Probably every man has ever had to replace broken glass. Marking new glass is not difficult, but cutting it neatly is not so easy. Cutting glass at home requires the use of only high quality special tools.

Preparatory stage

To minimize the occurrence of difficulties, the glass should be washed well and dried completely. If the material is new, it is quite enough to wipe it with unnecessary newspapers. Old glass is washed, degreased with kerosene and dried.

In order for the glass to meet the required dimensions, it must be marked with an ordinary pencil. Cutting must be done in such a way as to minimize waste, so the long side of the glass is combined with the longer side of the future product.

Required Tools

Before you cut glass with a glass cutter, you need to decide what kind of tool you have. The fact is that there are two types of glass cutters, while the technology for their use is significantly different:

1. diamond glass cutter it is expensive, but it is able to cut glass 10 mm thick. With this tool, even complex designs with curved lines can be cut. The instrument is held like a regular writing pen at a slight angle (only more vertically). The cut line should be neat, thin and colorless.
2. Roller glass cutter cuts glass with a thickness of 1-4 mm. On sale there are models with 1,3 and 6 rollers. Recently, the roller glass cutter with oil has gained particular popularity, since it is the easiest to work with. The tool is held strictly perpendicular to the working surface, while the pressure is regulated by the index finger. Subject to all cutting technologies, the line will be white.

It is not difficult to choose a tool for cutting glass, the work process itself is more difficult, because for a good result you need to be as accurate and attentive as possible.

Glass is completely laid on the prepared work surface. For starters, you can practice on a small piece. Experts recommend placing a thick wooden ruler under the glass cutter before cutting, positioning it so that it is away from the drawn line. To prevent the ruler from slipping, put a few pieces of rubber under it.

When cutting, you need to apply the same force evenly and draw an accurate line immediately. Repeated attempts to draw a line in the same place will result in cracks. If the line does not work out, you need to retreat 1 mm from the place of the first attempt and try again. After cutting, the glass must be placed so that the cut line coincides with the edge of the work surface. The lower side of the glass, which is on weight, is gently tapped with a glass cutter and broken off, holding part of the sheet on the table. You can break the glass with your hands or with pliers (with pieces of hose put on the ends).

But if neither one nor the other tool was at hand, you can try to cut the glass with sharp sewing scissors. It's simple: you need to mark the material and create microcracks with scissors.

Types of glass and features of work

There are practically no problems with cutting ordinary glass. But with other types of glass, serious difficulties can arise.

1. Strained glass.

Cutting tempered glass is practically not feasible, since most often when trying to cut it simply breaks in random places. If the plans include interior items using tempered glass, it should be cut immediately before tempering. This means that such work should be entrusted only to professionals.

1. corrugated glass.

Patterned glass is often used for glazing doors or other interior items. The cutting process is no different from working with ordinary glass, only corrugated glass is best cut with a roller glass cutter exclusively on the smooth side.

From a glass sheet, you can get designs of various shapes, but for this you need to learn how to cut it. If you have a glass cutter, then this task can be easily handled. And if he is not? How to cut glass without a glass cutter? In fact, there are several ways to cut material using various devices, which will be discussed below.

Preparation for work

Before starting work, it is necessary to prepare the glass itself: rinse it with water, degrease it with gasoline. If it will be mounted in a frame, then you will have to adjust the product to the desired size. In this case, an additional 2 mm of material must be cut off on each side. This applies only to wooden frames, since they are able to contract and expand under atmospheric influences.

Before cutting glass, you need to prepare the space. To work with it, you will need a table or some kind of stand. This will make cutting easier and help break the product more evenly. If the craftsman has to cut the material for the first time, then he should practice on small pieces in order to understand the basic principles. Only then can you move on to cutting large sheets.

Glass cutter

Before using improvised tools, you need to understand how to cut glass with a glass cutter. The cutting element is placed perpendicular to the surface and strictly along the intended line. They lightly press the tool and gently begin to lead “towards themselves”. If everything is done according to the rules, then the sound of glass being cut will be heard and a thin white line will appear on the sheet. A creaking sound when cutting indicates that the tool is not tilted correctly, it is broken, or it is pressed too hard.

After cutting with a glass cutter, the glass is placed on the edge of the table (or stool) so that the resulting line extends slightly beyond its edge. With one hand you need to hold the sheet, and with the other put pressure on the hanging part (it should fall off). If it doesn’t work with your hands, then you can gently tap with a hammer along the cut line. If necessary, the process is repeated from the beginning.

We use scissors

Not very thick material can be cut with ordinary scissors. First you have to do the markup. How to cut glass in this way? You need to immerse it in warm water and cut into pieces of the required size. If nothing happened or the material began to crumble, then tempered glass came across (cutting features are indicated below). To cut a large piece, you will need a bath or a large basin of water.

The procedure is carried out as follows: the markup is carried out with the tip of scissors, after which an unnecessary element is broken off. This method is suitable for sheets up to 3 mm thick and allows you to cut shapes with straight contours. To facilitate work, a template is made of cardboard, which is glued to the workpiece with glue. You should be aware that the material will be more pliable under a large layer of water.

Twine, gasoline and a lighter

The method described below will tell you how to cut glass evenly if there is no glass cutter at hand. Everyone knows that the material is afraid of sudden temperature changes. This property can be used to cut it. For work you will need: a twine with a maximum thickness of 2 mm (cotton only), a lighter, gasoline (kerosene).

The glass sheet is laid on the table and a line is marked with a marker along which it needs to be cut. Measure and cut the string so that it covers the entire length of the cut. After that, it is poured with gasoline and applied to the line on the glass. The twine must be set on fire so that it catches fire along its entire length. When the thread goes out, it is poured with cold water. As a result, the glass will crack at the point of temperature difference. If the crack has not gone through the entire sheet, then you need to repeat the procedure and lightly tap on the cut line.

We work with a soldering iron

How to cut glass if you have a soldering iron at hand? The material is placed on a flat surface and with the help of a needle file, risks are made along the edges. A ruler is applied to it and touched with a soldering iron indented from it by 2-3 mm. You need to warm up each place so that the glass cracks. The soldering iron is passed along the entire cut - so it will turn out to be quite even.

They break the glass with special tongs or lay it on the edge of the table. The fracture will pass exactly along the furrow when sticking along the cut of adhesive tape or wet newspaper. If the product needs to be inserted into the frame, then you will have to cover the installation site with putty or rubber strips. It is applied to the frame and closed with glazing beads, under which a rubber seal is placed.

Charcoal pencil cutting

Below we will talk about how to properly cut glass with a charcoal pencil (you can do it yourself). It allows you to cut various shapes from the material. For the manufacture of the tool you will need: charcoal (linden, birch) and gum arabic. Coal is ground into powder, gum arabic is added to it and a kind of dough is kneaded. Round sticks are made from the mass, after which they are thoroughly dried.

Before cutting on the glass, markings are made and the edges are filed with a needle file. The pencil is set on fire on one side and led along the line. As a result, cracks are obtained, along which the product breaks easily.

Cutting different types of glass

When cutting ordinary glass, there should be no problems. Various tools will help to cope with this task: from scissors to special glass cutters. But how to cut off Below we will talk about this. At home, you can also cut organic and corrugated glass.

Corrugated products are in great demand because they are inserted into doors and various interior structures. This material is easy to cut (like ordinary glass), so you can use the above tools. It should be remembered that the cut must be made from the smooth side.

Making holes

Cutting a piece of glass cloth can be easily and simply with ordinary tools. And how to make a hole in it and what is needed for this? It is necessary to stock up on wet fine sand, lead (tin) and a container for its melting, acetone, and a template. The template is a stick with a cone-shaped end, the diameter of which must match the size of the future hole.

To get the job done, you need:

• lay the glass on a flat surface;
• degrease the incision site and sprinkle it with sand so that a hill 50 mm high is obtained;
• take a template and make a hole in it at the top of the slide;
• melt lead in aluminum or enameled dishes (can be heated with gas or a blowtorch);
• pour hot lead in a thin stream into a sandy funnel;
• wait 5-7 minutes and remove the sand around the hole;
• carefully check the cooling of the casting with your finger and remove it.

Under the casting there will be a not quite perfect hole. However, a handle, decorative elements, fasteners and other closing details can be easily inserted into the resulting design. Before cutting glass in this way, you need to practice on scraps of material so as not to ruin the whole canvas.

From the above, it can be seen that it is possible without special glass cutters. However, in the process of work, care must be taken and some rules must be observed so as not to damage the material and not accidentally get hurt.

Reading time ≈ 4 minutes

Knowing how to cut glass properly is of the type that can be very useful to know. If necessary, you will be able to replace or install glass or a small fragment yourself without the help of strangers, which, firstly, is pleasant, secondly, it is savings, since you can do without calling the master, and thirdly, such skills can come in handy many more times and to be able to cope with such situations means to be prepared for them. After all, you never know what day trouble will happen and when you will need knowledge on how to cut glass.

How to cut glass with a glass cutter?

To begin with, you should realize that working with any glass products is always associated with risk, so you need to prepare in advance by wearing special gloves and goggles. For this procedure, you will need the glass cutter itself, a little patience and a minimum of knowledge on how to cut glass with a glass cutter. If the glass needs to be simply cut (that is, cut off one of the edges), the task will be completely easy. Take a sheet of glass and clean it before cutting it (if the glass is new, just wipe it with paper, if it has already been used, wash, dry and repeat the operation as with new). Mark the place where the cut will take place (using a marker). Now it's time to decide on the type of tool.

There are three types of glass cutters:

1. Diamond glass cutter. It is the best option, however, before making a purchase, please note that the price for it is appropriate, and if cutting glass is just a one-time action, you should not buy it. At the tip of the glass cutter there is a diamond coating, which allows you to cut glass of almost any type and thickness. It is easy to use, the result is almost always excellent, and the service life is much longer than a conventional glass cutter.
2. Cobalt-tungsten glass cutter. The most common and popular. Gained popularity due to its low cost.
3. Oil glass cutter. In fact, it is an improved version of the cobalt-tungsten (roller) glass cutter. The difference is that the glass cutter is equipped with a small reservoir of oil that is fed to the tip, making the result more accurate and the process a little easier. Used for cutting thick glass.

When the choice is made, proceed to cutting the glass. In fact, the process is very easy and simple, and if you have at least a modicum of knowledge and skills, you can do it in a few seconds. The glass must be laid flat on a table or any similar object, and then simply go with the glass cutter along the line marked with the marker, pressing it slightly against the glass. If the glass is not cut, it's okay, just break it (the structure is already broken and this will not be a lot of work). If you need to cut multiple sides, just repeat the action. Well, that's all, and now you know how to cut glass with a glass cutter and, accordingly, are fully prepared for this. If you need more information on how to cut glass, the video posted on the page will help you understand this task in more detail.

How to cut tempered glass?

If you have heard that tempered glass can be cut, but you do not know how to cut tempered glass, you can not look for such information and immediately forget about this idea. Toughened glass cannot be cut. In fact, it is possible to cut, but in doing so, it loses all its properties and usually collapses even before the cutting is completed. The only way to get tempered glass of the size you need is to cut out regular glass and then temper it (you can use the services of specialists for this).

tempered glass

Waterjet cutting can cut any type of glass:

• reinforced glass
• mirror glass
• triplex (laminated glass)
• fire resistant glass
• borosilicate glass
• armored glass
• laminated glass
• float glass
• Patterned rolling glass

and many other types.

We are approached a lot for cutting already tempered glass, we want to upset such customers, such glass as tempered or still have stemalite (tempered glass with enamel applied) is not cut by any technology, including waterjet cutting. Initially, the product is made, all necessary cutouts are cut out by waterjet cutting, and only then the product is sent for hardening. If dimensional errors have been made and this can be corrected by trimming the increase in size, then in the case of tempering the glass only needs to be redone.

Strained glass- usually sheet glass obtained by heating to a tempering temperature (650-680 ° C) followed by rapid uniform cooling with cold air from both sides. As a result of such treatment, residual compressive stresses are formed in the surface layers of the glass, providing its increased mechanical strength, heat resistance, and safety in case of destruction. When broken, such glass breaks into many small fragments with blunt edges that are not capable of causing serious injury. This effect is proof of the high impact strength of this glass. Since the evenly distributed impact energy, over a relatively long time, forms very small microcracks in the glass, allowing small fragments to be obtained. Thus, tempered glass has three main useful properties, each of which has its own purpose in the industry.

The safety and mechanical strength of tempered glass is used in construction, glassware, psychiatry, shop windows, hockey rink fencing, furniture, automotive and railway industries. Such a property as heat resistance makes it possible to glaze buildings without the risk of thermal shock, especially for glass tinted in mass. The only weak point of such sheet glass is the vulnerability to impacts in the butt, since in this place the residual stresses can easily be released and break the glass as a whole. Although a similar effect is often used in design (example: three-layer countertops or doors with the effect of “broken glass”)

Tempered glass cannot be cut, drilled or otherwise machined.

In the automotive industry, tempered glass is used to make side or rear windows. The use of tempered glass as a windshield is strictly prohibited (small, though not sharp, fragments can damage the eyes of the driver or passengers). For the production of windshields, silicate glass triplex is used. Although tempered glass triplexes are much stronger, they have the disadvantage of rapid and complete loss of transparency from strong impacts, which, however, does not prevent their use in architecture. Tempered automotive glass is marked with the English word "Tempered" - "tempered glass" or the letter "T".

In the USSR it was known as "Stalinite" (in honor of Stalin).

Glass products have always been very popular: frescoes, dishes and many other things created from scraps of this material have always amazed people with their grace and smoothness of lines. Looking at this splendor, it seems that to create it you need to be a real professional with vast experience in working with glass and a lot of necessary tools, and a mere "mortal" would never master this complex science. In fact, not everything is as sad as it seems at first glance, and anyone can get knowledge on how to cut glass at home.

Glass preparation for cutting

A lot depends on this stage, and the preparation process itself depends on which glass you decide to use for cutting. New glass, purchased specifically for this purpose, is easy enough to wipe, and it is best to use an old newspaper for this (this will avoid streaks and settling of small fibers). With used material, you will have to work, spending much more effort. First, it must be thoroughly washed using special glass cleaners. Secondly, degrease with a cloth soaked, for example, in kerosene and, finally, dry in a closed room to avoid dust on the surface.

In addition, the preparation of glass implies its cutting. As you know, you are unlikely to achieve completely waste-free production when working with glass, especially if you are planning to get a product of not quite the correct geometric shape. However, an accurate calculation will reduce possible waste to a minimum. At this stage, a more rational solution would be to match the longer side of the glass with the long side of the blank. Please note that the resulting trimmings should not be thrown away, they can be used in the future to create new products.

What tools to use?

Many of us are accustomed to believing that it is possible to cut glass correctly and efficiently only with a glass cutter. But what if you need to cut off a piece of glass urgently, but this tool was not at hand? There is another unusual, but no less effective way that helped our great-grandfathers get out of this situation. Such a tool is ordinary scissors available to any owner. Let's consider each method in detail.

Option 1: glass cutter

The technology for cutting glass with a glass cutter is quite simple. To do this, you must comply with certain conditions and choose the right glass cutter. To date, the choice of this tool is quite wide, which allows you to turn work into pleasure.

• A diamond glass cutter that has stood the test of time and remains a leader in its field to this day. Glass cutters with a beveled cutting edge are suitable for home use. Such a tool is designed to cut glass up to ten kilometers and is suitable for any thickness of the material used. From time to time, such a glass cutter needs to be sharpened on a special bar.
• Roller. As the name implies, the cutting part of such a glass cutter is made in the form of a roller made of durable cobalt-tungsten alloy. The number of rollers can be from one to six.
• Oil. Such a tool works on the principle of a roller glass cutter, with the difference that a reservoir of oil is built into its handle, which is automatically fed to the roller. Suitable for cutting thick glass.

To learn how to choose a good glass cutter, watch the video:

So, having dealt with the glass cutter, place the glass on a flat surface. Mark up the glass and get to work. You can use a ruler to make things easier. It is worth considering the moment that the line must be drawn the first time, otherwise a second attempt will lead to cracking of the surface. To cut glass with a glass cutter, you need to apply the same effort along the entire length of the line being drawn.

Option 2: ordinary scissors

Cutting glass with scissors like paper is not a fairy tale, but quite an ordinary reality. For this purpose, you will need the scissors themselves (sewing is best for this) and a tank of water (preferably hot). It is necessary to mark the glass in advance, and then elementary physics comes into play: scissors create a microcrack, and the capillary effect completes the process. Of course, the result obtained will differ from that achieved with a glass cutter, but if necessary, this method can greatly help out.

Types of glass and features of work

Cutting ordinary glass does not cause almost any difficulties. Not only glass cutters, but also ordinary tailor's scissors do an excellent job with this task. But what about those who set themselves the task of obtaining a glass product with a more complex configuration. To do this, it is worth familiarizing yourself with the properties of some glasses.

• tempered glass products. In fact, it is impossible to cut tempered glass at home - it loses its properties. If you want to purchase an item with elements of this material, you should think about cutting it in the early stages. In addition, work with it should be carried out by professionals, since the process of hardening the resulting product can only be carried out under certain conditions.
• corrugated glass. This patterned glass is especially popular in glazing doors or creating decorative interior elements. Unlike tempered glass, such glass is quite capable of cutting on its own. Working with it differs little from working with ordinary glass, the only difference is that the cut is made from the smooth side. For this, a roller glass cutter is best suited.
• Acrylic or organic glass- This is a transparent plastic created on the basis of synthetic resins. No special tools are required to cut it. At home, a metal saw, cutter and other tools used for edge processing do an excellent job with this task. In addition, with glass, the thickness of which does not exceed 2 mm, an ordinary clerical knife does an excellent job.

In any case, it is worth remembering that working with any glass must be accompanied by certain precautions. The presence of tight gloves and goggles is the main condition for the implementation of their own safety. It will not be superfluous to take care of the arrangement of the workplace. Since working with glass involves the presence of fragments, cover the work surface with any material that you would not mind getting rid of. Feeling safe will allow you to achieve the best results.

For some reason, everyone writes about scissors as science fiction. About 25 years ago I read somewhere about this method ... and tried it - it was necessary to cut out the figured glass. In a basin of water, ordinary scissors, glass and go! - I didn't expect it to be so easy! Of course, it didn’t cut, but pieces broke off, but exactly in the right place! ..
