Specifically, how to maintain it, the feeder is mainly made of glass, so it is maintained by the general glass maintenance method:
China glass art has a long history, which was recorded as early as the Shang and Zhou Dynasties. Glass is a valuable work of art, but in recent years, a large number of low-priced "Shui Liu Li" products have appeared in the market. In fact, this is a kind of "imitation glass" product, not a real glass, which consumers should distinguish.
Coloured glaze is known as the first of the five famous vessels in China (gold, silver, jade, colored glaze, ceramics and bronze) and one of the seven treasures of Buddhism. It was basically lost in the Ming Dynasty. However, even the very incomplete crafts in the Ming Dynasty were still protected by grades, and the colored glaze at that time was already very opaque, so it was called medicinal jade. "Ming system" contains: the jewelry awarded to the champion by the emperor is medicinal jade, which is only available for more than four products. After Buddhism spread to China, it was the "Oriental Pure Land" where "the pharmacist's glass shines like Buddha" lived, that is, the pure glass was used as the ground to illuminate the darkness of the three worlds of "heaven and earth". The scripture says, "May I be in the afterlife, and when I get Bodhi, my body will be like glass, and Ming Che inside and outside will be clean and flawless." Therefore, the ancient glazed pottery became the crown of the seven treasures of Buddhism.
The production process of ancient glass is quite complicated. It takes dozens of processes to get from the fire to the water. The production of fine ancient glass is quite time-consuming, and some light production processes take ten or twenty days, and mainly rely on manual production. It is quite difficult to grasp all the links, and the difficulty of grasping the temperature can be said to be half by skill and half by luck.
Maintenance methods of ancient glass:
1, because the hardness of glass is relatively strong, it is equivalent to the strength of nephrite. However, it is also brittle, and the glazed works should not collide or move by friction, so as to avoid surface scratches.
2. Glass works should be kept at room temperature, not hot and cold, and the temperature difference is too large, especially the works should not be heated or cooled locally.
3. The flat surface of glazed works should not be placed directly on the desktop, and it is best to have gaskets or flannel.
4. Glazed glass works can also be wiped with water. If tap water is used, it needs to be left standing for more than 12 hours to keep the surface shiny and clean, and it must not be stained with oil stains and foreign bodies. Avoid contact with strong acidic substances and corrosive gases, such as sulfur gas and chlorine gas, to avoid corrosion.
5. Do not collide or move by friction to avoid surface scratches. Because the hardness of colored glaze is relatively strong, it is equivalent to the strength of nephrite. But it is also brittle, so you can't beat or collide hard.
6, keep the room temperature, real-time temperature difference should not be too big, especially not to heat or cool it.
7. The flat surface is smooth and should not be placed directly on the desktop. It is best to have a gasket.
8. It is advisable to wipe with pure water. If tap water is used, it needs to be left standing for more than 12 hours to keep the surface of the glass shiny and clean, and it must not be stained with oil stains and foreign bodies.
