Maintenance of tile roof
Guwadang is a historical relic, most of which were unearthed. Unearthed tiles show that sometimes there are attachments such as soil, which are very strong. Some accessories even wrapped the whole tile. When cleaning these accessories, you should be especially careful not to damage the surface of the tile. When collecting ceramic tiles in the south, we should also pay attention to moisture prevention. If the tiles are damp, there will be many mildew spots, which will cause the tiles to change color due to corrosion, which will affect the beauty of the collection and damage the cultural relics.
Although ceramic tile is an accessory of architecture, it embodies and reflects the thoughts, politics and national beliefs in a specific historical stage, and is the carrier of a national culture. Soil rust (copper rust) attached to the surface of ceramic tiles is more valuable because it reflects a historical precipitation. The soil rust on the tile surface can be compared with the color of bronzes and the blood and soil immersion of jade, revealing the beauty of simplicity and obscurity, from which we can feel the slow rolling of the wheel of history. Once the tile loses its rust layer? Coat? Exposing a new crop will be boring. So take care of it. Go into battle lightly, avoid collision, wipe less, and pay special attention to not rubbing a lot casually.
The ancients had no photographic technology, so they could only stick rubbings on tiles and spread them out with rubbings. This is due to technical limitations and is the only way.
Today, with the popularization of photography technology, the role of photos can not be ignored, and they can replace some rubbings. However, although rubbings can't fully reflect the nuances of tile-shaped ornamentation, they can grasp the overall charm of tile-shaped ornamentation, which is concise and summarized, or black or vermilion, and also has a quaint artistic conception, which is very quaint and lovely.
In addition, the blank space around the rubbings can also be used for inscription or writing some related words. Therefore, Wadang rubbings are still valued by collectors today, which is irreplaceable by photos.
So photos can't replace rubbings. However, whether it is rubbing or patting, red or black, it can't be too broad. Ceramic tiles are argillaceous pottery, not as hard, delicate and fragile as stones and jade, and can be cleaned after extension. Ceramic tiles are easy to absorb water and the patina is easy to fall off.
In addition, paper is easy to leak, and more extension will make tiles appear? Bao Gong face? Or? Guan Gong's face? His face was badly damaged by it. If it is emphasized that the effect of rubbings must be extended, it is better to extend less, and rubbings should be masters. However, neither collection nor people's collection should be driven by commercial interests, but should be extensive. Especially those orphans and treasures, cannot be expanded.
Appreciation of Wadang
Ceramic tiles, like other arts, are also a reflection of certain socio-economic ideology. With the development of social economy and the improvement of people's appreciation of architectural art, there is a development process from low to high, from rough to exquisite, from simple to complex.
For example, most of the characters in the Han dynasty are tiles of seal script; During the three kingdoms and the Jin dynasty, there were sawtooth patterns on the tile edge; When follwed was popular? Four Gods Wadang? That is, the tiles are painted with images of dragons, white tigers, rosefinch and Xuanwu, representing east, south, west and north; In the late Eastern Jin Dynasty, tiles with black polished surfaces began to appear, and one end of the eaves tiles began to thicken, and decorative patterns were embossed. Dripping water? The origin of; To the Tang Dynasty? Diwa? Universal application.
Morning? Dripping water? The included angle with the tile body is generally a right angle, which increases to more than 100 degrees in the later period. This is scientific, which shows that the tile in ancient China has the function of combining decoration with practicality. The Han dynasty is a prosperous era, and the word tile in the Han dynasty is a microcosm of it, such as? Changle weiyang? 、? Eternal life is infinite? 、? Long live the Millennium? 、? Korea and the world? 、? Longevity 、? Endless 100 million years? And so on, these characters are mostly small seal characters, with symmetrical and harmonious arrangement and exquisite layout, which can be comparable to a good seal character.
In a word, the shapes of the tile are varied, which are not only the art of combining painting, craft and sculpture, but also the art of combining practicality and art, and have played a icing on the cake in some ancient buildings. It not only gives people elegant, magnificent and beautiful artistic enjoyment, but also helps us to date in archaeology. At the same time, it is also a precious material for studying China's calligraphy, seal cutting and painting, which is of great significance for studying China's ancient politics and economy.
