Decor made from glass bottles, quite popular in lately, and since many are interested in the question of how to trim glass bottle at home, without using a glass cutter, then I want to devote today’s master class to a simple, but in an interesting way cutting bottles with thread...
In this connection, the topic of this master class is “How to cut a bottle with a thread - nothing complicated!”
For work we will need:
1. Glass bottle;
2. Wool threads;
3. Solvent (you can use kerosene, alcohol, cologne, acetone);
4. Scissors or stationery knife;
5. Gloves (will protect the skin of your hands from exposure to the solvent);
6. Lighter or matches;
7. To protect your eyes, just in case, glasses (in fact, there are no fragments, but there is no need to be too careful);
8. Deep basin filled cold water.
So, how to trim a bottle with thread? Let's take it wool thread, measure and cut it so that it is enough for 3-4 turns of the bottle.
We immerse the measured and cut thread in the solvent, and immediately wrap the bottle in the place where we plan to make the “cut”. The thread can be simply wrapped or tied in a knot; in this master class I simply did the wrapping. 
After that, we set this thread on fire with matches or a lighter, and it is better to hold the bottle in an inclined position - strictly horizontally (parallel to the ground), carefully twisting it around its axis. 
The fire will burn for about 30-40 seconds, as soon as the lit thread goes out, quickly lower the bottle into a prepared basin filled with cold water. 
Next, the characteristic sound of cracked glass will be heard, and the bottle will instantly split into two parts. This type of glass cutting is based on a rapid change in temperature; we all know from physics lessons that when heated, the glass expands, and when cooled, it contracts, respectively, with a sharp change in temperature, a kind of destruction of the glass occurs and it simply cracks! 
We figured out how to cut a bottle with thread, but how to process sharp glass edges? You can use sandpaper or a stone to sharpen knives. Lastly, you should process the edges of the bottle, previously immersed in water, so processing is easier and faster (it is better to protect your hands with rubber gloves). Friends, I ask you not to forget about the notorious safety precautions, no matter how you work with fire and glass, safety glasses for your eyes, gloves for your hands and a basin with a large number water is a must!

Many people know that old bottles can always be used, after “recycling” them a little, for useful things for the home. But not many people know how easy it is, because they don’t imagine how you can cut off part of a glass bottle without a special machine, and even in a matter of minutes. At the same time, by cutting off the neck of a beer bottle, you will get 2 excellent and original beer glasses: the lower part will be used as a man’s, the upper part as a woman’s; By removing the top of a wine bottle or champagne bottle, you can later use the bottom as a flower vase, and the top again as a stemmed glass. In the same way, the lower part of a fairly spacious bottle can be converted into a lamp. Well, as the process description below demonstrates, cutting glass is surprisingly easy, and you can always apply this process to any glass object. It is also safe and practical way cut glass.
Surely, this is also a fun and amazing trick to show off in a group or at a party. Shocked faces will be your reward, as most have never seen anything like this before.
You will need:
- lighter fluid, or nail polish remover, or, for example, kerosene;
- a long and relatively strong piece of thread;
- a bowl/basin with cold water, large enough to accommodate the entire length and height of the bottle;
- safety glasses;
- lighter/matches or something similar of your choice;
- spoon (if necessary);
- diamond-coated file or fine-grained file sandpaper- for finishing the edges of cut glass.
1. Soak the thread for several minutes in lighter fluid or nail polish remover (or kerosene). The length of the thread can always be pre-measured using the bottle.
2. Mark a straight cutting line on the bottle with a felt-tip pen if you are cutting the bottle not just for fun, but for a vase or other decorative purpose. Otherwise, skip this step.
Tie the soaked thread a few (2-3) turns around the bottle along the line where you want to cut the glass. Naturally, you need to wrap and tie tightly! But do not make a large knot so that the cut part ends up even and an oval does not form under the knot after burning the thread. And a few turns of the thread should not create a thick stripe.
3. Wear safety glasses. Holding the bottle over a flame-proof surface, light the thread. To prevent the thread on one side from finishing burning when it starts to burn on the other, you can carefully and quickly light it on several sides at once, but under no circumstances hold the lighter/match by itself for a long time near any part of the bottle. Let the thread burn out completely - keep the bottle at a safe distance until the thread burns out completely on its own (the fire will also “go away” on its own).
4. Then immediately put the bottle into cold water in a bowl/basin - dip completely and hold the bottle with your hands. A sharp change in temperature will lead to the glass cracking exactly along the burning line of the filament: this is why the layer of filament on the bottle should not be wide!
5. Gently pat the glass top part spoons - along the line where the burning thread wrapped around the bottle was located, if the glass did not break on its own. It is better to keep the spoon at hand immediately so as not to miss the moment.
6. Smooth any ridges on the edges of your desired bottle cut pieces using a diamond file/fine sandpaper. For this part of the process, make sure the glass is wet and sufficiently slippery, otherwise you will have problems when working with the diamond file.
Warning: Make sure you have everything you need to put out a fire (a fire extinguisher, plenty of water, thick fabric that doesn't burn easily, such as a blanket made of certain materials) nearby when you work with the bottle, in case problems arise. Consider also wearing protective gloves. And remember that it is better for children and teenagers under 18, as well as people “under the spell”, not to do such things, because they will most likely neglect safety measures.
Add-ons:
Always remember that it is not necessary to “cut” in a straight line. The thread can be wound around an oval at an angle or even secured with adhesive tape (but just do not glue the tape in the path of the thread burning, glue it where the burning should end!) in any other angle, the main thing is to observe the condition of a tight fit of the thread to the glass;
The same can be done with any other glass item, for example, with glass panels, but in this case both sides of the panel must be heated at the same time.
Today, every day it is gaining more and more momentum " Hand Made" creation. Very often, handicraftsmen use glass bottles in their creations. They are used to make vases, lamps, stands, etc.
I'll show you a very simple way to cut a bottle evenly in almost a few seconds.
All we need is nichrome wire, battery 12 V and cold water.
Cutting the bottle
First you need to determine the location of the incision. To make it even, take a piece of paper and wrap it around the bottle. Align the edges of the sheet so that the line is straight. Then take a felt-tip pen or marker and draw a border along the edge of the piece of paper. Now the leaf can be removed.
Next, you need to take a piece of nichrome wire with a diameter of 0.5 mm and attach one end to a stationary object. For these purposes I use a black weight. We immediately attach one wire from the battery to it.
We make a loop around the bottle. And we align it along the mark from the marker.
To avoid getting burned, take the wire with pliers. We tighten it just a little so that the wire is aligned.
Apply voltage to the second end of the wire.
It can be seen that the wire is hot. In places of contact with the bottle, the wire does not completely turn red, since the bottle takes away heat.
We wait without moving the wire and holding it under tension for about 30 seconds.
Then we quickly remove the wire and spray the heating area with water. You can also prepare a bucket of water and dip the bottle in it.
You will hear a peculiar click of the glass, and the bottle will burst exactly along the line where the nichrome wire passed.
The explanation is simple: during heating specific place Internal stress arises in the glass. After sudden cooling, the surface of the glass cools sharply, but its interior remains heated. As a result of such a sharp change, microcracks appear, which instantly turn into splits.
This trick can be done not only with round bottles, but also with square, oval, etc.
