First, paint the doll with white and big red. Draw the whole doll roughly first, with different shades. Draw the rose in the right eye with big red, and draw the leaves with phthalocyanine green and white. Notice that the tulip in the left eye is the same color. Decorate with small strawberries painted big red.

First, we draw the eyes and mouth of the super cute star Drew. Then, we draw the head of the super cute star Drew. Next, we draw the ears of the super cute star Drew. Finally, draw the body and limbs of Super Meng Xingde Road, Super Meng Xingde Road.

Draw a circle that is not quite round first as the head of Stardew. Then draw an ellipse as a small cheek with a protruding star. Then erase the curve on the face and draw Stardew's eyes and nose. Then draw a beautiful flower hairpin on Stardew's head.

Then draw two rabbit ears of Stardew, one straight and one curved, which looks naughty and cute. Later, Stardew painted her body, and Stardew was sitting. Then draw Stardew's own small palm print on the sole of Stardew's foot and draw some circles.

The coloring skills of plaster dolls are as follows:

1. Throw away selfish distractions and concentrate on coloring.

2. Paint your face first, then paint your skin color with a fine pen, and then apply Gou Xianbi to your eyes, nose, mouth and other small parts.

3. Mark adjacent areas of different colors with Gou Xianbi to avoid drawing large areas.

Gypsum is introduced as follows:

Gypsum is a monoclinic mineral and a hydrate with calcium sulfate (CaSO4) as the main chemical component. Gypsum is a widely used industrial material and building material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper-making filler, paint filler, etc.

The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fire prevention properties.

Gypsum is usually called gypsum and anhydrite. Gypsum is calcium sulfate dihydrate (Ca [SO4] 2H2O), also known as gypsum dihydrate, gypsum hydrate or soft gypsum. The theoretical components are CaO32.6%, SO346.5% and H2O+20.9%. The crystal is monoclinic, plate-shaped, usually in dense blocks or fibers.

The basic properties of gypsum are introduced as follows:

Natural gypsum dihydrate (CaSO4 2H2O), also known as raw gypsum, can be calcined and ground to obtain β -type hemihydrate gypsum, also known as plaster and gypsum. White, off-white, glassy, Mohs hardness 3 ~ 3.5, cleavage parallel {0 10} complete, density 2.8 ~ 3.0g/cm3. Two kinds of gypsum are often produced together and can be transformed into each other under certain geological conditions.

The structure of gypsum is introduced as follows:

Monoclinic system, a0=0.568nm, b0= 1.5 18nm, c0=0.629nm, β =1/823'; Z=4. The crystal structure consists of [SO4]2- tetrahedron and Ca2+ (0 10) double layer.

These two layers are connected by H2O molecules. The perfect division takes place in this direction. The coordination number of Ca2+ is 8, and it is connected with 6 O2- and 2 H2O molecules in four adjacent [SO4] tetrahedrons. H2O molecules are connected with O2- in [SO4] by hydrogen bonds, and water molecules are connected by molecular bonds.
