Really! Nowadays, in the competitive society, some pawn shops sell sheep's head dog meat, which was well spoken before borrowing. After borrowing it, it is difficult to discuss and communicate. Actually, I have met many kinds of pawnbrokers. Since I found the PICC pawnshop in Zhongmu, I feel completely different from those pawnshops. I don't have to look at people's faces at all, just like going to the bank. Good service attitude, customer-oriented explanation will not be cheated. I feel that the manager is very kind and easy to discuss. I really recommend Zhongli PICC Pawnshop. I can also search online and see excellent comments. Many people recommend Zhongli YKK. It is easy to find 03-4520077.
English:. Excuse me, there is a special gland cell whose secretion can form calcifications to protect the soft parts of the body. This cell is called a shell. 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. The main chemical composition of calcite and aragonite is CaCO3. There are many concentric and annular growth lines on the outer layer of the shell, and the light and dark colors alternate, but they do not represent age; It is formed because the edge of the mantle can't continue to secrete for some reasons (lack of food, different seasons, reproductive period, etc.). ). Commercial shells, such as clams. Some of them have pearl-like iridescent luster, so they are used in jewelry industry to make necklaces and clothing accessories (buttons, etc. ), even installed on jewelry, more used to make shell carvings, collages, inlaid handles, etc. Among all kinds of shells, Pinctada martensii in the Torres Strait in northern Australia, Pinctada Manila in the Philippines, Pinctada burma in Myanmar, Giant mussel and Queen mussel in the West Indies are the best. A century ago, the deep-sea pearl oyster was a symbol of luxury and splendor of European aristocrats. It has a charming luster and changing colors like pearls, but it also has colorful colors different from pearls. The colorful pearl shell that breeds pearls has never been ignored and buried for thousands of years. In the late Qing dynasty, mussels and other shellfish were polished into buttons and decorated on high-end clothes in Hangjiahu area. 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 jewelry is very complicated, and the original mother-of-pearl should be polished, cut and inlaid in detail according to the design requirements. After many processes, it can be made into pleasing shell ornaments. Decorating a small shell in life can also play a big role. Fan-shaped, spiral, large and small, with a little processing and hanging, you can escape the fate of being thrown away, which is beautifully displayed on the wall and desktop. A large area of scalloped shells are completely decorated on the inner wall of the wooden bowl through a special process, which makes the bowl more environmentally friendly to use. And if you put on a beautiful pearl, make a curtain and decorate it in front of the window, the home scene with Southeast Asian flavor will be presented immediately. If you put it by the sea, you will use it to listen to the sound of the sea, but it is very useful in a natural style home. Curtain buckles and small rings, shells can make your home show the scenery of Southeast Asia without modification. The small conch picked up by the sea is smooth, round and shiny, and the two are matched together to make a ring of curtain buttons, which is beautiful and extraordinary. When they are stuck on the curtains at home, the curtains will also be contaminated with the Shanghai style. There is almost no need to transform, as long as there are shells with similar shapes and sizes. Shells are made into tableware. Forks and spoons, each with its own purpose, are very interesting to put on the dining table.
