People come into contact with glass products every day. Glass is an almost magical object - transparent on one side, and a material object on the other. A substance will be transparent when photons (light quanta) pass through it without being absorbed. But for some reason, not everyone comes up with the idea - how and what is glass made from? How does the process work?
Interesting facts:
- It will take a million years for glass to decompose.
- Glass is recycled without loss of quality.
- The thickest glass in the world is the 26 cm screen of the Sydney Aquarium.
What is glass made from?
To make glass, craftsmen take: quartz sand (the main component); lime; soda;
First, quartz sand, soda and lime are heated in a special furnace to a temperature of 1700 degrees above zero. The grains of sand connect with each other, then homogenize (turn into a homogeneous substance), and the gas is removed. The mass is “dipped” into molten tin at temperatures above 1000 degrees, which floats on the surface due to its lower density. The smaller the mass that goes into the tin bath, the thinner the glass that comes out.
Interesting facts:
- Murano glass is considered the most expensive in the world. Products made from it cost millions of dollars. Since ancient times, Venice has been famous for the production of high-quality glass. It is reliably known that in the 13th century the state government moved production to the large island of Murano, and the craftsmen were strictly forbidden to leave it. The punishment is a death sentence. In addition, entry to the island was also closed to tourists or other residents of Venice. Such strict measures made it possible to maintain the secret of production.
- One of the most interesting mental illnesses of the Middle Ages is the “glass disease.” A person with such a disorder thought that he was made of glass and was afraid of breaking. The French king Charles VI suffered from this disease. The monarch always wore several layers of clothing and forbade anyone to touch himself.
What functions do soda and lime perform in the production process?
Baking soda helps reduce the melting point by 2 times. If you do not add it, it will be very difficult to melt the sand, and, accordingly, to connect individual grains of sand with each other. Lime is needed so that the mass can withstand water. If it were not in the composition, the window, for example, would dissolve immediately after the first rain, and the glass would burst after contact with water.

Interesting facts:
- China did not produce glass for more than 500 years, from the 14th to the 19th centuries. Now the state is one of the leaders in production and controls a third of the world glass market.
- 1994 was a very active year for glass recycling in the United States. If you put all the glass products recycled during that year in one line, you will get a kind of “road” to the Moon.
How is colored glass made?
Not only colorless glass is produced. To obtain a colored product, in addition to the main components, chemical compounds are added to the melting furnace:
- Iron oxides give glass a rich red tint.
- Nickel oxides – brown, purple (depending on quantity).
- To get a bright yellow tint, add uranium oxides to sand, soda and lime.
- Chrome makes glass green.
What characteristics and properties does glass have?
The proportions of components for the manufacture of glass goods are selected depending on their purpose. They are distinguished: household glass - that which is then used to make dishes, glasses, jewelry; construction – shop windows, windows, stained glass;
Experienced builders know how to make liquid glass at home. Liquid glass is presented in the form of an aqueous solution of sodium silicate, which is produced by firing the mixture. The last composition is made using soda and quartz sand. Liquid glass is quite easy to make, the main thing is to follow all the recommendations. The use of sodium liquid glass allows us to produce: Liquid glass is an excellent waterproofing material. This substance is indispensable in the chemical industry and construction (protection of foundations, floors, walls and ceilings from moisture). The use of liquid glass allows you to glue and connect various building materials, including the production of fire-resistant, acid-resistant and other masses. This glass is used to impregnate paper, cardboard, fabrics, and wood products (to give them greater fire resistance and density). Before applying it to any material, it is necessary to find out in what proportions the substance is diluted. It is also necessary to take into account the fact that liquid glass is used to make acid-resistant cement. Often, builders mix 1 part silicate glue with 1 part cement. The resulting composition is suitable for making fireproof masonry. To protect walls from moisture you will need cement mortar add silicate glue (maintaining a ratio of 8:1). The composition of liquid glass depends on the method of its production. The easiest way to obtain this material is to use a mixture of an alkali solution with siliceous raw materials. In this case, pressure and temperature indicators should be normal. The latter indicator is often equal to the value at which the alkaline solution boils. The consumption of this glass depends on the coating being processed. The drying period of liquid glass depends on whether it was used in its pure form or as part of a certain mixture. This indicator fluctuates within 10 minutes. – 12 hours The easiest way to produce liquid glass is to use a mixture of an alkali solution with siliceous raw materials. To make liquid glass at home, you will need the following materials and tools: autoclave; Initially, raw materials with silicon are processed in an autoclave. For this, a concentrated solution of sodium hydroxide is used. Another method for producing the material in question is to alloy soda with quartz sand. To obtain a detergent and cleaning agent at home, you will need to use liquid glass. Foundry production involves the use of the material in question in the form of a flotation reagent. Return to contents You can make various mixtures with your own hands, which include liquid glass. To obtain a primer, you will need to dilute the latter substance. For this you will need water and cement. For 10 kg of the second component, a similar amount of liquid glass will be consumed. Initially, the cement is mixed with the liquid. To do this, use a drill with an attachment or a mixer. The component in question is added to the resulting mixture. The composition is mixed. If the resulting primer hardens quickly, then water is added. Liquid glass can be used to treat wooden surfaces. At home, you can get a special waterproofing solution for wells. To do this you will need to sift the sand. The last bulk material, cement and liquid glass are mixed in equal proportions. The walls of the well are coated with the resulting composition. If necessary, the solution is applied 2 times. Fireproof mortar is used to construct the stove and fireplace. It can be easily obtained at home. Initially, a cement-sand mixture is prepared. Then liquid glass is added to it. It is not recommended to dilute such a solution in large quantities. This is due to its rapid hardening. To protect wood from mold and mildew, you can use a special antiseptic. To do this, you will need to dilute liquid glass with water in a 1:1 ratio. It is not recommended to apply such a mixture to concrete walls or surfaces plastered with cement-sand mortar. They are covered with a special sliding film. Therefore, subsequent puttying and painting is impossible. You can easily prepare impregnation for the surface of various materials with your own hands. For this, water and liquid glass are used. The second component dissolves in 1 liter of liquid. The resulting composition is applied to the surface with a brush several times. Each subsequent layer is applied after the previous impregnation has dried.
It should be noted that modern building materials do not provide for the use of liquid glass in its pure form. Typically, this material is used as a mixture designed to solve specific problems, including waterproofing, increasing strength, etc. So, can all glass be frosted? Almost everything, including painted and transparent cabinet glass, mirrors, furniture inserts, dishes, car glass, and crystal. The only thing that cannot be frosted is heat-resistant glass, which is indicated by a special sign. Aerosol and glass matting paste do not contain aggressive acids, but working with these chemical compounds It is necessary to do this in a ventilated area, wearing gloves and a respirator. The temperature of the room where the glass will be frosted should be from 18 to 30 degrees. The matting paste is also stored under the same temperature conditions. At lower rates, the composition begins to crystallize. If this happens, dip the tube of paste into heated water; this will not affect its quality in any way. Before you start, purchase: matting paste, alcohol, rubber gloves, a plastic or rubber spatula, a stencil for creating a design, aerosol glue, sponges and napkins. We prepare the work surface - degrease the glass with alcohol and wipe it with a microfiber cloth. If you are applying a design to glass, prepare a stencil in advance. You can purchase it in a store or make your own pattern using film as a base. Oracal. To prevent the stencil from moving while working, treat it with reverse side aerosol glue. It will fix the film well and will not leave marks; use masking tape if necessary. To be safe, place parchment paper on top of the stencil and smooth everything out again. Now let's move on to the matting itself. Apply the paste in a thick layer to the stencil and distribute it evenly over the entire surface, leaving it to soak in for 10–15 minutes. After this time, the glass will be etched and a design will be imprinted on it. We remove the top layer of paste and place it back into the container, and wash off any small residues with water, remove the stencil and wipe everything dry with microfiber. If you don't want to buy matting paste from the store, you can make your own. For the first option, take liquid glass and mix it with a small amount of distilled water and a pinch of tooth powder. To create a colorful design, add a dye such as red lead or ultramarine. For the second option, prepare 2 parts sodium or potassium fluoride, 1 part gelatin and mix them with 25 parts distilled water. Apply the resulting mass to the glass, and after it dries, pour 6% hydrochloric acid on top and leave it for chemical reaction for a minute. We work with gloves and with the window open. As a result of this interaction, hydrofluoric acid is formed, which will etch the glass. At the end, as with using store-bought paste, thoroughly rinse the glass with water. To apply matte patterns on small surfaces, such as a glass goblet, candlestick, flower vase, barn glass, you can use dry aerosols. They are sold in a large assortment different colors, giving you the opportunity to create a colorful matte pattern in a festive style. To process glass with your own hands using a matting aerosol, you will need an already familiar set of tools. First, we degrease the surface with alcohol, after which we apply a stencil, and seal all areas of the glass that you want to protect from paint with masking tape. Before starting work, shake the can and distribute it over the surface of the drawing. To ensure that the paint applies evenly, apply 2-3 matting layers, waiting for each of them to dry completely.. If this does not seem enough to you, then to consolidate the effect obtained, you can apply a matte aerosol varnish on top of the design. Its complete drying time is 1–2 hours. A sandblasting machine is used to impart a haze to glass in production. Now you can find similar devices for household use. Compared to matting pastes and aerosols, they have wider capabilities. Using sandblasting machines, you can create matting of varying depths and densities, and also use it to work with large surfaces. However, it will require some skill. But if you're willing to take the risk, then let's get started. Among the disadvantages this method I would like to note the reduction in glass thickness to 3 mm after processing. Therefore, glass with a thickness of at least 5 mm is suitable for working with a sandblasting machine. Are you tired of old glass surfaces? Do you want variety and don't know how to do it? There is a simple and effective way, which will help you deal with annoying glass surfaces. What is it? Is it really a banal replacement? Not really. There is a better and original option - to make frosted glass with your own hands. Such a transformation is completely justified and allows you to create an indescribable effect. However, the average person has a logical question: how to make frosted glass at home? You will learn the answer to this question from our article. You will see several matting methods, as well as surface care rules. What is so good about the frosted glass surface? This solution has its advantages: If you decide to experiment, then let's look at the available techniques for creating a mat on a glass surface. Matting methods are quite simple, so everyone can do it with their own hands. So what are these methods? Below is the list: This method can rightfully be called the most accessible and simple. There is a special matting film sold on the market that will help you when working with glass. You just need to stick it on the glass from the back side. It's all work. But there is one drawback - although the surface becomes opaque, it cannot be called a full-fledged mat. If you want to get a truly matte texture, then use the following options. This is no less complicated method. All you need is a glass matting paste, which is easy to buy in the store. It is produced by different companies. The glass matting process itself is very simple: That's all, now your glass has become truly frosted. We mentioned stencils above. This is a great opportunity to make an original gift for family or friends. The work is practically no different from the previous one. You can buy or make a stencil with the desired pattern on it. You can even order products with inscriptions and congratulations. Then all that remains is to carefully glue the stencil onto the glass surface and smooth it, starting from the center, moving towards the edges. If the design is small and the glass area is larger than the stencil, then cover the unprotected areas with masking tape so as not to mat the unnecessary surface. Then the process is identical: apply the paste, smooth it over the surface with a layer of 4 mm and wait 20-30 minutes. All that remains is to wash off the paste, rinse everything hot water and remove the stencil. The drawing is ready. You can find detailed instructions on matting with paste in this video: This is the method used in production. It is the most reliable and high quality. But it’s difficult to call it affordable. After all, sandblasting equipment costs a lot of money. If you have such a unit, then that's good. Some people rent it or look for people they know with such a device. A sandblasting machine can make matting of any depth and density. And for processing large surfaces it is simply irreplaceable. Advice! You shouldn’t immediately start trying to frost the glass on the work surface. It's better to practice on unnecessary glass. The disadvantage of this method is not only the mandatory presence of equipment, but also the fact that the glass after processing will lose about 3 mm in thickness. This is why it is recommended to use glass with a minimum thickness of 5 mm. In addition, you will need sand and a respirator for work. The process of creating a mat on glass is as follows: That's all, now you know how to make glass frosted. You can choose any option that suits your budget, strength and capabilities. A detailed instructions on matting with sandblasting you can find in this video: If making frosted glass is one thing, then caring for it is quite another. For example, many people do not know how to clean frosted glass from grease stains. After all, no matter how you look at it, this cannot be avoided. Even on the mat, dirt, stains and stains will be visible. What to do in this case? The first tip is to clean the glass surface immediately after dirt has formed. Then the stain will not be embedded in the material, and it will be quite easy to wash it off. You don't even need to use detergents or cleaning agents. It is enough to wipe the surface with a damp cloth or microfiber cloth. If you find serious contamination on the glass, you can wash it with special products, which you can buy in specialized stores or in a supermarket. However, you must remember one thing: the matte surface is afraid of cleaners that contain silicone or fluoride. To ensure that the matte surface always remains beautiful, you should take care of it from time to time. Natural suede will help you with this. It is enough to wipe the product with a piece of damp cloth. Another way is to wash the surface with hot water and vinegar. When you have processed the product, you should immediately dry it with a napkin. There is another popular way: Pay attention! Difficult stains and dirt can be removed with ammonia. Just when working, ventilate the room well or be outside. After all, everyone knows what a strong smell ammonia has. Such simple tips will help you properly care for your handmade product. As you can see, your old glass can be turned into an original product. Using matting, you can not only hide from prying eyes, but also create unique souvenirs for family and friends (cups, vases, beautiful bottles, mirrors). The matting process itself is simple and accessible to everyone. And if you properly care for such a matte finish, it will remain beautiful for many years to come. You can make simple glass original using several technologies. For example, make a stained glass window, create a drawing on it, or make a mosaic. But the most interesting way to make a truly designer product is to transform it into frosted glass. After matting, it turns into a material with a modified surface structure, becoming opaque. Several processing techniques can be used on one glass to produce original and truly individual products. Glass products– decorative lighting fixtures, souvenirs, vases, various dishes - these items are in great demand among the population. Often, we choose these items if we need to give a gift. We are attracted by matte sconces, salad bowls and glasses; they are decorated with various designs, patterns and natural ornaments. Undecorated products, although they cost much less, practically do not attract attention. You can matt both completely flat surfaces and things with complex shapes. There is no thing that would be impossible to decorate using matting. And their appearance limited solely by the richness of your imagination. When planning an office space, dividing walls with frosted glass will become indispensable. Often, matting is used in everyday life, making parts of glazed doors, edging mirrors, dishes and lighting fixtures. You can purchase ready-made frosted glass from glass workshops or make it yourself. The process is carried out in the following ways: The technology of mechanical processing (with special pastes) is quite simple. Using chemicals at home is risky. And the use of sandblasting requires special equipment and makes it possible to transform mainly thick glass, and processing using this method turns out to be rough. To install frosted glass in all-glass products, it is tempered. Knowing how to frost glass can also help the home craftsman. Often, kitchen cabinet doors are made using frosted glass. Restoring furniture is expensive, it will be cheaper and more convenient to make it yourself. Why are they good: The negative qualities of this material are considered to be slight roughness; dust collects on them. This flaw can be eliminated by coating the glass with a special varnish. Changing the structure of a glass surface using sandblasting– the most common matting technology. The flow of sand removes the top surface of ordinary glass, and it loses its transparency. By changing the fraction of abrasive material and the pressure in the unit, you can change the roughness and degree of dullness. There are several types of sandblasting glass: Glass etching to form an opaque glass surface is done using hydrofluoric acid. The matting paste covers the unprotected parts of the product through a stencil, and after a certain time it is removed and the glass surface is washed. Areas treated with paste become matte. Compared to sandblasting, sandblasting makes the surface less rough and does not require a protective coating after treatment. In production, the glass surface is completely treated with matting substances, thanks to which it is possible to create an ideal matte surface, which is called satinato. Film finishing- the most economical way. The glass is covered with a film with shading, patterns or designs. The disadvantage of this method of matting is the need to use the finished glass under special conditions - friction or heavy wetting of the surface should not be allowed. Lakomat– a special matting method. The surface is covered with a layer of matting varnish; it can be either translucent or white. When coating glass with varnish, the following tools are needed: This method requires special care and accuracy. Original products with an unusual effect are obtained by changing the glass surface using laser radiation. There is a method of processing glass using surface detonation and using metal spraying using a plasma installation; with this processing, small drops of molten metal heat the glass to a high temperature. As a result, microchips and very small cracks form on the surface of the glass. They create matte areas. But such matting technologies are practically not used due to the high price of equipment and the complexity of the manufacturing process. Types of glass that are used in the manufacture of frosted products:
There are several “recipes” for matting paste. Made using hydrofluoric acid or liquid glass. For hydrofluoric acid paste you need: Add the components in a ratio of 2:1:25 and mix well. Ready mixture Apply to the glass surface with a roller, after treatment they are washed off with clean water. After this, the glass is dried and kept in 6% hydrochloric acid for 60 seconds. Frosting of glass using this method is done using hydrofluoric acid. It cannot be used to form a pattern - the mixture will penetrate under the stencil. Liquid glass must be mixed with distilled water, after which a small amount of tooth powder is added to it, and the composition is mixed well. Pigments are sometimes added to the paste, for example, ultramarine or red lead. The washed glass surface is coated with paste using a roller, and after drying, washed with water. More intensely than on regular glass, any dirt is more noticeable on frosted glass, even fingerprints are clearly visible. Immediately after they appear, it is easier to remove them - you need to wipe the contaminated area of the surface with a slightly moistened microfiber cloth. Serious stains, such as those caused by grease, can be removed. Such glass must be occasionally wiped with a piece of natural suede and washed with heated water and a small amount of vinegar. After this treatment, the cleaned surface is dried using microfiber. Another option for cleaning a frosted glass surface can be treatment with a composition of several spoons of powdered chalk and 200 grams. clean water. The mixture is applied with a piece of rag to the glass surface, and when it dries, it is wiped off with newsprint. Heavy stains must be removed using ammonia, but it smells strong and unpleasant, for this reason, during such treatment it is necessary to intensively ventilate the room. Self-made frosted glass can become a true work of art, and with the help of timely care, the beauty of the product will last for a long time.Main characteristics and purpose
