Ľudia boli schopní vyriešiť sebareflexiu odpradávna. Na začiatku sa voda používala ako azrkadlo. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the zrkadlo for self-reflecting evolved into a bronze zrkadlo. The earlier glass zrkadlos in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass zrkadlo has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the zrkadlo surface is generally narrow and easy to carry; the zrkadlo is mostly used for shaving and shaving, and the zrkadlo surface is only enough to shadow the partial beard.Then, with the passage of time, the silver zrkadlo used by most of us came into being. With the development of technology, the function of the zrkadlo is only self-reflection, it is more intelligent and more humane. More functional, such as: anti-fog, watch time, measure temperature, watch TV, etc. The material of the zrkadlo has also been upgraded from a silver zrkadlo to an "environmental protection zrkadlo". This zrkadlo uses lead-free paint, which is a technical breakthrough of silver zrkadlos. This kind of zrkadlo is called a lead-free and copper-free zrkadlo, also known as an "environmental protection zrkadlo.
