The neck and the mouth of a bottle is usually slender than the other part of the body. Historically, glass bottle production can be of sheet glass or from glass container glass and can be manufactured by the process of blow and blow process or the press and blow technique which involve the cutting of a stream of molten glass with a clipping blade to form glass cylinders known as gob. When the manufacture of the bottles is completed, they are distributed among different uses like storage of perfumes and drinks.
Bottles that were initially used to store drinks can be modified by cutting glass bottle to form a glass that can be used to store pens, drink or as a vase in several ways some of them being:
Using a flame. First, create a line where you need the glass to break of using glass bottle cutter tool tool like a glass cutter or a glass drill by scoring. Secondly, heat the glass along the line you created in a direct flame from a small candle or a small butane torch while constantly rotating it to ensure even distribution of heat. After 5 minutes of heating, one can dip the end of the bottle they want to cut off in a sink or a pot full of water or ice. If the bottle does not break, repeat the process of heating and cooling until it breaks off as desired. Finally, rub the edges of the glass immediately after it breaks, to avoid cutting yourself. With a square sand paper and then with a finer grit sandpaper.
Use of a yarn to cut a bottle.
The first step of candle maker kit using a yarn or a cotton string involves wrapping the yarn or cotton string around the bottle 3 to 5 times at the area where you would like the bottle to break, tie the ends together and cut the excesses. Slide the yarn or cotton string off the bottle, put it on a dish, pour nail polish remover or straight-up acetone over the yarn until it is completely soaked and then the excesses into the bottle. Secondly, remove the yarn or cotton string from the bottle gently, place it on a dish and pour nail polish remover or straight-up acetone over the yarn until it is completely soaked and the excesses into the bottle.
The third step should involve returning the yarn on the location where the cut off is supposed to happen and ensuring that the yarn loops are close together and tight enough to allow a level and clean cut off. Use a match or a lighter to light the yarn and rotate it gently to allow for consistent burning. Put the bottle end you want in a sink or a pot filled with cold water after the yarn is burnt out. Sand the edges with a rough sandpaper to smooth and then with a finer grit sandpaper.
