How To Make Glasses From Bottles.
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. Manufactured bottles are used for different uses such as storage of perfumes, drinks and many other tasks.
Empty bottles can be modified by cutting them to make glass bottles for other uses such as for pen storage drinking glass and as a vase or to make a wine bottle light kit in a number of ways:
Heating them under a flame. This procedure begins by scoring the bottle to create the line that the bottle will break off at using a glass cutter or a glass drill. The bottle is then heated along the line while focus the heat directly along the score line you created and constantly rotate the bottle to get even coverage of the heat from a small candle or a small butane torch. Thirdly, dip the end of the bottle you want to break off in a sink or pot full of water after 5 minutes heating. The bottle will not necessarily break off with the first trial so you might need to repeat the process until it cuts off. 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.
Yarning a bottle cut.
The first step of cutting a glass bottle 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. The string or the cotton yarn is then removed from the bottle gently and placed on a dish where nail polish remover or straight-up acetone is added over the yarn until it soaks completely while the excesses are poured 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. Rotate the bottle slowly after lighting the yarn on fire so that the yarn burns at a consistent speed around the entire bottle. After the yarn burns out, dip the cut off end in a sink or pot full of cold water to cut. Sand the edges with a rough sandpaper to smooth and then with a finer grit sandpaper.
