Making Glasses From Bottles.
The neck and the mouth of a bottle is usually slender than the other part of the body. A gob is made by cutting of a stream of molten glass from sheet glass or from glass container glass with a clipping blade to form glass cylinders using either the blow and blow process or the press and blow technique. Manufactured bottles are used for different uses such as storage of perfumes, drinks and many other tasks.
There are different procedures on how one can make glasses out of a wine bottle which includes:
Using a flame. First, create a line where you need the glass to break of using glass bottle cutter tool like a glass cutter or a glass drill by scoring. 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. 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. The bottle cuts off with rough edges hence one should rub the edges with a square sand paper and then with a finer grit sandpaper as soon as they are finishing the cutting to avoid cutting themselves until it is ready for use.
Use of a yarn to cut a bottle.
First, wrap 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. 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. Smoothen the edges with a rough sandpaper and then with a finer grit sandpaper.
