4 small problems in the house that can be fixed with ordinary chalk

Geophagy - trend or tradition?

Among ASMR fans, YouTube channels where people gnaw on chalk have been popular for a long time. And while some enjoy the crunch from the speakers, others, on the other side of the monitor, enjoy the process of eating limestone. Today, such videos collect hundreds of thousands of views, and followers appear among the viewers. You can see this for yourself - just search for entries using the hashtag #chalk or #chalk. The search will give you an infinite number of videos.

Often in society, melody is considered something wild. Many in childhood had a strange acquaintance who stole school crayons and ate them while no one was looking. The teachers cursed when they noticed such things, not understanding the unusual habit. But everything has its own rationale.

Many doctors explain that the desire to try chalk may be dictated by a health condition: a lack of calcium, iron, or thyroid disease. Therefore, experts advise to go to the hospital and get tested before eating chalk. At the same time, sometimes even completely healthy people have an unnatural desire to eat a crumbly and crispy piece of lime. This is not dictated by any physiological reasons, and scientists cannot logically justify the desire to eat chalk in people who are not deficient in micronutrients.

By the way, eating chalk, earth or clay has a scientific name - geophagy. It was widespread in pre-industrial society and was not considered something unnatural. Ampo, a soil dish, is still popular among tribal Indonesians to this day. Geophagia is also often seen among pregnant women – many of them are often deficient in the micronutrients they get from tasting chalk.

Production

How are crayons made? In Belgorod, chalk was made before and is now created by the extrusion method. In this case, the wet mineral in the form of thin sausages comes from a device similar to a meat grinder. The sausage is placed on a baking sheet, cut and dried in ovens. The result is round crayons. The technological originality of this product is that its “binding” is carried out by glue (most often PVA), which is not entirely safe for the health of babies (it is known that children eat white chalk, however, like adults). But she almost does not get her hands dirty, soft, pleasant to the touch.

Chalk has been used for drawing for a long time. Archaeologists are still discovering cave drawings made by this breed. Some artists drew sketches of their paintings.It was then that chalk, for convenience, acquired its generally accepted form in the form of a stick.

Since chalk is a loose and soft rock (powder), it is often mixed with binding substances - water and clay. After the resulting mass is placed in molds and dried. If a colored material is needed, a variety of impurities are added to the mixture. For black crayons, for example, carbon is added, and for bright red crayons, iron oxide is added.

Some manufacturers add dextrin or gypsum as a binder. And from this mixture, school chalk is further made. To obtain colored crayons, dyes are sometimes added at the last stage.

Other Uses for Chalk

A box with school attributes should be at hand all the time. You can use it very often.

Help a woman

• Very often, chalk is used when cutting fabric. It is desirable to make thin lines so that the markup can be easily removed.
• It's great for cleaning silver jewelry. Very often, this metal tarnishes and darkens during long-term storage, so you have to give the products to the workshop. Ordinary school supplies can avoid unnecessary expenses.

Before wearing, you can simply rinse or wipe the jewelry with a soft cloth to restore a delicate shine.

• School chalk is also useful for all other metals subject to darkening. You just need to put a piece in a jewelry box, and the jewelry will have a beautiful appearance for a long time. Items will not darken or change color.
• Some housewives go further and put the bar in a box of rarely used cutlery. Thanks to this simple action, forks, knives and spoons look beautiful and elegant without much effort, even if they are only available for the New Year holidays.
• It is possible to restore the shine of door handles made of metal or brass. Moreover, such work will not require special efforts. You just need to crumble a piece, apply the resulting dust to a rag and wipe all the dirt. The item will quickly restore its former attractiveness.
• The chalk will successfully block the way for the ants. These insects cannot stand such paths. Either their ability to communicate with each other is impaired, or for some other reason, but the ants try not to cross them. So you can safely draw lines on the ground, enclosing a picnic area, or near doorways and window sills, protecting your home from unwanted invasion.
• Chalk copes with the smell of mustiness. Therefore, very often its bars are placed in shoe or clothing cabinets.

• Similarly, the smell in the basket with dirty laundry, which is waiting for its turn to be washed, is eliminated.
• It also makes your nails whiter. To do this, it is applied to an old toothbrush and the nails are treated from the inside, under the tips of the nails.

Useful for a man

• A diligent owner often leaves a piece of chalk in the toolbox. This helps protect them from moisture and rust. Especially if the tools are stored somewhere in a garage or unheated room. Yes, and in the summer, such a procedure will not be superfluous.
• Use a white block to perfectly sand almost any surface.
• If the screwdriver scrolls or slips, the same piece of chalk can help. It is enough just to apply a little bit on the tool, and the problem of non-screwing screws can be considered solved. In the same way, you can rub the head of the screw.
• You can use the student attribute when repairing locks. You just need to rub the jamming key with a piece of chalk and insert and remove it from the lock several times to lubricate the entire mechanism. And you don’t have to buy expensive WD-40, especially since school supplies have practically no expiration date.

Why do you want to eat chalk?

The main reasons for which one wants to eat crayon:

1. Anemia. An insufficient amount of iron in the body leads to this very insidious disease. The level of hemoglobin decreases, the person becomes lethargic, pale, cracks appear on the skin, mucous membranes constantly dry, he does not want to eat. A person with anemia often feels tired and irritable, he does not want to do anything. Even with small loads, a person has an increased heartbeat.To find out why you really want to eat chalk, you need to see a doctor who will prescribe a general or detailed blood test. Anemia is more common in women, especially pregnant women. In severe cases, it can cause miscarriage or the birth of a sick child.
2. Lack of calcium in the body. It can not be absorbed in the body for two reasons: with severe liver pathologies and with insufficient intake of vitamins C, D, E. Lack of Ca in the human body causes brittle hair, delamination of the nail plates, tooth decay, and frequent convulsions. When a woman or a man wants chalk, it is difficult to determine on their own what is missing in the body. You should not self-medicate without knowing what caused the appearance of certain symptoms.
3. Diseases of the thyroid gland. Some endocrine disorders provoke a very rapid excretion of calcium from the body, so a person wants to replenish it and begins to eat a natural mineral. This cause is eliminated after treatment of the thyroid gland.
4. Pregnancy. What to do if a woman in an “interesting” position wants chalk? First you need to consult a doctor. The reason may be a lack of calcium in a woman's body or a simple change in taste preferences. If you really want to, you can eat 1-3 small pieces, the main thing is that the chalk is food, not technical.
5. Psychological addiction. A person with psychological problems sometimes wants to chew on something. This calms him down. Such a person can eat even one kilogram a day, which causes various diseases. It is recommended to eat pumpkin seeds or sunflower seeds instead of chalk, nut mixes, fruits. You can try to relax.If the addiction cannot be overcome, you need to contact a psychologist to eliminate the causes of addiction.

These are the main reasons why a person really wants to eat chalk. But it can be replaced by products, vitamin complexes.

Pregnancy and chalk

Many women, when carrying a child, eat chalk in incredibly large quantities. This is caused by anemia, or low calcium in the diet.

Is it possible to eat chalk during pregnancy, the composition of which is intended for whitewashing?

In no case. There is an accumulation of harmful chemical components: gypsum, lime, adhesive binder. The body of the expectant mother is poisoned, and the baby also receives toxins. This leads to the development of many diseases. The intestines, liver, blood vessels, respiratory tract are exposed to danger.

Can pregnant women eat the chalk used at school?

For the same reason, a chemical composition harmful to the body is impossible. The desire to eat a piece will disappear immediately if you fill the diet with healthy food enriched with natural mineral and vitamin complexes.

Harm to children

Can children eat school chalk?

If you meet a child chewing crayon, stop this outrage immediately. Such chalk is not absorbed by the body at all, and is very toxic for a growing organism.

In addition to slagging cells, it adversely affects the condition of delicate gums, weak milk teeth: solid particles scratch the mucous membranes and enamel, lead to the development of caries, stomatitis, and other diseases of the oral cavity.

Chalk dries the epithelium of the larynx, respiratory and digestive organs, promotes the formation of microcracks, where favorable conditions are created for the habitat and reproduction of pathogenic microorganisms.Therefore, to the question: “Is it harmful to eat chalk,” there is only one answer - it is very harmful, especially for children.

Harmful properties of the product

Food (pharmaceutical) chalk is undoubtedly rich in calcium and some other minerals that have a beneficial effect on human health. Moderate consumption of this product helps to form the skeleton of the child, strengthen the bone tissue of the elderly.

At the same time, chalk can be useful (in crushed form) for the health of teeth, nail plates and hair. However, this product can cause harm to the body. Negative consequences can be expressed in the following:

• Natural calcium, which enters the body from natural material, is difficult to digest. Sedimentary rock does not completely dissolve in water. In the same way, it behaves inside a person. This property is a prerequisite for the formation of sandy deposits and stones in the kidneys.
• The most complete assimilation of the product occurs only if it is consumed together with vitamin C or juices with a high content of this vitamin.
• For ingestion, it is allowed to use only specially made food chalk. All other types of this product are unsuitable for food. This category includes fodder chalk (for animals), construction and school. Various additives used for the manufacture of these species are not included in the category of edible.
• Excessive consumption of the mineral can lead to a disorder of the internal organs. In addition, the dry product is deposited on the mucous membrane of the respiratory tract. There is a risk of damage to tooth enamel, leading to subsequent dental disease.

The lack of minerals in the body can be established by analysis.Only the attending physician has the right to decide whether the patient needs a natural component or whether it needs to be replaced with medicines suitable for treatment.

Food chalk: application

Most meloids cannot live without their favorite treat and day. Each of them has its own "dose". How much can you use chalk, so as not to harm the body? Experts recommend not to get involved in eating this substance.

For some people, food chalk helps to cope with the increased acidity of the stomach. To do this, it is ground into powder and consumed one teaspoon per day. Some pharmaceutical preparations designed to lower the level acidity of gastric juicecontain calcium carbonate. The substance has antacid properties and can be used for peptic ulcer disease.

How is chalk made? It is mainly obtained by open pit mining. The mined blocks are crushed, then immersed in water. With constant stirring, particles of calcium float to the surface. They are dried and used for a variety of purposes. By the way, it is unreasonable to use chalk in the form of masonry raw materials, since it has a low hardness.

Today, chalk is added to various cement mixtures in order to give them additional softness. Also, the mineral is in demand when creating glass, plastics, rubber, rubber, mixtures of composite and paintwork materials.

In huge quantities, the breed is used in the carpet and linoleum industry. With its help, they regulate the viscous qualities of latex glue, improve the heat-saving properties of products, and give them strength.

Calcium is necessary for the manufacture of soil fertilizers and animal feed. Chalk powder is the base for creating many cosmetic products: lipstick, powder, creams. It is difficult to imagine the functioning of the paper and cardboard industry without this material.

Doctors' opinion

Even if you have a lack of vitamins in your body, which you are trying to make up for by eating chalk, this can lead to a serious deterioration in health. Chalk can cause problems with the gastrointestinal tract, settle in the lungs and other organs, and also lead to diabetes. Another serious disadvantage is that it is impossible to find completely purified chalk. This means that metals are deposited in the human body, leading to negative consequences. Eating chalk is also caused by a psychological factor, for example, when you secretly try to eat this “delicacy” as a child. Pleasure in this case is caused not only by eating chalk, but also by the anticipation of this action.

Geophagy is observed in people with serious mental disorders, such as schizophrenia. But do not worry ahead of time, because eating chalk is only a minor syndrome.

Do not neglect your health and eat stationery chalk, because it contains glue and gypsum, which will certainly lead to poor health. For those who so badly want to taste chalk, doctors advise simply to undergo an examination in the hospital and identify the missing vitamins, and then drink a complex of vitamin supplements from a pharmacy. In addition, in the pharmacy you can find drugs that are in no way inferior to chalk in their taste.

Various mental disorders often occur against the background of negative thoughts and emotions accumulated over a long time.Of course, the best option would be to see a doctor. But you can try to help yourself. For example, take the Wikium course “Brain Detoxification”.

Anti-corrosion primer - salvation for the blackboard. — Blogs

All of us once studied at school and never, as children, thought about the conveniences that were provided to us. But years passed, and my daughter went to school. And us parents had to repair the classroom. We wanted to create good conditions for comfortable education of our children. Unfortunately, the state has stopped thinking about it, putting it on the shoulders of teachers and parents. We easily coped with wallpapering, painting windows, desks and chairs.

But the state of the board led us into confusion. She was no longer able to serve either the children or the teachers. Even sitting on the first desk, one could only barely make out what was written there. The top painted layer of the wooden board has worn off, exposing the wood structure.

We asked ourselves how to cover the board so that we could still work productively on it. Enamel paints obviously did not suit us, since chalk does not write normally on them. We decided to use the anti-corrosion primer "Zebra" GF-021 red-brown.

True, many of the parents were skeptical about such a proposal, but we, taking full responsibility for ourselves, decided to take a chance by testing such a coating for the school board. First, we washed the board well, let it dry. They began to cover with a brush, but the brush left stripes, but the foam roller did the job 5 +. The primer "Zebra" does not have a pronounced unpleasant odor like paints. The surface is matte, not glossy like enamel paints.The primer laid down evenly and covered the board well, even one layer was enough for the board to get the look we needed. The board was ready for use the next day. But it had to be used in action.

Our joy knew no bounds when we ourselves tried how chalk now writes on our new board.

New because this is the impression that everyone who saw it and wrote on it had. Children during the year used a new beautiful, and most importantly, easy-to-read board. Now, at the school where my daughter studies, all the boards are brought into proper shape with the help of an anti-corrosion primer.

Who and how can eat chalk

It is difficult to unequivocally answer the question of whether they eat chalk. Of course, it does not apply to food, but in some cases it may be useful. Consider it all points for and against taking it, find out when and how to do it.

It is a white sedimentary rock formed from the fossilized remains of algae and animals that lived here thousands of years ago. It contains calcium with inclusions of magnesium, metal oxides, quartz grains.

Chalk is most often eaten to increase the amount of calcium in the body.

From birth, a person needs calcium, and chalk itself could serve as one of its sources. But various additives can be undesirable and even harmful to nutrition. There are several types of this substance, outwardly similar, but differing in chemical composition:

• Building. It contains the chemical additives necessary for the production of works that are harmful to health.
• Clerical. For strength, gypsum is added to it, and for color - pigments. It is not dangerous, but it is not intended for food.
• Stern.It is used to feed animals, it is not suitable for humans.
• Food. This product is maximally purified from impurities and can be used for food.
• Children's crayons. In their production, it is taken into account that the child pulls everything into his mouth and can bite off a piece, therefore the amount of additives is minimized.

It should be borne in mind that the calcium contained in the crayons is poorly absorbed by the body. Therefore, even choosing a species that is safe for the body, it is worth considering the advisability of eating it.

The desire to chew on a piece of chalk does not just arise. If the body lacks calcium, it looks for ways to solve this problem, causing the need to make up for this deficiency in any way. This need may arise in pregnant women and young children and is eliminated by taking a complex of vitamins.

Once in the stomach, calcium changes its properties. Under the action of gastric juice, it is oxidized and ceases to be chemically neutral. As a result, it irritates the mucous membrane without providing a therapeutic effect. Calcium does not linger in the body, so melody becomes meaningless. It does not help with heartburn, but it causes constipation, metabolic disorders.

Excessive melody can cause liming of blood vessels

The appearance of an irresistible desire to gnaw crayons can be a symptom of a dangerous disease. It is advisable to get tested and make sure that it is not caused by iron deficiency anemia. In this case, a course of treatment will be required.

Pure, free from impurities, chalk in small quantities is harmless, but it does not bring any benefit either. Better adjust your diet, eat more calcium-rich foods, buy calcium gluconate at the pharmacy.

Will chalk make up for the lack of calcium? limestone damage

Can chalk make up lack of calcium

present in the body? To answer this question, we turn to human physiology.

It has been proven that calcium carbonate, which is the main constituent of chalk, contains 40% elemental calcium. This is much more than in other mineral salts (citrate, gluconate, lactate, and others). However, the absorption of this form of calcium is rather low - only 17–22%. And this is subject to normal or increased acidity of gastric juice. If the acidity is lowered - and there are many such cases in medical practice - the degree of assimilation of the macronutrient is practically equal to zero. So eating chalk will not bring any benefit to the body, but it will add a lot of health problems.

One such problem is the formation of kidney stones. Calcium carbonate settles in the main organ of the excretory system and causes the formation of sand and the hardest kidney stones, which are difficult to dissolve - calcium oxalate.

In addition, the body spends a significant part of the hydrochloric acid of the stomach on the assimilation of a large amount of chalk, which protects the body from the penetration of harmful microorganisms with food. As a result, the barrier function of the gastrointestinal tract is weakened. A person is more likely to suffer from infectious diseases.

eating chalk

fraught with another serious danger - lead contamination of the body. American scientists studied natural calcium compounds and found high doses of heavy metal in them (6–25 micrograms per 800 mg of calcium). Getting rid of lead once ingested into the human body will be very difficult in the future.The metal affects the brain, kidneys, red blood cells. Lead is especially dangerous for children. Metal poisoning causes a decrease in their intellectual abilities (and hence academic performance), a change in behavior (unmotivated aggression is observed).

Is it possible to eat chalk during pregnancy?

During the period of bearing a baby, the female body experiences a huge load. Almost every pregnant woman suffers from a deficiency of trace elements and nutrients. Such a problem can be expressed in an irresistible desire to gnaw a piece of chalk. Pregnant women may also like the smell of soap, whitewash.

Experts say that in small amounts of chalk (food) during pregnancy, you can use the expectant mother.However, such a "delicacy" should be selected carefully. Drawing crayons contain various additives and are completely different in taste from the original. It is better not to eat them.

A piece of natural chalk for a pregnant woman will be a good source of calcium. Before using such an unusual product, it is recommended to consult a doctor. Perhaps the expectant mother will need to undergo an examination to find out the reason for such a desire.

Pros of whitewashing

Lime whitewashing still does not have an equivalent alternative for finishing garages, cellars and basements for storing food stocks. It not only gives these rooms a bright and tidy look, but also performs sanitary functions, preventing the appearance of mold in conditions of high humidity.

The bactericidal properties of this coating will not be redundant and on facades, in bathrooms, kitchens, pantries of a private house - wherever there is a risk of development of pathogenic microorganisms. Nothing prevents it from being used in living rooms, because in addition to its natural origin and the absence of harmful substances in the whitewash, it has other advantages:

• The vapor permeability of whitewash stabilizes air humidity by absorbing excess water vapor and releasing it into dry air.
• White or light pastel color, which can be given to the solution with the help of pigments, makes the room visually more spacious, cleaner, lighter. A smooth matte texture is great for decorating interiors in a variety of styles.
• Chalk or lime mortar is easy to prepare and easy to apply to any surface.
• It is hardly possible to find a less expensive way to refresh the walls.

Utility rooms can be transformed independently in a short time

In addition, whitewashing walls with lime can hide minor wall defects by filling in small cracks and potholes.

If we talk about the shortcomings, then there are more of them in chalk whitewash, which poorly resists high humidity - chalk actively accumulates water, swells and exfoliates from the base. Therefore it is not used for bathroom decoration and unheated spaces. The chalk surface leaves marks when touched.

But this type of coating, unlike lime, does not emit allergens at all and can be used in children's rooms and in rooms for people who are sensitive to such things.

silver tarnish remedy

It's amazing how useful a simple crayon is in everyday life. If you have silver items in your home, it will help prevent them from tarnishing. It is no secret that silverware or jewelry quickly lose their luster and darken. To preserve the beauty of things, you can put a piece of chalk in the box with them. You can also rub it with silverware. The principle of chalk is that it absorbs all the moisture. Silver remains dry and does not darken.

Before using jewelry or cutlery, it is enough to rinse them or shake off the dust. You will notice that things shine like new. There is no need to polish them.
