School chalk buy wholesale and retail

Despite all the progress that has been made, schools still have blackboards on which they write with chalk. Once upon a time, ordinary natural chalk was used for this. It cost practically nothing, but caused a lot of inconvenience, since the chalk could be too hard or crumble, scratch the surface or leave a pale mark. School chalk, which can be purchased in any quantities from the TK Mel-torg company, is completely free of these shortcomings.

Features and benefits of school chalk

School chalk can be of natural origin (lumps or sawn) and industrially produced (pressed or sanded). The first type of product is cheaper, while the other is much more varied, since it can be given various special properties. The characteristics of school chalk of the second type are ensured by its production process, which includes the following stages:

grinding of raw materials;
sedimentation of heavy impurities (sand, etc.) in water;
preparation of plastic chalk mass by dehydration with the introduction of additives to impart special properties to the finished product;
molding crayons and their subsequent drying.

Clay, gypsum, casein and other ingredients are used as additives in the production of school crayons. The recipe for such products is not regulated by regulatory documents. The only requirement is harmlessness to humans. As a result, crayons can have different hardness (by analogy with graphite pencils), dusting is minimized. School crayons often have a square and round cross-section, less often - triangular and hexagonal. Colored crayons are made in the same way with the addition of dyes.

Typically, Antoshka chalk is produced in the form of bars with a square cross-section, up to 80 mm long, about 15 mm wide and weighing up to 30 grams. In general, its shape and weight are selected in such a way that it fits comfortably in the hand when working.

School chalk "Algem"

School chalk Belgorod (sawed)

School chalk is intended for applying information to the blackboard. Available in the form of round and rectangular bars. Packed in cardboard boxes. The number of crayons in the container may vary, but generally the package contains from 10 to 120 crayons. Colored crayons are offered in small quantities, since they are designed for elementary school students, but a large number of white crayons in a pack is due to the fact that white chalk is used by students of all grades and teachers.

Chalk is mined in environmentally friendly quarries in the Belgorod region at the largest deposit in Russia. There it is given the crayon shape that everyone knows from school.

Belgorod school chalk has medium density, does not get your hands dirty and does not crumble. It is also the most requested type of chalk in all schools in the country.

School chalk Orenburg (sawn)

Today, the market offers a lot of low-quality school chalk, so finding good chalk is quite difficult. Orenburg school chalk is exactly this type of chalk. It is soft, does not scratch the board, fits well on it and does not crumble much.

It is produced in the Urals in Orenburg from natural chalk. Has no additives or fillers. Supplied in the form of round bars, with a standard diameter of 8 mm and a length of 80 mm. Orenburg school chalks are snow-white and ideal for classic school boards.

5. Crayola wax crayons ("What is it made of")

Everyone has been familiar with white and colored crayons since childhood. The appearance in Russian schools of modern blackboards, on which you can write with special markers and felt-tip pens, has led to a sharp decrease in the production of school chalk. However, crayons manufacturers are trying to find new sales channels.

School chalk comes in two main types: lump and pressed. The natural chalk used to make school chalks is quarried or extracted from rocks. This raw material is absolutely safe, non-toxic and does not contain foreign impurities. The basis of pressed chalk is calcium sulfate, which is obtained from gypsum. Starch and limestone are used to make school chalk into specific shapes. Lump natural chalk consists almost entirely of calcium carbonate. For the production of school chalk, sorted natural chalk is used.

Colored crayons are produced using a similar technology, the only difference being that various dyes are added to the mass during the production process. The production of chalk for drawing and writing on boards and on asphalt includes several main stages: grinding the raw materials, settling heavy impurities, drying on a wire rack, adding an adhesive, and molding.

To make the highest quality crayons, exhausted chalk (or, as it is also called, melted) is used. To prepare elutriated chalk, natural chalk is broken into pieces, sorted, impurities are removed, and then ground with water on millstones. The resulting mass settles, as a result of which heavy impurities (sand, stones) are deposited at the bottom of the container. Then the liquid with purer raw materials is passed into the second and then into the third vat until all foreign impurities are at the bottom of the tank and are removed. The remaining chalk solution is left to settle for several hours, after which the water is drained, and the remaining mass is transferred to boxes with perforated walls, which are covered with cloth. Then the mass is dried on wire racks. If the chalk crumbles when dried, then add a small amount of dextrin solution or glue to it. Recently, so-called non-crumbling, dust-free crayons have become increasingly popular. They are made using special technology using casein. The main difference between these crayons and ordinary ones is that they do not stain your hands and clothes when used.

Colored crayons must also have a certain hardness. However, when dyes are added to the chalk mass after drying, the chalk becomes too crumbly. Therefore, when making colored chalk, chalk powder is mixed with a certain amount of mineral paints to obtain the desired shade and mixed in an aqueous solution of wood glue, gum arabic or dextrin. In principle, you can use any mineral paint, but keep in mind that some colors will be distorted when mixed with chalk (for example, cormorant, Prussian blue and chrome yellow). Colored crayons can be used not only for drawing on asphalt (in this case they must be very hard), but also for writing on a blackboard. To make the crayons more soft, add soap solution, oil or wax. Finished and dried crayons are dipped in oil, which improves their color and makes them more soft. A mixture of chalk, dye and binder is laid out on a flat surface, which is first covered with several sheets of paper. The paper absorbs a large amount of moisture, as a result of which the chalk mass acquires a thick consistency. When the mass becomes thick enough, a piece the size of a nut is taken from it, and then rolled into a cylinder. At the last stage of molding, the cylinder is rolled with a smooth board to give it a smooth surface. The finished crayons are laid out on boards, covered with paper and dried at room temperature.

This technology is considered quite expensive due to the large amount of manual labor. To reduce the cost of production, crayons are made from a mixture of light clay, water and chalk, to which a dye is then added - ultramarine (for blue crayons), mummy and cinnabar (for red ones), ocher (for yellow ones), etc. The whole mass is evenly mixed and transferred to special wooden or metal forms, pre-greased with fat. After molding, the pieces of chalk are removed from the molds and left to dry in the air or in a weakly heated room.

In addition, crayons can be made by grinding exhausted chalk with burnt gypsum (which does not set when wet) and soapstone. Then mineral paint is added to the mixture, and it is mixed with a weak solution of dextrin. The mass is placed on straining cloths to remove excess moisture. The dried mass is cut into prisms of the required size and left on gypsum plates to dry, turning them over to the other side from time to time.

The degree of drying of chalk and its composition determine the hardness of the product. Harder chalk is used for drawing on asphalt, medium-hard chalk is used for writing on blackboards, and soft chalk is used for tailoring work.

To produce white and colored crayons using these methods, complex, expensive equipment is not required. The total cost of purchasing everything necessary for production will be about 50 thousand rubles. In addition, you will need cardboard packaging for packaging ready-made crayons (white crayons are usually packaged in large boxes of 100 pieces, and colored crayons - in small boxes of 6-12 crayons). The total costs of organizing a small chalk production range from 100 thousand rubles (including the purchase of raw materials). Finished products are supplied to stationery stores, children's art supply stores, specialized stores for schools, as well as directly to public educational institutions.

Introduction

Each of us has a good idea of an ordinary, unremarkable school chalk. And not only does he imagine it, but he also held it in his hands more than once during his studies. And how many truths have been discovered with the help of a piece of chalk, how many discoveries have been made! And to this day, a school teacher, holding an inconspicuous, but at the same time irreplaceable piece of chalk in his hand, performs miracles. Is school chalk really so indispensable? More and more people have been talking and writing lately about the benefits of interactive whiteboards. But we still work with chalk at school. Yes, and we draw with chalk on the asphalt, fences, and on the walls of houses with chalk.

At school the teacher gives us chalk. At home, we ask our parents to buy chalk, but our parents won’t buy us chalk every day. And I was interested in the question: is it possible to make chalk yourself and from what?

Object of study: colored crayons.

Subject of study: chalk components: gypsum, starch, eggshells, glue, paints.

Hypothesis : There is an opinion that chalk can be made at home from improvised materials.

Target: make your own colored crayons at home

Tasks:

1) study the history of chalk;

2) learn about the technology of its production and the use of chalk in human life;

3) make colored chalk at home;

4) test the produced chalk on asphalt;

5) summarize the results of the work.

Research methods:

studying information;
practical (making chalk);
observation;
generalization.

Practical significanceis to describe different ways of making colored chalk at home. You can also invite your parents to save money on buying crayons.

What is chalk?

Chalk - these are the smallest remains of shells, fragments of the skeletons of extinct marine animals. Chalk was deposited in bodies of water over millions of years. And when they became shallow, the limestones came to the surface.

Chalk - sedimentary rock of white color, soft and crumbly, insoluble in water. Occasionally, mollusk shells, skeletons of bryozoans, sea urchins, lilies, flint sponges, and corals are found in the chalk.

Chalk is a semi-hardened marine silt deposited at depths of 30-500m or more.

Chalk belongs to very common substances of mineral origin in nature and is therefore generally known. It is also obtained artificially.

Natural chalk often has a grayish-yellow tint. There are also completely gray chalk. The best types of chalk (the purest) have an almost snow-white color, as they consist of almost pure calcium carbonate. By-product natural impurities found in chalk are: clay, quartz, magnesium carbonate, carbon and iron oxide. These impurities in good varieties of chalk do not exceed 4% of its composition. Carbon colors chalk gray, and iron oxide yellowish.

The artificial product is obtained by precipitation of lime solutions with carbon dioxide. This chalk consists of pure calcium carbonate, in which 100 wt. parts of the product account for 56 weight. parts of calcium oxide and 44 wt. including carbon dioxide. It has an immaculate white color, is extremely thin and covers well, but its price is significantly higher than the natural product.

3. Application of chalk

Chalk is used in agriculture (for liming soils, feeding animals). Precipitated chalk is used in medicine (as a medicinal preparation) and in perfumery (an integral part of tooth powders and pastes). In plastic art, chalk is used as a base for gesso and other primers, and as a component in the production of artistic paints (for example, pastels). White chalk and black chalk (so-called Italian pencil) are used as drawing materials. In industry, chalk is used for the production of cement and lime, as a filler for rubber, plastics, paints and varnishes, for the production of soda, glass, and sugar purification; making school crayons.

Technologies for making school crayons

There are several ways to make school crayons.

Extrusion method.With this method, wet chalk in the form of thin sausages comes from a machine similar to a meat grinder. The sausages are placed on a baking sheet, cut and dried in ovens. The resulting crayons are round in shape. The technological feature of these crayons is that they are “bonded” using glue (most often PVA), which is not entirely safe for the health of children (as you know, white chalk is literally eaten by both children and adults). But this chalk is soft, pleasant to the touch, and practically does not stain your hands.
Casting method . Cast white chalk is absolutely safe for health, since its binder is gypsum in very small quantities.

Cast chalk is made using a mold, which is a container with cells in the shape of an elongated cube. In the mixer, chalk powder is thoroughly mixed with gypsum (white chalk), as well as with dyes (colored). The quality of the chalk directly depends on the quality of the powder - it should not contain solid particles of gypsum or sand, which then scratch the board when writing.

The resulting powder is poured into a barrel, where it is manually diluted with water. The mixture is poured into the matrix and remains there for some time - the water gradually evaporates, and a binding reaction between the molecular structure of chalk and gypsum occurs.

Then the matrix is turned over onto a special lattice tray and “removed” from the crayons. After this, the matrices are washed in a special soap solution - damp crayons will be easier to come off. The pallet is placed in a drying cabinet, the chalk is kept there for a certain time, then the finished chalks are sent to the packaging workshop. Packaging is done by hand.

Exhaustion. For the best varieties of various crayons, the so-called exhausted chalk is used (in the trade it is called fused chalk). To prepare extracted chalk, natural chalk is used. It is broken into pieces, sorted, all impurities are discarded and then ground with water on millstones. The resulting mass settles, and heavy impurities (sand, stones) settle to the bottom. The liquid, containing purer material, is passed into the second vat, then into the third, until all foreign impurities settle to the bottom and are removed. Then the mass is allowed to settle in the vat for quite a long time, the water is drained, and the remaining mass is transferred to boxes with perforated walls, covered with linen. Next, the mass is dried on sieves, and if after drying the chalk is very crumbly, then add a little dextrin solution or glue.

Practical part. Making crayons

Making chalk is a simple and inexpensive endeavor that you can set up in your own home, using things you'll almost certainly have on hand. Add some color and you've got crayons you can draw with.

1 way

Gather everything you need.Besides the ingredients to make chalk, you also need to find a mold. Look around the house or head to your local hobby store to collect the following items:

Gypsum. You can buy a large pack of plaster of Paris at almost any hobby store. You will need 1/2 cup of gypsum per batch of chalk.
Gouache paint.
Wax paper (or wax the paper yourself with a candle). You need it to lay out the chalk molds for it. Without paper, the chalk will stick to them.
Something that you will use as a form. You can use cardboard toilet paper or paper towel tubes, plastic ice cube trays (unless you intend to use them for other purposes), or any tubes or cardboard molds.
Electrical tape or tape. You will need to close the bottom of the tube that you will use as a mold to hold the mixture inside.

Prepare the forms.Line pans with wax paper, glossy side up. If you are using tubes, tape one edge to keep the chalk mixture inside.

Pour the paint into a bowl.You need 2 tbsp. spoons of paint per batch of chalk. Measure paint into a bowl, one color per bowl. You can mix paints to create new colors; for example, mix red chalk with yellow to make orange, or blue with yellow to make green. Make sure the total amount of paint per bowl is about 2 tbsp. spoons

Add plaster. Sprinkle 1/2 cup plaster of Paris into each bowl. Stir the mixture thoroughly until all ingredients are completely combined and there are no lumps left.

Add a drop of liquid dish soap.This will make the chalk easier to clean. Simply stir 1-2 drops into each bowl of mixture.

Pour the chalk into the molds.Using a spoon, spoon the mixture into individual molds, one color per mold. Fill the molds as much as you like - the chalk mixture will not expand as it dries. Cover the pans with wax paper when finished.

Let the chalk dry.Transfer the chalk to a dry place to allow the moisture to evaporate. The chalk is ready for use after it is completely dry.

Method 2

1. Gather all ingredients.This method of making chalk includes only natural products that you can find in any store if you suddenly don’t have them on hand. Gather the following items in preparation for your chalk making project:

Egg shells.
Flour. It will thicken the mixture and make the chalk fluffier.
Food coloring. Both liquid dye and gel are suitable.
Forms. Use toilet paper tubes or ice cube trays, or any other shape you like.
Wax paper. You will need it to lay out the forms for it.
Duct tape.

2. Prepare the forms.Line your chosen pans with wax paper, glossy side up. If you are using cardboard tubes, tape one end closed.

3. Grind the eggshells.Make sure they are completely dry before doing this. Use a mortar and pestle or a bowl and the back of a spoon to grind the shells into a fine powder. Make sure that there are no large pieces of shell left; the mixture must be absolutely homogeneous.

1. Prepare the ingredients.A simple chalk recipe consists of two things: starch and water in equal proportions. Use food coloring to make more than one color. You can use toilet paper or paper towel tubes or other small containers as molds.

Products such as drawing crayons are familiar to everyone from early childhood. White crayons are always associated with studying, but colored ones are associated with children’s bright drawings on the asphalt. At the same time, both of them have not lost their relevance for many years, even due to the active development of all kinds of drawing products.

Of course, the appearance of whiteboard markers on the market sharply reduced business. But, nevertheless, this does not stop enterprises. They continue to operate as crayons remain in demand. Entrepreneurs are also trying to find new outlets for selling their products.

Growing your own business costs a small investment. To beat your competitors, you need to produce only high-quality crayons, and to attract attention to your own products, you should make bright boxes (possibly with images of famous cartoon characters).

Choosing a suitable room.

To produce crayons for drawing, you need to rent a production facility. There will be no special requirements for it, the main thing is that it is heated, a ventilation system, communications and an electrical line are installed. It is most profitable to rent premises in the city, with convenient access, but away from houses.

The room should be well lit. It is important that the floors have a coating that is easy to clean. Wet cleaning will need to be done regularly, as dust will settle in the air.

The size of the room can be 50 m2, everything will directly depend on the planned production volumes. The area will need to be roughly divided into production, warehouse and administrative premises. You must allocate at least $400 for renting the premises.

Special equipment.

The equipment for making crayons is quite simple and not too expensive. The line includes the following devices:

1. Machine for automatic liquid supply - from $1.2 thousand;
2. Mixer - $800;
3. Electric grouting machine - $3 thousand;
4. Slicing machine - from $1.8 thousand;
5. Packaging equipment - from $750 and above.

The total cost of such a production line from a Chinese manufacturer will be from 6 to 8 thousand $. White crayons are most often packaged separately in large cardboard boxes of 100 pieces. Colored crayons for drawing are packaged in quantities from 6 to 12 pieces.

Raw materials for making crayons.

The composition of crayons includes the following materials: a mixture of light clay, water and chalk. Such a composition is the most appropriate from an economic point of view, since such a complex of raw materials makes it possible to maintain the technology with a minimum amount of manual labor, which is reflected in the capital of the enterprise.

For coloring products, ultramarine is used to obtain blue-blue shades, mummy or cinnabar to give pink or red, ocher for orange or yellow, and others. Manufacturers often use other technologies. Then the raw materials are based on exhausted chalk with burnt gypsum, and mineral paint and a weak solution of dextrin are used as dyes.

In general, the choice of technology and components of crayons is a purely individual matter. To package crayons for drawing, you will need to purchase cardboard. But approximately $2 thousand must be prepared for the purchase of raw materials.

Workers at a crayons manufacturing plant.

There is no need to hire highly qualified personnel to work for a crayons manufacturing company. After all, the manufacturing technology is quite simple. Therefore, it is enough to simply find line operators with secondary specialized education, a technologist who will be responsible for maintaining the proportions of the ingredients added, checking the quality of the work performed, and monitoring the staff.

Also needed are general workers who will perform unloading and loading work and will take care of the territory. A warehouse manager and an accountant are also needed. You can also invite a manager to help you, who will help with organizational activities, the purchase of raw materials and the sale of finished products. In a small enterprise, it is enough to employ about 8-12 people. And their salary will be about $4.5 thousand.

Marketing.

In order to attract attention to your product, it is worth timing the start of your business closer to the season. And it will begin in the spring.

In winter, there is always a decline in demand for crayons. First of all, it is worth developing bright packaging that will attract attention. You can simply make a bright and enticing drawing or simply apply a character from your favorite children's cartoons.

You can also hold a promotion and temporarily reduce the price of the product. Or add some small change to each package of crayons. It could be a lollipop, a sticker, chewing gum, or anything else. You can attract clients if you set people up for a long-term promotion. For example, in the middle, each box will contain a small toy. Children love to collect and collect, and this will be a great reason to purchase goods regularly. It costs about $300 to advertise and attract customers.

Basic costs.

The main costs of business development will be:

1. Rental of premises - $400;
2. Purchase of equipment - $8 thousand;
3. Purchase of raw materials - $2 thousand;
4. Hiring staff - $4.5 thousand;
5. Advertising - $300.
It is worth investing at least $12 thousand on business development.

Profit and payback period.

The payback of the business will be realized no earlier than six months. The market value of one package can range from $0.5 to $2. Everything will depend on the configuration and design of the products. The production line allows the production of at least 500 packages per shift.

Working two shifts for a whole month, you can bring 30 thousand packages of colored and white crayons to the market. If you sell products at an average price, around a dollar, you can get about $30 thousand per month.

Subtracting monthly expenses and expenses, the net profit will be only $5 thousand. Working in this mode and with 100% sales of products, you can completely recoup your business in just two seasons.

Clients and business development.

The main clients of this business for the production of crayons for drawing are various educational institutions, including schools, kindergartens, development centers and even institutes. Parents of children aged from one to 12 years also become clients.

As a development in this industry, it is possible to create crayons that contain special substances, as a result of which the drawing will begin to glow.
