Unlike porcelain, pottery is made of clay. Porcelain is made by grinding the stone into powder, stirring it into slurry, and pouring it into a mold. Ceramics fired at the same temperature have stronger hardness. People are no strangers to vases, but people often don't know how to choose the dazzling vases, such as ceramic vases and plastic vases. What is the difference between them? Which is better?
A ceramic vase
1. porcelain of different dynasties is rich in content, common in style and unique in each.
2. The shape of the porcelain, Shunzhi, Kangxi and Guzhuo, is plump and thick. It was flexible and meaningful during Yongzheng, neat during Qianlong and elegant after Jiaqing and Daoguang.
3. the carcass and cut meat are generally moderately thick, while the round meat is thick and thin.
4. the glaze is not as bright as that of the Ming Dynasty. The glaze is thin and the color is slightly blue and white. During the Shunzhi and Kangxi periods, the glaze was smooth and fine, and the body and glaze were closely combined. The glaze has a variety of colors, such as blue white, pink white, white sauce, hard bright green, etc. Yongzheng's glaze is delicate and white, with orange peel wrinkles. It is flat and green when it is dry, but it is not flat enough after it is added. The waves are obvious. In the late Qing Dynasty, the glaze was thin and the enamel was loose and not firm enough.
B plastic vase
Plastic vases are mainly made of polyethylene or polypropylene, with various organic solvents added. Most drink bottles are made of plastic. Polyethylene and polypropylene are non-toxic and tasteless, and the beverage filled by human body is safe. However, once polyethylene is corroded by high temperature or acid, it will slowly dissolve and release organic solvents, which is harmful to human body.
