How to cut a bottle? Basic methods of cutting glass and a master class on creating stylish crafts from bottles (75 photos). How to cut a glass bottle with regular thread? Easy and fast! Cutting glass bottles
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 have no idea how to cut off part of a glass bottle without special machine, and 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; removing the top wine bottle or champagne bottles, 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 description of the process below demonstrates, cutting glass is surprisingly easy, and you can always use 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;
- 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);
- a diamond-coated file or fine-grained good 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 at all 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 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 thing, for example, with glass panels, but both sides of the panel in this case must be heated simultaneously.
Today, “Hand Made” creativity is gaining more and more momentum every day. 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, 12 V battery 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: when a certain place is heated in the glass, internal stress arises. After sudden cooling, the surface of the glass cools sharply, and its inner part it stays warm. As a result of such a sharp change, microcracks appear, which instantly turn into splits.
This trick can be done not only with bottles round shape, but also square, oval, etc.
Handicrafts are gaining momentum, and the products made by masters of this field are increasingly pleasing to the eye. Perhaps you've already seen it. What interesting and unusual vases can be made from simple bottles. In this case, there is one important question - how to cut glass bottle so smooth. As practice shows, this is done quite simply, and I will tell you several very interesting ways.
Flame
First we need a glass cutter, a bottle and possible source fire, preferably narrowly directed. To do this, you can take another bottle in which you can light a flame. It is worth noting that cutting bottles with a glass cutter and without using fire is also possible, only in this case you will need to spend much more time.
First you need to make an even cut on the bottle along which you want it to split. This may require tesques or some other type of fixation. You can cut it using a glass cutter, or you can take a drill or screwdriver and insert a nozzle into it for working with glass. The quality of the resulting cut will depend on how smoothly you make the cut.
Now we need to heat up our cut. To do this, the bottle must be gradually scrolled over the flame. A candle is perfect for this. You need to rotate evenly and without jerking so that the surface heats up equally in all places. We do this for about five minutes, after which we dip the bottle into a container of cold water.
It may be necessary to repeat these steps several times until the bottle breaks along the cut line. After this, you just need to process the edges, removing their sharp parts.
Boiling water
The second way to cut a bottle with your own hands again requires a tool for working with glass. Using a glass cutter, you again need to draw a contour along which the cut will have to go. At the same time, it is important to make the cut not only even, but also complete - you should not go to the area where you started, because if the contour overlaps itself, the cut line will turn out uneven.
Now you need to boil water in the kettle. We will gradually water the cut on the bottle with it. When the water has boiled, you can begin the process. The bottle should be watered slowly and carefully - do not go too far from the initial cut.
After you have poured boiling water over the bottle several times, you should immediately place it in cold water. It will not break along the cut the first time; to do this, you need to repeat the procedure several times. Next you also need to process the sharp edges, after which you can do whatever you want with the bottle.
Thread
This may not be the safest way to cut bottles in terms of fire safety, but at the right approach there should be no danger. To do this, you can use a fairly thick yarn thread or a simple cotton cord.
It is important that it is natural, and not synthetic material. Depending on the thickness of the thread, you may need to wrap it around the bottle where the split is needed one to five times.
It is best to take a fairly thick lace, which will be enough for a single ring. After wrapping the bottle, you should cut off the excess ends so that they do not dangle.
Next we take acetone. We need to soak our thread in it, and then put it back on the bottle. It should be well saturated with acetone, this is important for the future part. Now you need to tie the thread, and do it quite tightly, because this can later affect the quality of the cut.
Then you just need to light the thread and slowly scroll the bottle. And again we will need a container with cold water, into which we will need to place the bottle after the thread has almost completely faded. If you did everything correctly, the bottle will split in the place where the thread was. Clean the edges again.
Dremel
Another good way how to cut a glass bottle requires special tool. To do this, you only need to decide on the cut line, for which it would be good to use a simple masking tape. You will need two strips that will go just around the cut line. Next, it will be good to secure the tool and turn it on.
You need to slowly and confidently scroll the bottle along the cut line, while the tool does all the work for you. You will need to turn the bottle at least 3-5 times before it cracks. Next, having processed the sharp edges, you can decorate your cut bottle.
Nichrome wire
Finally, I left a not very simple, but interesting and spectacular way to easily cut a bottle at home. You don't need much for this.
You will need a power source, for which a simple 12-watt battery is well suited, the wire itself, a bottle that needs to be cut, and a container of water in which you can dip the bottle.
To more conveniently determine the cutting line, you can take a glass cutter and carefully draw the direction. Next we take heavy object, which will not catch fire - stone or steel will work well, it will hold the wire on one side. There you will also need to connect the power cable.
We wrap the wire along the cut line, and then grab the second edge with pliers. You need to pull a little so that it stretches a little and becomes smoother. Then we apply voltage and observe a beautiful, but quite dangerous picture - a heated nichrome wire. Half a minute will be enough for such a device to cut almost any bottle.
Hello, dear readers! Decor made from glass bottles, quite popular in lately, by the way, we have already discussed this topic in the review “Bottles in the interior: now we have found a use for them!”, and since many are interested in the question of how to cut a glass bottle at home, without using a glass cutter, I would like to devote today’s master class to 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:
- Glass bottle;
- Wool threads;
- Solvent (you can use kerosene, alcohol, cologne, acetone);
- Scissors or stationery knife;
- Gloves (will protect the skin of your hands from exposure to the solvent);
- Lighter or matches;
- To protect your eyes, just in case, glasses (in fact, there are no fragments, but there is no need to be too careful);
- A deep basin filled with cold water.
So, how to trim a bottle with thread? We take a wool thread, measure it 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 cutting glass is based on a rapid change in temperature, we all know from physics lessons that when heated, 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!

Round glass can serve not only as a vessel for liquid, but also as a source of inspiration. If you know how to cut glass bottles and jars, you can make a lot of amazing things. Starting from glasses and ashtrays, and ending with lamps and designer spatulas, the number of crafts made from recycled materials is limited only by a flight of fancy. It's amazing how original and beautiful things can be made from practically free material. The main thing is the desire to create, and we will talk about the process itself in this article.
Types of glass cutters for bottles
Today there are many ready-made devices for cutting glass jars and bottles. They all have different designs, but according to the type of action they are divided into only two groups: cutting and heating. General principle both groups remain united - the bottle is fixed in a horizontal position and rotates around the glass cutter or heating element. The operating principle of the devices is quite similar, but has some peculiarities.Roller glass cutter for bottles has simple design and is widely used by DIY enthusiasts. Can be assembled with your own hands from available materials. The cost of the finished device varies from several hundred to a couple of thousand rubles. The cut line is fairly straight, but the edges require sanding. The best option for home craftsmen.
Bottle cutter with heating element has more complex mechanism, but also more high quality cutting The device operates from the mains or battery. You can assemble one if you have special knowledge, but at your own peril and risk. Ready-made devices cost several thousand rubles and are unlikely to be of interest most of population. Suitable for creative workshops or designers.
DIY glass cutter for bottles
There is no need to spend money on buying a glass cutter for bottles. This device is very simple, and if you have certain parts and desire, you can make it yourself. Below we will give step-by-step photo instructions on assembling a convenient and practical cutter. You may have to buy some parts, but they cost a penny and are sold in any market or hardware store.
Required materials:
- Wooden base: 25 x 14 x 2
- Side bar: 25 x 4 x 2
- End block (stop): 11 x 4 x 2
- Wooden slats: 25 x 1 x 2
- Roll-out rollers: 4 pcs with a maximum diameter of 4 cm (preferably fixed rollers with rubber coating)
- Cable channel: 25x2 (with minimum thickness)
- Roller glass cutter
- A little PVA glue and a handful of screws
Assembling the device
We will start with the most complex and exquisite stage of the work - assembling the cutting mechanism. Let's take it wooden slats 25 x 1 x 2 and saw off two pieces 3 cm long from it. Carefully make through longitudinal holes in the resulting pieces of wood. They will serve as grooves for installing a hinge on which the guide with the glass cutter will run.
From the same rail, cut off another piece, 9-10 cm long, and arrange all the parts as in the photo below. We cut the cover of the cable channel to length, equal to size three wooden parts(2 pieces of 3 cm each and the width of the slats is 2 cm), approximately 8 centimeters.
At the next stage, we will fix the cutter on the guide. To do this, it is better to make a small recess at the end of the rail, which will serve as a kind of limiter for the glass cutter.
To prevent the wood from cracking when tightening the self-tapping screw, at the attachment point, you should make a hole in advance with a drill of a smaller diameter.
If your self-tapping screw, like the cutter in the photo, has recesses for breaking off glass, then you can use them for fastening. If there are no grooves, or they are located further than the cutting roller, then it is better to drill a mounting hole in the metal head. In general, the main thing is that the glass cutter is installed as in the photo.
After securing the cutter, it's time to put the structure together. To do this, screw two 3 cm bars along the edges of the cable channel cover. We screw hinge screws, no more than 4 centimeters long, into the pre-prepared grooves in the bars (long ones can be cut off). We drill a through hole in the lower part of the guide rail, install it between the bars and fix it with self-tapping screws. In order for the rail to rise, its lower corner must be smoothed using sandpaper or a file. We look at the photo and repeat.
Having finished designing the cutting mechanism, you can proceed to assembly work site future bottle cutter.
First of all, we attach a side block 25 x 4 x 2 to the base. These parts can be connected using self-tapping screws, screwing them in reverse side grounds. You can also use PVA glue or epoxy resin.
When the side part is fixed, you can proceed to installing the roll-out rollers. The first pair of wheels is installed at a distance of 3-4 cm from the upper edge of the base. The next pair is located 12 cm down. For more elongated bottles, you can prepare another set of holes, 5 cm below the second pair of rollers. Pay attention to the photo.
The final stage of assembly will be attaching the lower part of the cable channel to the edge of the side bar, and fitting the end stop with screws or glue.
With a slight movement of the hand, attach the cover with the cutter to the base of the cable channel and the device is ready for use!

How to cut a bottle without a glass cutter
A compact bottle cutter is a very convenient device, but it is made for frequent use. What to do for those for whom this procedure is isolated and will not be repeated in the next decade. Buy finished device It’s expensive, but it takes a long time to assemble and it’s not guaranteed that it will turn out as it should. As you already understood, now we'll talk on how to cut a bottle at home without a glass cutter.This method of glass processing is based on heating with sudden cooling. For a sudden change in temperature, we need a meter of woolen thread, a flammable liquid (acytone, gasoline, kerosene, alcohol), a large container of ice water and, in fact, a bottle. Having prepared all the components, you can get down to business.
Wool thread dip into a container with flammable liquid so that it is completely saturated, and wrap it in a thin line over the place of the future chip. Next, set fire to the thread and wait for it to burn out completely. While burning, hold the bottle horizontally and constantly rotate it so that the fire evenly heats the entire line. As soon as the flame goes out, immediately immerse the bottle in the prepared container with water. After a couple of seconds, the characteristic sound of glass breaking will be heard, signaling the successful separation of the bottle. If there is no click within 5 seconds, you can apply a little force and try to break it.
The above technique can be successfully used for controlled chipping of most types of glass containers, but sometimes there are exceptions. The effectiveness of the temperature difference largely depends on the strength of the glass.
