Chytré koupelnové zrcadlo: vývoj a historie zrcadel

Lidé dokázali vyřešit sebereflexi od starověku. Na začátku byla voda používána jako azrcadlo. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the zrcadlo for self-reflecting evolved into a bronze zrcadlo. The earlier glass zrcadlos in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass zrcadlo has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the zrcadlo surface is generally narrow and easy to carry; the zrcadlo is mostly used for shaving and shaving, and the zrcadlo surface is only enough to shadow the partial beard.Then, with the passage of time, the silver zrcadlo used by most of us came into being. With the development of technology, the function of the zrcadlo 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 zrcadlo has also been upgraded from a silver zrcadlo to an "environmental protection zrcadlo". This zrcadlo uses lead-free paint, which is a technical breakthrough of silver zrcadlos. This kind of zrcadlo is called a lead-free and copper-free zrcadlo, also known as an "environmental protection zrcadlo.
