Cutting the bottle is a good way to recycle the glass bottle and a good reason to have a drink :) There are several cutting methods for glass bottles without bottle cutters. In this Instructure, we\'ll look at the way to cut the glass bottle in half using a spray light. This method is also called glass cracking. What is needed: you can use a metal saw if you do not have a glass cutter. Break the saw in half and line the bottle with a sharp angle. If you are interested in this video version of Instructure and the embedded video will not appear on your mobile device for your own security, here is an alternative link to wear gloves and goggles. Make sure to remove any cork from the bottle you are going to cut. Draw a short line on the bottle. You will want to do it as directly as possible. It is a good idea to use the practice bottle. Place the bottle in the center of the turntable and keep the torch at the same height as the line. Rotate the turntable and heat the bottle until the line expands and divides the bottle into two halves. You can grind the bottle into a wine glass or something with sand. I like to grind the bottle into sand with King Kong sand powder. Fast and effective.
