How to cut the neck of a glass bottle. How to cut a glass bottle with a regular thread? Easy and fast! Types of glass cutters for bottles

In this publication, you will learn how to neatly and evenly or a jar using motor or vegetable oil.

We fill the dishes with cold water to the level where we want to make a cut. We place it in some container, which also needs to be filled with water to the level of water from the vessel. Now add oil to the bowl until a thin oil crust forms on the surface of the water, which will completely envelop the glass container.

The most important thing is that you should not pour oil straight from the bottle, because the film will turn out to be uneven and thus nothing will come of it.

Next, to carry out the procedure for cutting a bottle or jar, we will select a piece of metal. The thicker the glass we want to cut, the thicker the metal must be. The glass is quite thin, so the blade of a clerical knife fit perfectly. We heat it red-hot with a burner or gas stove.

Now we lower the hot blade into the bowl only to the oil level.

Remember to protect your skin and eyes from hot splashes!

Due to the rapidly incandescent film, the glass heats up, and due to the temperature difference it cracks. So we can carefully cut the glass bottle.

As you can see, the chip turned out perfectly even.

Why throw away glass bottles when you can make delicious ones out of them. decor 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 a few easy ways to help you do this safely so you can create your own little masterpiece.

Types of glass cutters for bottles

To date, there are many ready-made devices for cutting glass jars and bottles. All of them have a different design, but according to the type of action they are divided into only two groups: cutting and heating. The general principle of both groups remains the same - the bottle is fixed in a horizontal position and rotates around the glass cutter or heating element. The principle of operation of the devices is quite similar, but has some features.

The roller glass cutter for bottles has a simple design and is widely used by homemade lovers. Can be assembled with your own hands from improvised means. The cost of the finished device varies from a few hundred to a couple of thousand rubles. The cut line is quite even, but the edges require grinding. The best option for home craftsmen.

A bottle cutter with a heating element has a more complex mechanism, but also a higher cut quality. The device is powered by mains or battery. You can assemble this, 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 to most of the population. Suitable for creative workshops or designers.

DIY bottle glass cutter

It is not necessary to spend money on buying a glass cutter for bottles. This device is very simple, and if you have certain details and desire, you can do it yourself. Below, we will give a step-by-step photo instruction for 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 (limiter): 11 x 4 x 2
• Wooden lath: 25 x 1 x 2
• Roll-out rollers: 4 pcs with a maximum diameter of 4 cm (preferably non-rotatable with a rubber coating)
• Cable channel: 25x2 (with minimum thickness)
• Roller glass cutter
• A little PVA glue and a handful of screws

Device assembly
We will start with the most difficult and jewelry stage of work - the assembly of the cutting mechanism. We take a wooden rail 25 x 1 x 2 and saw off two pieces from it, 3 cm long. In the resulting pieces of wood, carefully make through longitudinal holes. They will serve as grooves for installing the hinge, on which the guide with the glass cutter will go.

From the same rail, cut off another piece, 9-10 cm long, and arrange all the details as in the photo below. We cut the cover of the cable channel to a length equal to the size of three wooden parts (2 pieces of 3 cm each and a rail width of 2 cm), by about 8 centimeters.

In the next step, we 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 the self-tapping screw is screwed in, at the attachment point, a hole should be made in advance with a drill of a smaller diameter.

If on your self-tapping screw, as well as on the cutter with a photo, there are notches 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 assemble the structure together. To do this, we fasten two bars of 3 cm along the edges of the cable channel cover. In pre-prepared grooves in the bars, we twist self-tapping hinges, no more than 4 centimeters long (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 out with sandpaper or a file. Look at the photo and repeat.

Having finished with the design of the cutting mechanism, you can proceed to the assembly of the working platform of the future bottle cutter.
First of all, we attach a 25 x 4 x 2 side bar to the base. You can connect these parts with self-tapping screws by screwing them on the back of the base. You can also use PVA glue or epoxy.

When the side part is fixed, you can proceed to the installation of roll-out rollers. The first pair of wheels is installed at a distance of 3-4 cm from the top edge of the base. The next pair is located 12 cm down. For longer bottles, another set of holes can be prepared, 5 cm below the second pair of rollers. Pay attention to the photo.

The final stage of the assembly will be the fastening of the lower part of the cable channel to the edge of the side bar, and the landing of the end stop on self-tapping screws or glue.

With a slight movement of the hand, we 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 unique and will not be repeated in the next decade. It is expensive to buy a ready-made device, and it takes a long time to assemble it and it’s not a fact that it will turn out as it should. As you already understood, now we will talk about how to cut a bottle at home without a glass cutter.

This method of glass processing is based on heating with rapid cooling. For a sharp change in temperature, we need a meter of woolen thread, a flammable liquid (acetone, 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.

We dip the woolen thread into a container with a flammable liquid so that it is completely saturated, and wind it with a thin line at the place of the future chip. Next, we set fire to the thread and wait for it to completely burn out. While burning, we 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 a prepared container of water. After a couple of seconds, a characteristic sound of broken glass will be heard, signaling the successful separation of the bottle. If there was no click in 5 seconds, you can apply a little force and try to break it.

The above technique can be successfully applied to the controlled breaking of most types of glass containers, but sometimes there are exceptions. The effectiveness of the temperature difference depends largely on the strength of the glass.

For those who want to see with a more illustrative example how to cut a glass bottle at home without a glass cutter, we recommend watching the following video.

Hello dear readers! The decor of glass bottles has been quite popular lately, by the way, we have already considered this topic in the review "", 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 dedicate today's master class in a simple but interesting way, cutting bottles with a thread ...

In this connection, the topic of this master class is “How to cut a bottle with a thread - nothing complicated!”.

For work we need:

1. Glass bottle;
2. Woolen threads;
3. Solvent (you can kerosene, alcohol, cologne, acetone);
4. Scissors or stationery knife;
5. Gloves (will protect the skin of the hands from exposure to the solvent);
6. Lighter or matches;
7. To protect the eyes, just in case, goggles (in fact, there are no fragments, but caution is never superfluous);
8. Deep basin filled with cold water.

So, how to cut a bottle with a thread? We take a woolen thread, measure and cut it in such a way 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 it is planned to make an “incision”. You can simply wrap the thread or tie it in a knot, in this master class I just wrapped it.

After that, we set fire to this thread with matches or a lighter, and it is better to keep the bottle in an inclined position - strictly horizontally (parallel to the ground), gently scrolling around the axis.

The fire will burn for about 30-40 seconds, as soon as the lit thread goes out - quickly lower the bottle into the 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 the lessons of physics that glass expands when heated, and narrows when cooled, respectively, with a sharp change in temperature, a kind of destruction of glass occurs and it simply cracks!

Needlework is gaining momentum, and the products that the masters of this sphere make are more and more pleasing to the eye. Perhaps you have already seen. What interesting and unusual vases can be made from simple bottles. In this case, there is one important question - how to cut a glass bottle so evenly. As practice shows, this is done quite simply, and I will tell you some very interesting ways.

Flame

To begin with, we need a glass cutter, a bottle and a possible source of fire, preferably a narrow one. To do this, you can take another bottle in which you can make a flame. It is worth noting that cutting bottles with a glass cutter and without using fire is also possible, only in this case it will take much more time.

First you need to make an even cut on the bottle, along which you want it to split. This may require tees or some other type of fixation. You can cut with 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 exactly you make the incision.

Now we need to heat our incision. To do this, the bottle must be gradually scrolled over the flame. This is perfect for a candle. It is necessary to rotate evenly and without jerks, 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 splits along the cut line. After that, you just need to process the edges, removing their sharp parts.

Boiling water

The second way to cut the bottle with your own hands again requires a glass tool. With a glass cutter, you again need to apply the contour along which the cut will have to go. At the same time, it is important to make the incision not only even, but also complete - you should not find the area from which you started, because if the contour overlaps itself, the cut line will turn out to be uneven.

Now you need to boil water in the kettle. We will gradually water the incision on the bottle with it. When the water boils, you can start the process. The bottle should be watered slowly and carefully - do not go far with water from the original incision.

After you have poured boiling water over the bottle several times, it must immediately be placed in cold water. From the first time it will not break along the cut, for this you need to repeat the procedure several times. Next, you also need to process the sharp edges, after which you can do anything with the bottle.

A thread

This may not be the safest way to cut bottles from a fire safety point of view, but with the right approach, no danger should arise. To do this, you can use a fairly dense thread for yarn or a simple cotton cord.

It is important that it is natural, not synthetic material. Depending on the thickness of the thread, you may need to wrap it around the bottle at the desired split one to five times.

It is best to take a sufficiently dense lace, which will be enough for a single ring. Having wrapped the bottle, it is worth cutting off the excess ends so that they do not hang out.

Next up is 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 make it tight enough, because this may later affect the quality of the cut.

Then you just need to set fire to the thread and slowly scroll the bottle. And again, we need a container with cold water, in which we will need to place a bottle after the thread has almost completely faded. If you did everything right, the bottle will crack in the place where the thread was. Clean up the edges again.

Dremel

Another good way to cut a glass bottle requires a special tool. To do this, you only need to decide on the incision line, for which it will 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 fix the tool and turn it on.

You need to slowly and confidently scroll the bottle along the notch line, while the tool will do all the work for you. You will need to rotate the bottle 3-5 times at least before it cracks. Further, 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, the bottle that needs to be cut and a container of water into which you can dip the bottle.

For a more convenient definition of the cut line, you can take a glass cutter, which carefully draw the direction. Next, we take a heavy object that will not catch fire - stone or steel is well suited, it will hold the wire on one side. You will also need to connect the power cable there.

We wrap the wire along the notch line, after which we take the second edge with pliers. You need to pull a little so that it stretches a little and becomes smoother. Then we give voltage and observe a beautiful, but rather dangerous picture - a heated nichrome wire. Half a minute will be enough for such a device to cut almost any bottle.
