That is why it is necessary to completely clog the vessel and transport it carefully, protecting it from any shaking.

Having told a little about the ceremony, you can tell about where to get the sand. Search in all the deserts of the world? You cannot find this material, no matter how long you travel, but it can be done by applying the most, that neither is the amount of effort, time and patience expended.

Colored salt sand: step by step instructions

You can make multi-colored sand at home with a minimum amount of costs. This product is quite simple to manufacture and does not require any knowledge of chemistry, biology and other subjects. All you need is this guide.

The ingredients for this product of production are likely to be found at home, and if not, then they can be bought without spending much. All you need is salt, ordinary table salt, which every housewife has on hand, and semi-liquid gouache, paints that can be purchased at any office or asked from friends who already have small children in their families, will do.

A description of the manufacturing process will be indicated step by step. Strictly stick to the sequence!

1) It will be better if you cover the work surface with a sheet of plain paper. Take a faceted glass and fill it 1/3 of the entire volume with salt, if the salt has hard lumps, carefully crush them.

2) In a glass of salt, add about 1/3 teaspoon of gouache, the color you like. You can experiment with the amount of dye added to the salt to achieve the desired shade of one color or another.

3) Add one tablespoon of water to the existing mixture.

4) Gently mix the mass until it acquires a uniform color.

5) Dry the resulting mass well. One of the most quick ways call it a microwave oven. You can also dry it by leaving it in the sun, or near the heating system (batteries or radiators) in the house or apartment, stirring the mixture all the time.

6) Everything is ready. You can find a bride or groom (if you don't already have one) and go straight to your own wedding.

Multi-colored semolina sand

The second way to make colored sand will be based on the color of semolina. This option is best suited if you have children at home. After all, they also want to scatter sand, so you can use it not only for the wedding ceremony. They can safely be allowed to play with this substance. Lots of fun activities you can come up with for children from colored semolina. An incredible number of sand drawing notebooks can be purchased at the store or printed out yourself and get your hands on glue. Manka will become indispensable in your home.

Such sand is made quite simply using only 3 ingredients: semolina, food coloring, alcohol.

1) A serving of food coloring, always dry, must be mixed with 1 teaspoon of alcohol. (If you don't have alcohol handy, you can use hand sanitizer gel. It will dissolve your food coloring and dry well.)

2) Divide semolina into different containers

3) Mix the semolina with the dye liberally until you get the desired color. During this process, the alcohol must completely evaporate.

4) Put the resulting mixture on a sheet of paper to avoid possible sticking of this mass. Dry.

5) Push the lumps apart if they appear during the drying process.

Important! Do not use water, semolina will simply become porridge and there will be no sand.

How to paint sand at home?

In nature, sand of several shades is found, but they all belong to the yellow-brown range. You can get blue, green or red material only by staining. It is quite possible to do this at home, in this article we will tell you how to paint the sand.

How to color sand for crafts?

Prepare the sand.

How to paint sand or small gravel

Fine quarry sand is most suitable for creativity. Before staining, remove all stones and dirt from it by sifting through a sieve.

Take light-colored sand. It is easier to paint over it, the colors are bright and saturated. It is most convenient to mix sand with dyes in plastic bags equipped with fasteners. After work, they can simply be thrown away.

There are several ways to quickly and effectively stain:

• Ink. achieve rich color possible when using ink designed for refilling the printer. Pour the sand into a sealed container. Pour in two drops of ink. Shake the container vigorously until the sand is completely mixed with the ink. Free the material from the formed lumps.

• Colored crayons. This method can be called the simplest. Even kids can handle it. Grind the crayons into dust and mix it with sand. The material obtained in this way is completely safe. The colors are pastel, bright shades can not be achieved by this method.

• How to paint sand with gouache? Pour the sand into a ziplock bag or any jar with a screw cap. Gouache must be liquid. If it is already dry, then dilute it with water. Pour it into a container with sand, mix thoroughly. After that, pour the colored sand into a container that can be used in the microwave. Heat the material in the microwave for about three minutes. During this time, excess moisture will evaporate, and the pigment will firmly adhere to the sand.

• Aerosol paints. This method can achieve the most bright colors, but due to the pungent smell, it is impossible to use such sand immediately. You can start creating only after a couple of days. To paint, simply spread the sand on sheets of paper or film in an even, thin layer and spray the paint onto it.

Use for sand coloring acrylic paints Not recommended. During processing, lumps will form, and the material itself will not absorb paint well.

After drying, the sand can turn into one piece that cannot be crushed.

Choose the way that suits you and color the creative sand with your kids!

One of the main components in the production of MIXAN mosaic plaster is colored quartz sand. It acts as a color filler and plays not only aesthetic, but also protective function, since this natural mineral is one of the strongest and most resistant to physical stress.

Production of quartz sand.

For production, we use specially prepared, washed, calcined, sifted quartz sand, which has a certain chemical composition, determined by the minimum allowable amount of impurities. In the process of preparation, sand is sorted into fractions, washed from clay inclusions, high-temperature drying and packaging for further transportation.

How to make colored sand

Such quartz sand mined in certain quarries, and delivered in big bags to our production.

Coloring of quartz sand.

Color production quartz sand DISMIX requires strict adherence to the entire technological chain during painting and well-coordinated work of highly qualified specialists.

In the process of many years of work, the most popular colors and the necessary pigments for coloring quartz sand were selected. But this does not limit our possibilities. We aim to be flexible and can color quartz sand in new colors upon request. The popular RAL catalog is used as a guide for color selection.

Properly selected components, both in quantity and composition, play a very important role in the manufacture of high-quality products. For this purpose, we use only proven technologies and high-precision equipment.

Coloring of quartz sand occurs in several stages, in small portions of 200-250 kg. During the production process, the grains of sand are coated with a layer of pigment of the required color, and then with a layer of a thin, but very durable and chemical resistant, polymer component - polyurethane resin. It all ends with the drying of colored sand and packaging in harvesting containers.

The system for the preparation of colored quartz sand allows us to quickly fulfill orders for the production of MIXAN mosaic plaster.

Use of colored sand

Using modern, high-tech equipment, we are ready to meet the needs of our customers in colored quartz sand, which is widely used in such areas as:

Natural, uncolored quartz sand is often used in water treatment filters and as a substrate in aquariums.

Sale of colored quartz sand.

All products of our production are sold through our dealer network, which has a single pricing policy. We are ready to satisfy your need for colored and natural quartz sand in quantities from 1 kg to several tens of tons per month.

Colored sand can be used for various art projects. Of course, you can buy it in a special shop, but colored sand is very easy to make yourself, and you can also create a wider range of colors yourself. Here are a few simple ways how to paint sand.

Steps

1 Use tempera powder

1. 1 Choose the tempera color you want. Powdered tempera is usually mixed with water to make paint, but it is also used dry to color sand.
   • Dry tempera can be purchased at art stores or online.
   • It is used in kindergartens and schools because it is non-toxic, inexpensive and easily washed off with water.
   • Feel free to mix together different dry tempera colors to make your own.
2. paint sand 2 Pour the sand you are going to paint into a suitable container. It can be a cup, bowl, bag, or any other container you have on hand.
   • Make sure the container is big enough to mix the sand into the paint, otherwise the sand will spill onto the floor.
   • Instead of sand, you can also use table salt. Don't use sugar as it sticks together over time.
3. paint sand 3 Add a small amount of dry tempera to the sand. Start with one teaspoon of paint per cup of sand.
4. paint sand 4 Mix the sand well with the paint. You can add more paint until you get the right color.
   • If you are using a bowl, mix the sand with a spoon or stick.
   • If you can close the container, start shaking it vigorously to help mix the sand into the paint.
5. 5 Make sure the sand does not spill out of the container.

2 Use food coloring

1. paint sand 1 Pour the sand you want to paint into a suitable container. It can be a cup, bowl or any other container.
   • Make sure your container has enough space to mix the sand so it doesn't spill onto the floor.
   • You can paint as much sand as you need.
2. paint sand 2 Fill the container with water just enough to cover the sand.
   • If you add too much water, you won't be able to color the sand brightly, or you'll have to add more paint.
   • For this method, only sand is suitable for you. If you use salt, it will dissolve in water.
3. paint sand 3 Add 1-2 drops of food coloring to the container and stir. If the color is not dark enough, then continue to add dye drop by drop until you get the desired color.
   • If the color is too dark, then add a little water to dilute it.
   • You can also mix food coloring together to make other colors.
4. paint sand 4 Drain all water. Use gauze or a strainer for this.
5. paint sand 5 Let the sand dry. Sprinkle it on several layers of paper, on a rag or on old towels.
   • Be careful not to stain anything with dye.
   • Try placing a plastic bag under the paper or cloth for extra protection.
   • Sand will dry faster if you place it in a warm, dry, well-ventilated area.
6. 6 Ready. The sand must be completely dry before you put it away for storage. Make sure that sand does not spill out of the container.

3 Use alcohol-based ink

1. 1 Choose the color you want. You can use alcohol-based ink (bottled), which is used for rubber stamps, or ink for drawing.
   • Alcohol-based ink can be purchased at art supply stores.
   • Feel free to mix inks of different colors together to create your own custom colors.
   • You can also use food coloring, but it is less stable.
2. paint sand 2 Pour the sand into an airtight container. Make sure the container is tightly closed. The easiest way is to take a bag that is hermetically sealed.
   • Make sure there is enough space in the container to allow the sand to be vigorously agitated.
   • You can paint as much sand as you need.
   • Instead of sand, you can also use table salt. Don't use sugar as it will stick together.
   • It is best to use white sand, which is sold in art supply stores.
3. paint sand 3 Put 1-2 drops of ink into the sand, and then shake the container to mix the sand. Continue mixing until the sand is the color you want.
   • If the sand has already acquired the color you need, and there are still ink residues in the sand lumps in the container, then remove them.
   • If the color of the sand is not yet dark enough, then continue to stain it with ink one drop at a time until you get the desired color.
4. paint sand 4 Your colored sand is ready for storage. Make sure that the container does not spill sand anywhere.

4 Use colored crayons

1. 1 Select the desired chalk color you wish to use. For darker tones, you can use pastel crayons.
   • Colored crayons and pastel crayons are available at art supply stores.
   • Feel free to mix different colors of crayons together to make your own color schemes.
2. paint sand 2 Prepare your work surface. You will need to rub the chalk, pastel, or salt into the sand, so prepare a hard work surface and cover it with something.
   • A piece of thick paper or a plastic bag is ideal for this. They can also be used to pour finished sand into storage containers.
   • When mixing different portions of sand, make sure that the surface is clear of other paints so that they do not mix with each other.
3. paint sand 3 Sprinkle a small amount of sand or table salt on a hard surface. This method may take some time, so paint the sand in small amounts.
   • It is best to paint white sand, which is sold in art supply stores.
   • Don't use sugar as it sticks together.
4. paint sand 4 Take a small piece of chalk or pastel and start rubbing it into the sand. For best results, do this in even strokes.

   How to paint quartz sand?

   • The chalk will gradually stain the sand or salt.
   • To speed up the process, you can rub the chalk into the sand with a craft knife, palette knife, or other tool.
   • For large batches of sand, chalk can be ground with sand in a mortar and pestle.
     • If you do this, then first grind the chalk into powder.
     • After you color the sand, wash your mortar and pestle well, especially if they are used for cooking.
5. paint sand 5 Continue rubbing the chalk into the sand until it is the desired color. Feel free to use different colors of chalk or pastels to create your own color.
6. paint sand 6 Your colored sand is ready for storage. Make sure your container doesn't spill sand anywhere.

• Liquid food coloring is preferable to paste food coloring because the thick consistency of the paste makes it difficult to mix with sand and you will have a hard time achieving a uniform color and texture.
• Start with less paint than you think you'll need. You can always add it, and you won't have to waste material if the color gets dark too quickly.
• Your child can use the colored sand to do some crafts with it (under your supervision). Make some patterns on paper with transparent glue. Pour colored sand into a salt shaker and have your child shake it out onto paper to make a colorful picture.
• Make a small art project by pouring layers of colored sand into glass jar, bottle or vase.

Warnings

• When you dry painted sand, be sure to put several layers of paper, rags or a thick towel between the sand and the surface of the table or floor, because the paint can leak and stain the surface.
• When using chalk or tempera, try not to inhale the powder. Although it is non-toxic, your lungs will not like it.

What will you need

• White sand, salt (except food coloring method), or plain sand
• Coloring matter: dry tempera, crayons, alcohol-based ink, or liquid food coloring
• Mixing containers: plastic container or sealed bag
• Plastic spoon for stirring
• Paper towels, rags or old towels
• Storage container: Sealed food storage bag or plastic container

How make colored sand

We'll need

- light colored sand;

- dyes: colored crayons or gouache;

small containers;

Stick or spoon for mixing sand;

Sand drying paper (newspapers, paper towels, etc.).

Let's get started:

1. We take sand and pass it through a sieve. We remove small stones and other debris.

2. Fill it up sand prepared containers. The best thing sand paint in small portions, then it will be painted evenly and dry much faster.

There are many dyes for coloring sand. (colored crayons, food coloring, paints, etc.). I use crayons and gouache.

colored crayons

Three crayons on a grater and add to a small amount of sand. Mix thoroughly. Then add a small amount of water to the sand just got wet. Mix the mixture well again, achieving an even coloring of the sand. Then we post sand on paper to dry.

For gouache staining, first wet sand, and then add paint to it. After that, mix the mixture thoroughly, evenly distributing the coloring pigment in sand mass. When mixing the ingredients in a jar or bowl, use a stick or spoon. After mixing sand with paints, pour out the painted sand on sheets of paper in a thin layer and dry for a day.

Now colored sand ready for further use in your creativity.

The invention relates to industry building materials, mainly to methods for coloring bulk materials, such as quartz sand, stone chips, etc. Technical task: improving the quality of the colored granular material. Processing of granular material is carried out by moving a cylindrical chamber with a frequency of 300-700 rpm along a circle, the diameter of which is 0.2-0.6 of the internal diameter of the chamber, and the coloring matter is fed into the chamber in the form of a suspension containing 0.1-1.0 wt.% adhesive, 0.3-2.0 wt.% coloring matter and 2.0-5.0 wt.% water from the material to be painted. 1 tab.

The invention relates to the building materials industry, mainly to methods of coloring bulk materials, in particular quartz sand, stone chips, and can be used in the production decorative coatings , concretes and mortars, glass tiles, etc. There is a known method of coloring a granular material, such as sand, by heat treatment at a temperature of 500-900 o C for 5-40 minutes, followed by cooling the sand, mixing it with a paint composition, drying the resulting mixture and its firing (see, for example, ed. St. USSR 1778089, class C 04 B 20/10, 1998). The high energy intensity of the process, due to the need to conduct it at high temperatures (up to 900 o C), reduces the efficiency of this method. Also known is a method for dyeing a granular material, in which the dye suspension is subjected to activation by treatment in a rotating electromagnetic field with ferromagnetic bodies for 2-3 hours with simultaneous heating to 25-30 o C, and the coloring of the granular material is carried out by mixing the obtained activated dye suspension with sand at its wet grinding (see, for example, ed. St. USSR 482078, class C 04 B 20/10, 1974). Activation of the dye suspension makes it possible to obtain a dye characterized by improved coloring properties with a significant (30-40%) reduction in pigment consumption for its manufacture. However, the known method is rather complicated to implement. The closest in technical essence to the proposed is a method of coloring a granular material by feeding and co-processing the material and the coloring composition in a cylindrical chamber (see, for example, Ed. St. USSR 1244123, CL C 04 B 20/10, 1984). However, being sufficiently simple, the known method does not prevent particles of granular material dyed with silicate paint from sticking together into lumps, which significantly increases the reject rate of the finished product. The purpose of the invention is to improve the quality of the colored granular material. This goal is achieved by the fact that in the method of coloring a granular material by feeding and joint processing of the material and the coloring composition in a cylindrical chamber, the processing is carried out by moving the chamber with the material at a frequency of 300-700 rpm along a circle whose diameter is 0.2-0.6 the inner diameter of the chamber, and the coloring matter is fed into the chamber in the form of a suspension containing 0.3-2.0 wt.% of the coloring matter, 0.1-1.0 wt.% of the adhesive and 2.0-5.0 wt. % of water from the material being painted. The method is carried out as follows. A suspension of the coloring composition is prepared, for which the adhesive and water are first fed into the mixer in the required amount and they are mixed for 5-7 minutes. As an adhesive can be used: liquid glass pl. 1.25-1.3 g/cm 3 , polyvinyl acetate emulsion (PVA), acrylic emulsion. A dye is added to the resulting solution and stirring is continued for another 3-5 minutes. The content of the coloring matter in the suspension is chosen in the range of 0.3-2.0 wt. %, and adhesive - 0.1-1.0 wt.% of the material to be painted. At the same time, the amount of water in the suspension should be such that its content in the material being painted is minimal (no more than 2-5 wt.%), which ensures the most rational processing of the granular material by the coloring suspension without its loss. The finished suspension is pumped by a pump into an intermediate tank. Coloring of granular material is carried out in a cylindrical chamber, moving at a frequency of 300-700 rpm, along a circle, the diameter of which is 0.2-0.6 of the internal diameter of the chamber, and the center of the circle is displaced relative to the axis of the chamber by 0.2-0.5 chamber diameter. A granular material and a simultaneously prepared coloring suspension are continuously fed into the chamber, carrying out their joint processing for 1-4 minutes. The finished product - colored granular material - after drying, if necessary, packaged in a container. The essence of the proposed method of coloring granular material is as follows. In the process of joint processing of the granular material and the coloring matter in a cylindrical chamber, at the initial stage, the substance is mechanically applied to the surface of the grain under the action of centrifugal forces that press the material and the coloring matter to each other and to the inner surface of the cylindrical chamber. The use of an adhesive to prepare a coloring suspension increases the adhesion of the coloring agent to the surface of the grain at this stage of co-processing. In the future, due to the movement of the cylindrical chamber with a high frequency and the displacement of the center of movement of the chamber relative to its axis, not only an intense mutual collision of the coloring matter and the granular material occurs, but also their activation and chemical interaction, providing the strongest adhesion to the surface of the granular material of the coloring matter at a minimum consumption. the last one. At the exit from the chamber, the particles of the granular material acquire a dense colored shell, the adhesion of particles is prevented by their intensive movement relative to each other when leaving the chamber. Examples of the implementation of the method. Example 1. An aqueous suspension of a coloring composition is prepared, for which liquid glass pl. 1.25-1.30 g/cm 3 in the amount of 0.1 wt.% and water in the amount of 2.0 wt. % of the granular material and mix them for 5-7 minutes. A dye is added to the resulting solution in an amount of 0.3 wt.% of the material to be colored and stirring is continued for another 3-5 minutes until a homogeneous uniformly colored suspension is obtained. The prepared suspension of the coloring matter (2.4 wt.%) and the granular material to be dyed (97.6 wt.%) are fed into a cylindrical chamber moving at a frequency of 700 rpm along a circle whose diameter is 0.2 of the internal diameter of the chamber, and the joint processing of the granular material and the coloring suspension is carried out for 1-4 minutes. The colored granular material is unloaded from the chamber, if necessary, dried and packed into containers. Example 2. The technology of coloring a granular material - according to example 1. In this case, PVA (polyvinyl acetate emulsion) in an amount of 0.5 wt.% and water in an amount of 2.9 wt. % of granular material. A dye is added to the resulting aqueous solution in an amount of 1.2 wt.% of the material being dyed, and the joint processing of the granular material (95.4 wt.%) and the coloring suspension (4.6 wt.%) is carried out by moving the cylindrical chamber with a frequency of 500 rpm around a circle whose diameter is 0.4 of the internal diameter of the chamber. Example 3. Technology - as in example 1, but an acrylic emulsion (1.0 wt.%) is used as an adhesive, and water is added in an amount of 5 wt.%. A dye in the amount of 2.0 wt.% is added to the prepared aqueous solution of the adhesive, and the joint processing of the granular material (92.0 wt.%) and the aqueous suspension of the dye (8.0 wt.%) is carried out in a chamber moving at a frequency 300 rpm, around a circle whose diameter is 0.6 of the internal diameter of the chamber. The use of the proposed technical solution outside the stated conditions for coloring the granular material does not allow to achieve the goal. The test results of the colored granular material obtained by the proposed method are shown in the table. The proposed method for coloring a granular material can significantly improve the quality of coloring a granular material with a minimum consumption of coloring matter. The color coating formed on the surface of the grain is distinguished by its continuity and increased abrasion resistance. The method is suitable for coloring granular materials of any fraction: from fine sand to coarse aggregate, and the introduction of a coloring agent into the composition to be painted in the form of an aqueous suspension ensures the most economical consumption of the dye with its extremely uniform distribution on the surface of the material being processed.

Claim

How to make colored sand with your own hands?

The fastest and easiest way is to make colored "sand" from decoys and ordinary children's crayons.

To do this, you need to crumble the chalk (cut with a knife, then chop, for example, with a rolling pin), pour semolina and a piece of chalk into a container, close the lid and shake several times. That's all! Manka turns out very delicate pastel shades.

Can be used instead of chalkdry pastel, and crushed crayons can be mixed to obtain new interesting shades.

According to the same instructions, you can make colored "sand" from fine salt. If you need just a little of some color, then you can mix crushed crayon and salt right on the table.

Now back to present colored sand.

It will take a little longer for him.
If you are using street sand, first thoroughly rinse it in several waters. Then you can start coloring. Let's take the usual gouache and mix it thoroughly with wet sand, it is better to do this by hand (use gloves). Instead of gouache, you can use food colorings. After staining, spread the sand in a thin layer until completely dry.
By mixing gouache, food coloring, you can get a wide variety of colors, and, of course, they will be much richer than from crayons.

It is better to store colored sand in closed containers. And if you want to avoid unplanned cleaning, then tidy it up from the ubiquitous children's hands :)As you can see, it is very easy to make colored sand with your own hands.
