How to draw sand, and what is the difference between sand and ordinary sand?

Here's how to draw sand:

1. First draw a small black dot on the paper, which is the sand particles, and then draw some sand particles below.

2. Draw the sliding trace lines of the sand between the sand particles, and the position of the sand particles can be drawn arbitrarily.

3. Draw the shape of a pile of sand that gradually widens, and then draw a number of scattered sand particles to the edge, and the picture is finished.

There are many uses of sand, but the main use is the infrastructure industry, as one of the main raw materials of concrete, the quality of sand can sometimes determine the quality of infrastructure projects. Sand can be divided into three types: coarse, medium, and fine according to particle size. The determination of these components is important because they affect the engineering properties of the sand as a pavement layer, such as plasticity, strength, and load-bearing capacity.

The shape of the sand affects its density, stability, and overall engineering properties, and the resistance of smooth round particles to rearrangement is less than that of surface rough particles. It is the wind or water of nature that determines the shape of the sand, and the sand in the desert is mainly obtained by weathering, which results in the shape of the sand being smooth round particles.

The sand in the desert has an open structure, and there is almost no interlocking between the sand grains. If the sand is kept dry, it can provide a good load-bearing capacity for the building; But if the sand gets wet, the building will soften, it will break and collapse. On top of that, desert sand is also more expensive to mine, so we mine the desert a little less.

First, determine the approximate location. Then, with a black pen, draw some arcs on it, different sizes, shapes, and positions, drawing the feeling of undulating heights, like rolling hills. Next, you can draw some dots with a thicker black pen in some places, about a dozen dots as a cloud of sand.

Next, you can start to paint the sand, you can paint it dark brown or yellow, so that the sand is ready.

There is also a way to draw a plastic bucket first, and then draw the sand on top. You can draw some arcs, end to end, like clouds in the sky. Then, dot some dots on it, and finally paint the color, and the sand is ready.

Sand paintings. The game is to sprinkle a handful of river sand evenly on a special drawing board through the fingers, and then hook the sand with your index finger to create a long ribbon-like line. The production of sand paintings does not need to be composed or limited by the pattern of painting, and you can give full play to your imagination to make gorgeous and colorful pictures.

The common techniques of sand painting are:1Sasha; 2.

sand spreading; 3.Goussa; 4.smear; 5.

sand leakage; 6.Slapping sand; 7.Pinch sand.

Among them, the sand leakage should hold the sand in the hand and clench the fist, and control the flow of the sand by the tightness of the fist, and the line will change in thickness, and at the same time, the height of the hand will change accordingly when moving quickly.

1. The composition is different.

Sand paintings are mainly made by mixing different sands such as sea sand and river sand in proportions, and the other components are natural colored sandstones, tree bark, and various materials. The composition is still mainly ordinary sand.

2. The color is different.

The color of the sand used for sand painting is more vibrant. The raw material used by most manufacturers is alumina wire (copper plated wire or galvanized nickel wire). Because its color is golden yellow, it is called gold wire.

In addition to gold wire, sand mining is also an essential raw material. Natural colored sand and stone in nature are rare, and it is not easy to obtain, and even if you get the color, it is not complete, and it cannot meet the rich colors required for art painting. Compared with dyed sand, the color of real natural colored sand is slightly dull, and the painting effect is not as good as that of glaze.

Therefore, most of the colored sand paintings on the market are made with dyed sand.

1. First draw a small black dot on the paper, which is a sand particle.

2. Then draw some sand particles below.

3. Draw the sliding traces of the sand between the sand particles.

4. The position of the sand particles can be drawn arbitrarily.

5. Draw the shape of a pile of sand that gradually widens.

6. Draw a number of scattered sand particles further to the edge, and the picture is finished.

7. The shape of the sand pile should be drawn naturally.

8. There are many uses of sand, paving roads, or mixing with cement to build walls, and decorating houses are inseparable from the use of sand.

9. Tools Raw Materials:

1. Pencil. 2. Paper.

Hello, I am glad to answer for you that the sand paintings are mainly made of different sands such as sea sand and river sand mixed in proportion, and the other parts are inlaid with natural colored sand and bark and various materials. The composition is still mainly ordinary sand. The sand used for real sand painting is made of different sands such as sea sand, river sand, crushed earth and stone, stream sand, etc., mixed with oak bushes in proportion, and is painted on a glass plate with a bottom light, only once, and must be taken with a camera.

Generally, you have to do a good job of composition first, and you have to match the color, so that it will be quick.

First of all, use latex and other glue to paint (you can glue repeatedly), this step is very important, the shape is good or not to see this step for a long time.

Then put on the sand. (Repeatedly sand colored).

It is necessary to pay attention to the strength of the hand grasping the sand and the speed and flow of quicksand when painting.

Secondly, pay attention to excitation.

The basic techniques include sprinkling, wiping, wiping, pointing, pressing, scratching, leaking, hooking and other basic techniques, and these techniques should be used purposefully, and different techniques will have different effects.

It is necessary to pay attention to the virtual reality when making sand paintings, and the proper virtual and real will make the picture appear vivid and real.

Friends who have just started to learn sand painting, don't be in a hurry to create by yourself, you can try to copy more, and then create your own after you are proficient in the technique, that will be better.

Sand painting, that is, painting with sand. It's a unique art. It combines the aesthetics of modern people, relying on profound cultural heritage and cultural connotation;It is made of natural colored sand produced in the magical nature and is delicately handmade.

Generally speaking, there is a self-adhesive plate with a pattern, and each part of the top is carved out in advance with a knife, and the painter only needs to gently lift each part with a toothpick when painting, and then pour the sand of the favorite color on it (the self-adhesive will naturally stick to the sand). Sand painting has a unique performance charm, which can make the audience enter a dreamlike feeling and unprecedented visual enjoyment.
