I accidentally noticed that I haven’t seen beautiful winter patterns on window glass for a long time. Previously, you look out the window in the morning, and everything is in patterns - that means it’s frosty outside. This year we installed plastic windows at home and now, despite the severe cold that has arrived, there is nothing on the windows. “And I became interested in why this was happening,” Nadezhda Zakharzhevskaya, a resident of Izhevsk, contacted the editor.
Answered by Vsevolod Plotnikov, designer of aluminum structures and PVC windows from one of the Izhevsk companies.
- The main reason is this: patterns on windows in frosty winter appear when water vapor from the air condenses on the surface of cold glass and then crystallizes, forming ice. In other words, the glass and the layer of adjacent air must be cold enough. Plastic windows have better thermal insulation properties than wooden windows, so the temperature of the glass on the inside is higher. Consequently, condensation and crystallization proceed worse. Simply put, old windows “breathe” and the cold enters the apartments, and patterns are formed due to temperature changes.
Old windows are double frames with single panes of glass inserted into them. The frames are not sealed, between them (and, therefore, between the glasses) there is ordinary room air, and all those processes of moisture condensation and crystallization take place on the cold glass. And double-glazed windows are inserted into plastic windows - two or three glasses, hermetically sealed. Between the glass panes of a double-glazed window there is not humid room air, but dry air, cleared of dust and moisture, and sometimes not air, but inert gas. So it turns out that there is nothing to condense on the coldest outer glass - there is no moisture in the glass unit chamber, and patterns cannot be obtained on the inner (room) glass, since it is too warm.
There is another reason: old wooden windows are usually “dirtier” than plastic ones, that is, there is more dust (even invisible) on the surface of such glass. But it is the dust particles that are the centers of condensation and crystallization of water.
But in very severe frosts, patterns can also form on plastic windows. This may also be because the windows are not installed quite correctly, are not sealed enough with a special rubber band, etc.
By the way, clients often ask companies that install PVC windows this question.

The symbol of winter in past centuries was not only severe frosts and snowdrifts, but also ice patterns on windows, which, according to ancient belief, are drawn by Santa Claus himself. Ice crystals form unique pictures on the glass, in which you can see the forest thicket, unusual animals, fabulous trees and flowers, the sea, and stars. In order for ice gardens to bloom on the windows, it is necessary that the air in the room be humid and the temperature outside the window be below zero.
Why do frosty patterns appear on the window?
Everyone remembers the parable that Santa Claus draws frosty patterns on the window. He quietly creeps up to the window at night and paints unique frosty pictures on it with a thin icy brush. In fact, everything is much more prosaic. If the air in the room is humid, and the temperature outside is zero degrees Celsius or lower, then excess moisture condenses on the cold surface of the window glass. Here the water vapor cools and changes from a vapor to a solid state, forming thin crystals.
Anything that looks perfect has microscopic nicks and scratches. The moisture that settles on the surface of the glass crystallizes first of all on these tiny defects, and only then more and more cling to the first crystals, forming patterns. Sometimes, for the appearance of icy patterns, all it takes is dust particles that litter the surface of the glass, or stains that remain after washing the windows. Drafts and air currents also contribute to the appearance of patterns. According to the method of formation, frost patterns are divided into two types: dendrites - branchy patterns that resemble trees, and trichites, which are more like stars.
Why are there no patterns on plastic windows?
Patterns on windows in frosty winter appear when water vapor from the air condenses on the surface of cold glass and then crystallizes, forming ice. In other words, the glass and the layer of adjacent air must be cold enough. Plastic windows have better thermal insulation properties than wooden windows, so the temperature of the glass on the inside is higher. Consequently, condensation and crystallization proceed worse. Simply put, old wooden windows “breathe” and the cold enters the apartments, and patterns are formed from the temperature difference.
Old wooden windows are double frames with single panes of glass inserted into them without double-glazed windows. The frames are not sealed, between them (and therefore between the glasses) there is ordinary room air, and on the cold glass the processes of moisture condensation and crystallization take place. And in PVC windows they use two or three glasses, hermetically sealed. Between the glass panes of the double-glazed window is not humid room air, but dry, free of dust and moisture, or inert gas. So it turns out that there is nothing to condense on the coldest outer glass - there is no moisture in the glass unit chamber, and patterns do not form on the inner glass, since it is too warm.
There is another reason: old wooden windows are usually “dirtier” than PVC windows, that is, there is more dust on the surface of such glass, and water crystallizes on the dust particles.

Chaotic lines, wide stripes and arcs, the smallest woody motifs... The main artist in winter is frost, which paints unique pictures on the windows. How does this happen?
In scientific terms, frosting occurs on the inner surface of the glass. The fact is that the air temperature near windows in the winter season is always lower than in the rest of the room. Cold air cannot contain as much moisture as warm air; it falls in the form of frost in winter or dew in summer. If the glass temperature is above zero, then the windows become covered with tiny droplets of moisture - they fog up (those who wear glasses will understand what we are talking about). And if it is below zero, then water vapor settles not in the form of water droplets, but immediately in the form of ice crystals (that is, water transitions from a gaseous state immediately to a solid state - sublimation). Such ice crystals (frost) cover the glass with a thin layer.
And the pattern is associated with air movements in the room: people move, the hood is working, windows are opened for ventilation, there are cracks in the frames, etc. The features of the glass surface (tiny scratches, dust or fingerprints, etc.) play an important role. The combination of these factors forms a unique frosty pattern.
By the way, not only windows can become frosty, but also any objects cooled to a negative temperature that are brought from the street into a warm room. It’s just that the frost on them doesn’t look so impressive, and these objects usually quickly heat up to room temperature. Another thing is windows, the low temperature of which is maintained by external cold.
And most importantly, the pattern on the windows also indicates that the room has poor thermal insulation. In modern double-glazed windows, where two or even three glasses are used, frosty patterns no longer form. In this case, there is a vacuum with zero moisture content between the glasses and there is simply nothing to settle on the cold glass (the one adjacent to the street). Now the lot of frosty patterns are houses in villages, windows of some buses and trolleybuses. Progress leaves romance in the past...
Tropical summer landscape Draws a cold on the window Why does it need roses? Apparently this is Winter yearning for spring. (D. Kedrin)
Project topic: “Why do frosty patterns appear on windows in winter?”
Purpose of the study: to find out why bizarre frosty patterns often appear on windows in winter.
Objectives: study the literature and select interesting information about how frosty patterns appear on windows; find out why frost patterns come in different shapes; observe the appearance and disappearance of frosty patterns on the windows; draw conclusions and summarize the results of observations.
Hypothesis: Suppose that the shape of snow patterns can predict the weather.
How do snow patterns appear on windows?
In winter, the air near the window glass becomes very cold and some of the water vapor from it settles on the cold glass in the form of ice crystals. Then these crystals begin to branch and grow, “drawing” snow (frost) patterns on the glass.
In order for crystallization to begin, the first ice crystals need to settle on something. Let it be a speck of dust. Or a trace from a rag used to wipe the windows.

Do frosty patterns appear on all windows?
Patterns do not appear on the window if the window is open. Frosty patterns cannot appear on a double-glazed window Previously, when the stove was stopped in the evening, the glass temperature dropped below 2 degrees. Droplets of water froze on it.
What types of frosty patterns are there?
Dendrites (tree-like formations). Dendrides are formed if the air humidity is increased, and the cooling of the glass began at a positive temperature and continued with a further decrease in temperature.
Dendrites on the mirror of our car
Trichites (fibrous forms). Trichitis occurs on glass precisely when there are a lot of scratches, nicks and dust particles.

When do marvelous pictures of ice crystals form?
When there is a sudden cold snap, the temperature of the windows becomes lower than the air temperature in the room. Warm water vapor in the humid air in the room settles on them. A thin, almost invisible layer of water appears on the glass.
Folk signs: if the branches of the patterns were directed downward, the weather will be snowy and cloudy; if up - clear and sunny. straight patterns foreshadow even greater cold, oblique ones - thaws, and more intricate patterns - snowfall.
Analysis of observations and conclusions The goal that I set for myself has been achieved. I found out why bizarre ice patterns often appear on windows in winter. I made the following conclusions: Frosty patterns on glass are large ice crystals growing from water vapor at the border of heat and cold; The type of pattern on the surface of the glass depends on the temperature inside and outside the room, the humidity in the room, the thickness of the glass and how dirty its surface is.
Analysis of observations and conclusions With high-quality glass sealing, patterns do not appear on the glass, because no temperature difference. Frosty patterns do not form on modern windows (double glazed windows). My observations support the hypothesis that the shape of snow patterns can predict the weather.

Thank you for your attention!
People of the older generation remember very well what magnificent patterns formed on the windows during severe frosts. And this beauty appeared in winter, in almost every home. This phenomenon has always amazed us, and at the same time raised the question - who creates such beauty?
No matter how beautiful these window patterns were, in most cases they have disappeared from our reality. And the point is not even that most of us have plastic windows on which frost does not freeze. Even on classic wooden windows, now more often just a flat white field is formed, with some touches. And only in very few places can you still see these fantastic pictures in winter.
In fact: why did the frosty patterns on the windows practically disappear? In order to answer this question, it is necessary to know the properties of human nature. It turns out that human energy is formed by the soul. And as it has now become known, this energy is capable of going beyond the body and influencing external substances and objects. Human thought can have a particularly strong impact on water.
One Japanese researcher carried out experiments confirming this position. As a result of his research, he found out in particular that depending on the quality of thought, crystals of the appropriate quality are formed. That is: positive thoughts form beautiful crystals - and negative thoughts form ugly crystals. To do this, it is enough for a person to generate negative energy.
How can this information be connected with the phenomenon that we are talking about here? And for this we must again turn to human nature. We have found out that the human body works from the energy of the soul. And, of course, the main potential of this energy is activated during the day. Most of this potential goes not only to the work of the body’s muscles and accelerated biological processes, but also to thoughts. At night, much less energy of the soul is spent on these processes. This means that some energy potential remains unused. And since the human soul is designed for constant dynamics without rest, its potential, freed from bodily needs, tries to manipulate external elements. And water molecules that condense and freeze on window glass are quite suitable material for such manipulations. And the souls of people expressed their beauty on the glass windows.
It was like that before. Nowadays, souls rarely allow themselves to engage in “window creativity.” Will a person paint if he has more pressing matters to attend to? Obviously not. What kind of affairs have appeared in human souls?
As you know, the soul, being in the body, is obliged to take care of its biology. One of the most necessary tasks for it is to ensure the energetic purity of the body. However, rarely do any modern people maintain such purity inside.
Any negative human reaction - be it envy, anger, or immoderation in one's desires - all this literally poisons our bodies. The research conducted by the Japanese scientist fully proves this position. By the way: in an experiment on the influence of thought energy on rice and water, it was found that the positive energy of thought turns this mass into kvass. From the perspective of human perception, kvass is a useful education. But the negative energy of thought caused the rice to become moldy. From a human perspective, this is already “poison”.
It's no secret that the modern world stimulates our negative reactions. All this poisons our biology. “The Creator's Mosaic” describes a technology that allows one to cleanse the body of the “dirt” that a person has accumulated during the day. And since few people know about this technology, we do not try to cleanse ourselves, and with such “poisoning” we calmly go to bed. As we have already said: a person who likes to draw will not sit down for this activity if the house is dirty.
Remember how a negative thought poisoned the water with rice, causing this mass to become moldy. The same thing happens with the biology of the body; if a person produces many negative reactions during the day, the body will be poisoned. Accordingly: the liberated potential of the soul will not even try to draw window patterns - it will strive to get rid of the “dirt” that a person formed during the day.
Now we know why the frosty patterns on the windows disappeared in most families. It's all about creating more negative reactions in people. And we are stimulated to this not only by society, but also by watching films and programs that carry negativity.
In order to not clog your body, you need to not only learn to filter screen dirt, but also learn how to properly respond to external negativity. The instructions for life set out in the texts of “The Creator's Mosaic” are ideal for such lessons. Bring joy to your soul - study these materials thoroughly! And besides, this will bring great joy to your body - you will no longer get sick. Probably after this your soul will be able to draw beautiful pictures on the windows at night. Good luck!
