The small use of eggshell

Everyone should be familiar with eggshells, right? The egg shells are divided into three layers, the nipple layer of the inner layer, the sponge layer in the middle, and the stratum corneum of the outer layer. The inner layer of the nipples contains a lot of calcium taper shapes, and between the cone shape, there is a small gap (stomach) that accommodate the air. The outermost layer is the horny of the shell, without any structure, and there is a small hole. The middle layer is sponge -like and is intertwined by calcium fiber.

The egg shell is a multi -micropore structure, which is composed of organic stents or inorganic parts containing minerals. The main component is calcium carbonate. In addition, it also contains a small amount of organic matter, constant element P, MG, Fe, and trace Si, Al, BA and other elements.
