ກະຈົກຫ້ອງນ້ ຳ ສະຫມາດ: ການພັດທະນາແລະປະຫວັດສາດຂອງກະຈົກ

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