2. Then we draw some lines on the shell to decorate the texture of the shell and draw a pearl in the middle. Remember to draw highlights!
3, then draw the other half of the shell, also draw a double line, pay attention to the radian of the line!
4. Finally, color painting. Let's paint the shell light cyan, pay attention to the gradual change of color, and paint the pearl in the middle pink, and the beautiful shell stick figure will be finished!
Shell (bèi ké) is the mantle of mollusks living near the water, and it is a kind of calcification secreted by a special gland cell of mollusks, which is used to protect the soft parts of the body. The main components of shells are 95% calcium carbonate and a small amount of shellfish.
The number, shape and structure of shells vary greatly, and some types are 1 spiral shells (such as snails, snails and abalone); Some species have two petal-shaped shells (such as mussels and cockroaches); Some species have eight plate-like shells arranged in tiles (such as stone turtles); Some kinds of 1 shells are wrapped in the body (such as squid, squid); Some kinds of shells even completely degenerate (such as ship maggots).
The main components of shells are 95% calcium carbonate and a small amount of shellfish. Generally can be divided into three layers. The outermost layer is dark brown cuticle (shell skin), which is thin and transparent and has the function of preventing carbonic acid erosion, and is composed of chitin secreted by the edge of the mantle; The middle layer is prismatic layer (crust), which is thick and consists of prismatic calcite secreted by the mantle edge. The outer layer and the middle layer can enlarge the area of the shell without increasing the thickness. The inner layer is the nacre (bottom layer), which is composed of phyllodes secreted by the whole surface of the mantle. It has a beautiful luster and can be thickened with the growth of the body.
They have always been the best friends cherished by designers. Especially in the past two years, jewelry-grade shellfish ornaments have been more and more loved by people who like handsome and natural in our city. Mother-of-pearl is a natural material, so the color and texture of each piece are very unique, which meets the demand of more and more consumers for personalized jewelry. The processing of mother-of-pearl ornaments is very complicated. The original mother-of-pearl should be polished very carefully, cut accurately and inlaid according to the design requirements. After many processes, it can be made into pleasing shell ornaments.
