How to cut a bottle with a thread. Master class: how to cut a bottle with a thread - it's simple! Glass bottle products

There are several easy ways to cut the neck of a glass bottle. Why is this necessary, you ask? From a beautiful cropped 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 at ordinary beer houses, since this business requires experience and some skill: it doesn’t always work out exactly the first time.

So, I will tell you the simplest ways to cut off the neck of a glass bottle.

Method 1 - use a glass cutter

This will require a glass cutter. You can use the factory model or make your own. The design of a home-made device can 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 provide the most even edge.
Next, you need to prepare hot (boiling water) and cold (possible with ice) water. First, pour hot water along the cut line so that the glass warms up well.

After that, immediately pour the bottle with cold water.

From the temperature contraction, the glass should break off along the line of the preliminary cut. If this does not happen, the procedure must be repeated (pouring 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, a straight line is drawn on the bottle with a marker, along which the glass warms up well over the candle.

Then the cut line is cooled with ice, after which the glass breaks with a light tap.

Method 3 - nargev from friction

Another way to break off a bottleneck is to use frictional heating of 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 heated, the bottle is placed in cold water, and with light tapping, a break occurs along the heating line.

If you make a small incision with a glass cutter before rubbing the twine on the bottle, then you do not need to use cold water: the glass will crack when heated on its own.

Method 4 - filament installation

This method will require a transformer, for example, from a 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 the transformer is turned on, the thread will heat up: a bottle is applied to it and gradually rotates. When the glass is heated, the neck will detach along the heating line, so you need to ensure that the heating is uniform and along one line.

Method 5 - burning rope

This method will require natural twine and some refined gasoline for lighters. A piece of twine is cut off to the length necessary to wrap around the bottle at least 3 times. Then this piece of twine is soaked in gasoline so that it is completely soaked.

The twine soaked in gasoline is wound around the bottle in the place where it is necessary to chip and set on fire.

When the gasoline almost burns out, the bottle is lowered into cold water, where the glass bursts along the heating line due to the temperature difference.

Method 6 - use specialized equipment

This method is to use an electric tile cutting machine. The diamond blade cuts thick glass well and evenly. It is recommended to work with gloves, a protective mask and goggles, as glass dust is very dangerous. The advantage of using a cutter is the ability to cut the bottle into small washers, which is not available with other methods.

You will need

• - several bottles of the required size;
• - twine soaked in kerosene or gasoline;
• -copper wire and fire source (lighter, gas burner, etc.);
• -nichrome wire and clothespin;
• - pliers, file or whetstone; - cotton gloves.

Instruction

Take two glass bottles of the required size. It's better to do this for a number of reasons. If in the future you plan to use both parts of the bottle, then after the cutting and grinding procedure, you will have a better chance of getting exactly what you intended. In any case, a little experience is desirable for the success of this operation. Traditionally, a diamond is used to cut glass. But for cutting bottles in they are not always effective. Depending on the material you have at your disposal, try one of the following methods.

Fill the bottle with water to the level where you want to make the cut. Tie the bottle with twine moistened with gasoline or kerosene, according to the level of the poured water. Do not allow the twine to sag - it should fit very tightly against the walls of the bottle at water level. Light the twine. The bottle should burst exactly along the twine line.

Take a thick copper wire in order to cut the glass bottle in the second way. Wrap it tightly around the bottle in the place where you want to get a cut. There should be no gaps between the wire and the bottle. Prepare a container of cold water. Use a lighter or torch to heat the loose ends of the wire. At the moment when the wire is hot, lower the bottle into cold water. The bottle should burst along the wire line.

Mount the electric glass cutter. This is a fairly capacious process, but it can be used to get the highest quality cut on large-diameter thick glass bottles. At a wooden clothespin, sponges are treated with asbestos. Nichrome wire with a diameter of about 0.5 mm will serve as a spiral. It is necessary to cover the vessel being cut with it, and fasten the ends of the spiral between the clothespins so that they do not connect. Put ceramic insulators or porcelain beads on the free ends. Connect the ends with mounting wires of the MGShV type with a cross section of 0.5-0.75 sq. mm and connect to a step-down transformer with a voltage on the secondary winding of 10-12 V. In its absence, you can use a car battery. As soon as the wire warms up, a crack forms at the point of contact with the glass, along which the vessel can be easily split.

Finish the cut surface. If sharp chips have formed, they can be gradually crushed with pliers, then file the surface. Finally, grind the edge of the bottle with a whetstone or fine sandpaper.

note

Use cotton gloves when handling glass.

Helpful advice

When finishing the edges of the bottle, the tools become dull very quickly, so it is advisable to use bars and files that have already been in use.

If the neck of a plastic bottle can be cut off with an ordinary knife or scissors, then it will take skill and skill to evenly separate the neck from a glass bottle. From a glass bottle with a cut off neck, you can make a pretty vase, glass or ashtray.

Instruction

Take the glass cutter. Glass cutter must be diamond. Scratch them to the desired circular or curly line. Wrap the bottle in a thin towel. Tap the scratched area with a small hammer. The throat will separate from the bottle.

Take a grinder and call an assistant. This operation is necessary. Turn on the grinder and let the assistant press it to the table. Make the necessary scratch on the bottle by pressing it against the spinning disk of the grinder and slowly turning it. Wrap the bottle in a towel and tap it. The throat will separate.

Make ice water in the refrigerator. Pour it into the bottle up to the place where you want to make a cut. Pour 30 milliliters of kerosene on top and set it on fire. The neck of the bottle will fly off by itself due to the sharp temperature difference. The cut in this case is very even. Gasoline in this case is strictly prohibited!

Prepare with ice water. Wrap the bottle with thread in several layers in the place where the cut is needed. Moisten the thread with gasoline or pure alcohol and set it on fire. When the thread burns out, quickly lower the bottle into ice water. The throat will separate due to the temperature difference.

Soak the empty bottle for 20 minutes in the freezer of the refrigerator. Wrap a piece of nichrome wire with a resistance of at least 75 ohms around the bottle in a half loop where a cut is needed. Connect the ends of the wire to a 220 volt network. When the wire is hot, the throat will fly off due to the temperature difference.

Roughen the surface of the bottle with sandpaper where a cut is needed. Take a graphite pencil. Graphite should be soft. Draw a circular line where you want the cut. Do not close the line to the end, leave a gap of 5 millimeters. Cool the bottle in the freezer. Then connect 220 volts to the ends of the line drawn with graphite where there is a gap. The neck of the bottle will fly off due to the temperature difference.

Always follow safety precautions. All work with glass is carried out with gloves on. Eyes must be protected with special goggles. Do not perform such work in the presence of children. Perform any work with fire only on the street. Keep a fire extinguisher close at hand.

An ordinary glass bottle can be successfully used in the household. For example, from such a container you can get a pretty pretty vase for flowers. It's just a pity that only one flower can fit in a narrow neck. It does not matter, because if you wish, you can solve this problem. To do this, you need to cut the bottle, or rather, carefully divide it into parts.

You will need

• - an empty glass bottle;
• - rope;
• - gasoline or kerosene;
• - copper wire;
• - bucket;
• - cold water;
• - candle;
• - matches (lighter);
• - file;
• - wire cutters;
• - pliers.

Instruction

Take a glass bottle and tie it with a thin string at the level at which you want to divide it. Pre-moisten the rope with plenty of kerosene or gasoline. When choosing a rope, try not to make it too thick. As a last resort, use woolen thread. The thinner the string, the tighter it will adhere to the glass surface, which will provide a more even cut.

Pour cold water into the bottle so that it reaches exactly the level of the future incision. Make sure the string and water level match. If necessary, adjust the rope so that it fits the bottle evenly around the entire diameter.

Using a match or a long wooden stick, set fire to the rope. When the fire covers it completely, a temperature difference is formed (outside there will be a high temperature from burning, and inside you will have cold water). The collision of hot and cold will cause the glass to burst along a line corresponding to the water level.

When using the second method, draw water. Wrap the bottle around the line of the intended cut with thick copper wire, leaving a short tip. With the help of a candle flame, begin to heat this free tip. Gradually, the entire wire will become hot. Now quickly and carefully lower the bottle into the bucket of water. If everything is done correctly, the glass will burst exactly in the place where the heated wire is located. This method is safer than the one described above.

If the edges of the bottle after such cutting are not too smooth, process them with wire cutters or pliers, and then grind them with a whetstone or file with a fine notch. When processing, moisten the file with water from time to time. Do not move the file randomly, but along the glass cut. Be careful not to cut your hands on the glass. Use a bottle cut in one of the ways described as a decorative vase.

• How to "cut" a glass bottle

From a bottle, decorating it, you can make a stylish vase, but you just need to cut off its neck. The original idea belongs to the craftswoman Jordan, who uses only cotton thread and acetone or nail polish remover.

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.

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.

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 from it: from a candlestick or a glass to a hanger for outerwear. The main thing is to have a rich imagination!

Today, “Hand Made” creativity is gaining momentum every day. Very often, needleworkers use glass bottles in their creations. They make vases, lamps, coasters, etc. out of them.
I will show you a very simple way to cut a bottle cleanly in almost a few seconds.

All we need is nichrome wire, a 12 V battery and cold water.

We cut the bottle

First you need to determine the location of the incision. To make it even, take a piece of paper and wrap the bottle around it. Align the edges of the sheet so that the line is even. Then take a felt-tip pen or marker and draw a border around the edge of the sheet. Now the leaf can be removed.

Next, you need to take a piece of nichrome wire with a diameter of 0.5 mm, 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 coil around the bottle. And align to the trail of the marker.

In order not to get burned, take the wire with pliers. Pull just a little to straighten the wire.
Apply voltage to the other 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, as the bottle takes away heat.

We wait without moving the wire and holding it in tension for about 30 seconds.
Then we quickly remove the wire and sprinkle the place of heating with water. You can also prepare a bucket of water and dip the bottle into it.

You will hear a peculiar click of glass, and the bottle will burst exactly along the line where the nichrome wire passed.

Everything is explained simply: during the heating of a certain place in the glass, internal stress arises. After a sharp cooling, the surface of the glass cools sharply, while its inner part remains heated. As a result of such a sharp change, microcracks appear, which instantly turn into a split.

Such a trick can be done not only with round bottles, but also with square, oval, etc. bottles.
