Scissors

It is worth making a reservation right away. the technique allows you to cut thin glass, no more than four millimeters. When working, it is recommended to wear safety glasses and protect your hands with gloves. You will need a container with water, in which, in fact, everything will happen.

Water acts as a lubricant, allowing you to cut the desired shape with scissors. Whichever tool you hit will not work. you need something serious, like a tailor’s scissors. Cutting is carried out according to the previously applied markings. The cutting force is comparable to what is needed when working with hardboard.

Another nuance: the container must be deep enough so that the layer of water above the glass immersed in it is large. How much is verified empirically, first you should experiment with an unnecessary piece of glass.

How tempered glass is cut

The difference when processing ordinary and tempered glass is only in the fragility of the latter. The technique with a grinder and a diamond disc is suitable, but you need to work extremely carefully. The method with a soldering iron can also come in handy (depending on the thickness of the material), and you definitely won’t get a trick with water and scissors.

Suitable methods for cutting plexiglass

The easiest way, without further ado, is to take an ordinary hacksaw for metal and make a neat cut according to the markings. You can use a grinder (if you know how to handle it).

If you need to perform curly cutting, you have to be sophisticated: a nichrome thread is connected to a 24 volt transformer, voltage is applied to it, and it burns a path of the desired shape in the plexiglass.

Twine

The point of the technique is to first heat the glass to be cut, and then cool it sharply. Under the influence of the temperature difference, it will burst along the line of greatest contrast. The method is good if you need, for example, to cut a glass bottle or jar.

To do this, you need to soak the woolen thread in alcohol, acetone, white spirit or some other flammable liquid. The string is wrapped around the intended victim and set on fire. Then it is rapidly cooled with running water. If successful, you will hear a characteristic click. If it did not work out the first time, you need to repeat the ritual.

The technique may not work on thick-walled bottles, such as the Champagne Faustpatron. In the process of experiments, it is good to stock up on a fire extinguisher, otherwise the results can be very surprising, up to the arrival of the Ministry of Emergency Situations and an ambulance.

Soldering iron

A straight cut is not always needed, and a file with a soldering iron will help out in this situation. No soldering iron. a wood burning device will do.

The process is lengthy, but creative. To begin with, mark the glass and mark the cutting line on it with a marker. Then, from the edge, at the beginning of the mark, a groove is made with a file, which will serve as a guide. Having retreated a couple of millimeters along the line, the glass is heated with a soldering iron until a crack appears from the groove to the heating point. Then another couple of millimeters retreat and repeat the process.

To make things go a little faster, the glass can be cooled with a damp cloth or dishwashing sponge.

How to cut glass at home without a glass cutter

Cutting glass with a professional tool is easy and convenient (especially after a number of unsuccessful attempts). But, firstly, not everyone has a glass cutter. And secondly, in the case of a one-time promotion or rare use, is it needed at all? After all, a professional tool costs a lot, and a cheap Chinese one can sadden you with its “quality and durability.” And the result of the work too. Therefore, I propose to use techniques that make it possible to do almost without costs, and even eat a fish, and not choke on a bone.

How to make a hole for the handle

There are several options. either drill with a drill with a victorious nozzle, organizing a plasticine bath with camphor and turpentine on the surface, or using the thermal method. To do this, wet river sand of a fine fraction is applied to the glass, and with the help of a sharpened rod, a funnel is made in it, where molten solder or lead is dripped. After a couple of minutes, the sand and solder are removed.

Maybe someone will consider the list of methods incomplete. we have a lot of Kulibins, and there are many more options for solving the problem. But the advantage of the described methods, and bold, is that they work.

We cut the bottle

Lifting the bottle up, we pull the nichrome wire. At the same time we connect the second end of the wire with the other pole of the battery with pliers and also pull it.

The wire starts to warm up, as evidenced by the bright red edges. In the places where the wire touches the bottle, the process of heat transfer takes place, therefore the wire is not so bright.

We heat the glass, without loosening the wire, for at least half a minute. During this time, the glass will have time to warm up inside.

Then we remove the wire and quickly spray the place of heating with cold water (or lower the bottle into a container of water). The characteristic click of the shattered glass is heard. The result is on the face.

We cut a square bottle in the same way, trying to ensure maximum contact of the wire with the glass along the cut line.

If, after wetting with cold water, the top of the bottle does not fall off by itself, just gently pull on the neck.

Remove any irregularities and notches along the edge of the cut with sandpaper. To avoid cuts, all glass handling operations must be carried out with protective gloves.

Materials for work

In order to cut a glass bottle, you will need:

  • glass bottles that need to be cut;
  • 12 V battery;
  • a piece of nichrome wire;
  • spray bottle or container with cold water;
  • paper;
  • marker;
  • insulated wires;
  • cargo;
  • pliers;
  • sandpaper.

How to cut a glass bottle at home without a glass cutter

Recently, it has become very fashionable to use various decor from glass bottles in the home interior. These are vases, and candlesticks, and pots for flowerpots, and various kinds of lamps. They even make wine bottle tables. There are many uses. There is only one problem, how to cut a glass bottle at home and still get a perfectly straight edge? We will tell you about this in our article. The method is very fast and suitable for any glass bottle shape.

Preparing the cut line

Having wrapped the bottle in the right place with a sheet of paper, draw a line with a marker at the same time along the edge of the paper and the bottle. With this method, you will get a perfectly straight line.

We connect one end of the nichrome wire to one of the poles of the battery. We attach a load to the junction to ensure the tension of the wire.

We wrap the bottle with wire along the line drawn earlier.

Workshop on cutting a bottle with thread

Everyone knows that you can make many useful and original things from unnecessary glass bottles with your own hands. However, not everyone knows how easy it is, because many do not know how to cut off a part of the bottle without a glass cutter. We offer you a master class on how you can cut a glass bottle using a regular thread quickly and easily at home without using a special tool.

  • 1 Tools
  • 2 Thread cutting procedure
  • 2.1 Step 1
  • 2.2 Step 2
  • 2.3 Step 3
  • 2.4 Step 4

Step 2

Holding the bottle in a horizontal position over a container of water, we set fire to the thread. In this case, the bottle must be rotated to ensure uniform heating.

Step 1

Cotton thread dipped in acetone

Mark with a marker a line along which you want to cut the bottle. We moisten the thread in acetone and wrap it several times along the marked line. We tie the rope and cut off its ends.

Tie the thread tightly

Cut off the ends of the thread

Step 3

As soon as the thread burns out, immediately you need to dip the bottle in a container of cold water. From a sharp temperature drop, 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, it remains only to process the edge with an emery or a file. Further, from the resulting glass, you can make an original candlestick or a vase for flowers, decorating the product to your own taste, in general experiment!

How to cut a glass tube at home

Few people know how to cut a glass tube and what kind of tool is needed for this. Read about this in our article.

To cut a glass tube, you can use the following technique. Wrap the place of the tube where you want to cut with a wide strip of paper. The length of the paper should be such that it wraps the tube 5-6 times. The ends should be glued together. [blockquote_note] Make sure that the edge of the folded paper matches the intended cut. [/ blockquote_note] Next to the same, glue the second strip of paper. Between them there should be a very small space of open glass of the same width around the circumference, where the cut should go. The strips of paper can be slightly dampened before wrapping. Then the narrow space between the strips must be held over a fire (alcohol burner or a cylinder of a kerosene lamp), so we suggest purchasing burners.

The tube is rotated over the fire until the line of unprotected glass between the strips of paper warms up so much that a drop of water released into this place causes a smooth and clean cut. The strips of paper wrapped around the glass tube prevent heat from reaching closed surfaces. Therefore, the fire acts especially strongly on the unprotected glass line.

[blockquote_fact] Before directing the glass tube into the flame, the strips of paper wrapped around the tube must be thoroughly dried. [/ blockquote_fact] Because moisture on the glass can cause it to break along the wrong line.

One Reply to “Cutting Glass Tubes”

And the paper will not light up when we hold a small uncovered strip with a fire?

To cut a glass tube of small diameter, it is placed on the edge of the table on some soft and even lining. a piece of cardboard or a notebook (Fig. 58, a) and a sharp edge of a small triangular file make a scratch across it. This scratch should be a continuous line and should be located about one-sixth of the tube’s circumference. Then the tube is taken with both hands, with a scratch away from oneself, so that the thumbs rest against the tube on both sides of the observed break point. Slightly stretching the tube to the sides, break it with a quick movement, for which the right side of the tube is turned clockwise, and the left side is against it.

In the absence of a file, the glass tube can be cut in a very common way. To do this, the tube is wrapped with two wide strips of moistened paper so that a narrow gap remains between them in the place where the tube is to be cut. The glass in this gap is heated over an alcohol lamp or gas burner, while rotating the tube so that the glass is well heated from all sides. Then a drop of cold water is put into the gap, and the tube is divided into two parts.

The sharp edges of the tube are sanded with a file or emery cloth. You can slightly melt them in the flame of an alcohol lamp or gas burner.

Method two. Fire hazardous.

For work we need:

  • Glass bottle;
  • Woolen threads;
  • Flammable liquid (solvent, kerosene, alcohol, cologne, acetone, etc.);
  • Scissors or utility knife;
  • Gloves (to protect the skin of the hands from the effects of solvents and cuts);
  • Lighter or matches;
  • To protect the eyes, glasses (in fact, there are no fragments, but there is no unnecessary caution);
  • Deep bowl filled with cold water.

So how do you cut a bottle with string? We take a woolen thread, measure and cut it in such a way that it is enough for 3-4 bottle turns. We immerse the measured and cut thread in the solvent, and immediately wrap the bottle in the place where it is planned to make the “cut”. The thread can be simply wrapped or tied in a knot.

After which 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), carefully scrolling around the axis.

After the fire goes out, immediately place the bottle in ice water.

The glass will burst on the heating line due to the temperature difference.

After that, we process the sharp edges with emery paper, a fine file or a sharpening bar.

On a note. You can grind the edges by immersing the glass in water, so you avoid getting glass chips in your eyes, on your skin, on furniture, clothes, etc.

Method 4. installation with filament

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 filament becomes hot: a bottle is applied to it and gradually rotates. When the glass warms up, the neck will detach along the heating line, so you need to make sure that the heating is uniform and in one line.

6 ways to cut a glass bottle evenly

There are several easy ways to cut the neck of a glass bottle. Why is this necessary, you ask? From a beautiful cut bottle you can make a cool glass, a flower vase or a stand for various little things. But, before starting to cut beautiful bottles, I still recommend practicing in ordinary beer halls, since this business requires experience and some skill: it does not always work out the first time.

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

The first way is to trim the bottle. Using a glass cutter.

We select or make an improvised corner stop, put the bottom of the bottle into it and slowly rotate it. A cutting line is drawn with a glass cutter. Read how to use the glass cutter here. It is important that the beginning and end of the cutting line coincide.

Important! All manipulations with glass must be carried out with protective gloves and glasses.!

Then we place the bottle in a container with ice water and pour boiling water into it through a funnel. Due to the sharp temperature drop, the glass at the cut site will burst exactly along the seam.

We carefully remove the bottle from the water. Be careful, there may be sharp notches in the cut line. The edges need to be processed either with a small file or with sandpaper screwed onto a wooden block. Wearing safety glasses is mandatory.

If necessary, the neck of the bottle can be cut in the same way.

As a result, you can make such a nice lamp.

Method 1. use a glass cutter

You will need a glass cutter here. You can use a factory model or make it yourself. The design of a homemade device can be different: the main thing is that the bottle and the cutting element are securely fixed, but the bottle rotates freely at the same time.

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 (you can with ice) water. First, spill hot water along the cutting line so that the glass warms up well.

After that, we immediately pour over the bottle with cold water.

From the temperature reduction, the glass must break off along the preliminary cut line. If this does not happen, the procedure must be repeated (first pour hot and then cold water).

Method 3. friction nargev

Another way to break off a bottleneck is to use frictional heating of the glass. For this, two plastic ties are put on the bottle, which serve as stops. Three turns of twine are wound between them, after which the twine at the free ends begins to move forward / backward.

After 2-3 minutes, when the glass is sufficiently heated, the bottle is placed in cold water, and with a light tap, a spall occurs along the heating line.

how to cut glass tube without glass cutter tool at home ( New method )

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

Stretching the tubes

If we need to get a tube with a narrowed section, then after heating it, it is enough to stretch the tube by its ends. It should also be taken into account that the temperature and speed of stretching the tube affect the result. a short or long section with a changed cross-section is obtained.

If we need to get a tube with a drawn end, then we will do this: Heat the tube until it softens, remove it from the flame and stretch it, and then cut off a part of the tube from the place of the constriction formed. We get a very thin and sharp end of the tube. The slower the glass tube is stretched, the thicker the edges remain, which can prevent the appearance of very thin walls. Also, the stretching of the tubes should be carried out with their continuous rotation in the flame for uniform heating of the stretched zone.

If we need to close the tube at one end, then we need to stretch in a flame and quickly enough. In this case, the resulting thin capillary can be easily melted. After melting the end of the tube, you can slightly blow in it so that a small cavity forms at the end of the tube.

Cutting glass tubes

Cutting glass tubes

Sometimes it is necessary to cut the glass tube, change its shape or length, while maintaining the maximum wall thickness and smooth edges (without protruding sharp debris).

Cutting glass tubes

This can be done effortlessly at home using a gas burner or candle. It must be remembered that ordinary glass is not crystalline. but an amorphous substance. that is, a very viscous substance. Glass does not have a strictly defined melting point, for example. like metals. With a gradual increase in temperature, the glass heats up, softens, then gradually loses its shape and turns into a viscous fluid liquid.

To work with glass tubes of small diameters (the size of a pencil or felt-tip pen), bending of glass tubes is carried out at a temperature of about 450 0 C. To bend glass tubes made of laboratory glass, a high temperature is required. 600 0 С and above.

So cutting glass tubes.

Bending glass tubes

Take the glass tube in that place. where you need to cut it, we will make a small file with a small file (we will create a condition for the development of a crack) around the circumference of the tube. Next, we take the tube from 2 sides as close as possible into the incision and break it at the same time stretching it to the sides. Remember to wrap the tubing in a cloth to avoid damaging your hands with debris.
After cutting the tube, it is necessary to melt its edges, for which you can place the end of the tube in the flame of the burner or hold it over a candle.

To use glass tubes in chemical reactions, a rubber stopper or hose is put on the end of the tube, after having lubricated the end of the tube with glycerin. When cutting a glass tube with thick walls, an annular initial notch is also made, then this area is evenly heated over the candle or burner, but not until softened! You can drop a drop of cold water into a heated place. In this way, the development of the appearance and development of an annular crack can be initiated, after which the tube itself must break in the notch zone.

Bending glass tubes

Bending glass tubes

How to Cut Glass Tubing

Now let’s try to bend the glass tube. To do this, of course, we will heat it up, but not until it is completely softened, but so that holding it by one end, the other end bends under its own weight. We take the tube out of the flame, bend it. that’s all!
But this method of bending glass tubes will not be entirely correct, because when bending, local thinning is formed. Therefore, it is better to do this: you need to heat the glass tube evenly around the entire circumference, take into account the heating of the zone near the bend. Slowly rotating the tube can achieve a much better result.!

When bending glass tubes with thicker walls, you need to close one end of it with a lid, and when the tube bends, very carefully, so as not to form holes, blow air into the tube. After bending the glass tubes while they are still hot, they should not be placed on cold supports, especially in places where they are folded. This leads to cracks. For these purposes, a wooden stand is best suited. In any case, it is best to lay the tubes so that the heated area does not touch objects.

Soldering glass tubes

To solder glass tubes, it is necessary to heat them well (until they soften and show the properties of fluidity of the glass).

Soldering glass tubes

This is a more complex operation than just cutting or bending glass tubes. To solder the tubes, beforehand, their respective ends after heating must be slightly expanded to obtain the appearance of a funnel. This can be done with a graphite rod. If glass tubes of different diameters are soldered, then the end of one tube must be narrowed (this happens in a flame), the end of the other must be heated, then both are applied to each other. Further heating of the joint zone and a slight blowing of air into the tubes will allow aligning the resulting seam.

When soldering glass tubes, a hole in the tube can be created, which is brazed with the melted end of a glass rod without much effort. It must be remembered that in case of insufficient heating of the deformation zone, cracks appear during bending, stretching and soldering of glass tubes at the time of cooling.

Sometimes you have to connect two tubes not at the ends, but, for example, in its central part. It’s not hard to do. You need to heat the tube in the place where you plan to get the hole. When the tube is hot enough, close one end of the tube tightly, for example with a stopper. We will blow at the second end. When air is blown into the area where the tube has been heated, a very thin-walled glass bubble will form. If you carefully pierce such a bubble with a glass rod, then we get a fairly even round hole.

Next, the heated end of the second tube is connected to the opening of the first tube. When soldering glass tubes together, to level the seam zone, it is necessary to blow air into the end of one or two tubes.

Glass bowl

How to blow a glass ball ?! To make a glass ball, use a glass tube. Before starting, it is necessary to melt one end of this tube (the method of riveting is indicated above). It will greatly heat the tube, placing it in an upright position so that the liquid glass gradually flows down and accumulates at the fused end. You must not forget to rotate the tube so that the walls are uniform in thickness and warm up well.

When a sufficient amount of glass has accumulated at the bottom of the tube, we remove the tube from the flame and, without stopping the rotation, we begin to slightly blow air into it.
