Master class on cutting a bottle with thread
Everyone knows that you can make many useful and original things with your own hands from unnecessary glass bottles. However, not everyone knows how easy it is, because many have no idea how to cut off part of a bottle without a glass cutter. We offer you a master class on how to cut glass bottle using regular thread quickly and easily at home without using a special tool.
In order to cut a glass bottle we will need:
- A piece of regular cotton thread.
- Acetone or alcohol.
- Capacity with cold water.
- Matches or lighter.
The order of cutting with thread
Step 1
Cotton thread soaked in acetone
Using a marker, mark the line along which you want to cut the bottle. We wet the thread in acetone and wrap it several times along the intended line. We tie the rope and cut off its ends.
Tie the thread tightly
Trim the ends of the thread
Step 2
Holding the bottle horizontally over a container of water, set fire to the thread. In this case, the bottle must be rotated to ensure uniform heating.
Set fire to the thread
Step 3
As soon as the thread burns out, you should immediately dip the bottle into a container of cold water. Due to a sharp change in temperature, the glass itself will crack along the line where the rope was.
Dip the bottle in very cold water
Step 4
Separate the two parts of the bottle with your hands
At the last stage, all that remains is to sand the edge with sandpaper or a file. Then, from the resulting glass, you can make an original candlestick or flower vase, decorating the product to your own taste, in general, experiment!
Sand the cut with sandpaper
Decor made from glass bottles, quite popular in lately, and since many are interested in the question of how to cut a glass bottle at home, without using a glass cutter, 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 with 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? Can be used sandpaper or a stone for sharpening 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!
Why throw away glass bottles when you can make amazing ones out of them? decorative elements that will look chic in any interior? If you think that cutting a bottle is very difficult and even dangerous, you are mistaken. There are several simple ways that will help you do this safely so that you can create your own little masterpiece.
How to cut a glass bottle
This video shows 2 ways to cut glass. One of them uses glass cutter, and for the other you only need hot and cold water!
By cutting the bottle into 2 parts, you can make anything out of it: from a candlestick or glass to a hanger for outerwear. The main thing is to have a rich imagination!
Use this advice to add originality to your interior and make it unique. These will definitely decorate your home!

In this publication you will learn how to carefully and evenly use a jar using motor or vegetable oil.
Fill the bowl with cold water to the level where you want to make the cut. We place it in some container, which also needs to be filled with water to the level of water from the container. Now add oil to the bowl until a thin layer forms on the surface of the water. oil crust, which will completely envelop the glass container.
The most important thing is that you should not pour oil straight from the bottle, since the film will be uneven and thus you will not succeed.
Next, to carry out the procedure of cutting a bottle or jar, we will select a piece of metal. The thicker the glass we want to cut, the thicker the metal should be. The glass is quite thin, so the blade of a utility knife fit perfectly. Heat it red hot using a burner or gas stove.
Now lower the hot blade into the bowl just to the oil level.
Remember to protect your skin and eyes from hot splashes!
Due to the quickly heated film, the glass heats up, and due to the temperature difference it cracks. This way we can carefully cut the glass bottle.
As you can see, the chip turned out perfectly smooth.
There are several simple ways to cut the neck of a glass bottle. You may ask why is this necessary? From a beautiful cut bottle you can make a cool glass, a flower vase or a stand for various little things. But before you start cutting beautiful bottles, I still recommend practicing in regular pubs, since this requires experience and some dexterity: it doesn’t always work out the first time.
So, I’ll tell you the most simple ways cut off the neck of a glass bottle.
Method 1 - use a glass cutter
Here you will need a glass cutter. Can be used factory model or make it yourself. Design homemade device may be different: the main thing is that the bottle and the cutting element are securely fixed, but the bottle rotates freely.
Important! When cutting, you need to make one pass: this will ensure the most even edge.
Next, you need to prepare hot (boiling water) and cold (with ice) water. First pour hot water along the cut line so that the glass warms up well.
After this, immediately pour cold water over the bottle.
Due to temperature contraction, the glass should break off along the preliminary cut line. If this does not happen, the procedure must be repeated (douse first with hot and then cold water).
Method 2 - candle flame
This method will require a candle and a piece of ice (you can use a container of very cold water). To break off the neck, draw a straight line on the bottle with a marker, along which the glass warms up well above the candle.
The cutting line is then cooled with ice, after which the glass is cracked by lightly tapping it.
Method 3 - nargev from friction
Another way to break off a bottleneck is to use frictional heating on the glass. To do this, two plastic ties are put on the bottle, which serve as limiters. Three turns of twine are wound between them, after which the twine begins to move forward/backward by the free ends.
After 2-3 minutes, when the glass is sufficiently hot, the bottle is placed in cold water, and when lightly tapped, a chip occurs along the heating line.
If you make a small cut on the bottle with a glass cutter before rubbing with twine, then you do not need to use cold water: the glass will crack when heated on its own.
Method 4 - installation with filament
This method will require a transformer, for example, with microwave oven with the secondary winding removed, instead of which three turns of a powerful power cable are installed.The free ends of the wire are closed through a thick wire. The stand (base) must be heat-resistant and dielectric.
The next step is to connect the transformer to the electrical network. When you turn on the transformer, the filament will heat up: a bottle is applied to it and gradually rotates. When the glass is heated, the neck along the heating line will disconnect, so you need to make sure that the heating is uniform and along the same line.
Method 5 - burning rope
This method requires natural twine and some refined lighter gasoline. A piece of twine is cut to the length required to wrap around the bottle at least 3 times. This piece of string is then soaked in gasoline until it is completely saturated.
Twine soaked in gasoline is wound around the bottle in the place where it is necessary to chip and set it on fire.
When the gasoline has almost burned out, the bottle is lowered into cold water, where the temperature difference causes the glass to burst along the heating line.
