2
The second method is to 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. After a while the bottle breaks apart.
Step 3: Method #3
The third 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.
