How to cut a glass bottle?
The Glass bottles, bottles and other pieces of cylindrical glassware are widely used in the preparation of Crafts and also for some uses professionals. On the internet you will find hundreds of different techniques, most of which they use the principle of temperature differences which we already talked about (see). But, as we said, cutting glass by applying heat directly can be very dangerous and it does not give us the adequate results, since it leaves too irregular edges. The way to cut a glass bottle correctly is the same as cutting a flat piece of glass, you use a glass cutter to mark a fracture line, and then the piece is carefully broken.
But it is impossible to make a straight cut in the body of a bottle using only your hands. For this, there are supports that have the following characteristics:
• A support tip, the size of a cork, which is inserted into the neck of the bottle.
• A support structure semicircular and padded to hold the other end of the bottle
• The tip of a glass cutter normal attached to the frame. On some models, the position of it can be adjusted.
This structure allows us to handle the bottle with care, holding it in such a way that the cut is neat and it is only necessary turn it carefully and with a firm and constant movement to mark the entire circumference.
For separate the pieces there are several methods. The simplest is to apply some dry hits to the tip of the bottle, which breaks along the fracture line, leaving the body intact. Another method is to wet at the same time with cold water bottle tip and with hot water the body Of the same. The jets must be concentrated as much as possible. near what can of the fracture line, one on each side. The temperature difference will eventually cause the glass to crack, but if done carefully, both pieces can be saved and this method leaves no stress lines on the glass.
