Tiles (such as tiles) in Han Dynasty are the roof tiles of ancient Chinese buildings, commonly known as tile heads. There is a self-named "Dang" in the word "Wadang", such as "Shi Jing Dang Yu"; Say "tile", such as "Dusikongwa" and "Changshui Tunwa"; There are also "Shang", such as "Changling Dongshang" and "Yong", such as "Shu Tomb Yong" and so on. The predecessors said that the tile comb is placed on the eaves, and the tiles are of mutual value, while the tile head tube tile is only the bottom of many tiles, which has the function of blocking and shielding.
Mr. Chen Zhi quoted the sentence of "cutting gold for ornament" in Ban Gu's Fu on Xi Du, and interpreted "Jun" as "rafter headdress". According to the position of the tile, it is located at the end of the tile and above the rafters, which are used to cover the wood at the eaves. So the name "tile" probably comes from its position and function. Ceramic tiles are generally argillaceous gray pottery, and clay is generally yellow loam, with pure yellow color, good viscosity and little sand and gravel.
The invention of Wa Dang and Wa Dang is based on highly developed pottery-making technology, which is produced to meet the needs of more mature civil structure buildings. At present, the earliest tiles and tiles found in China appeared under the ruins of palace buildings in the middle and late Western Zhou Dynasty. Therefore, the appearance of the Western Zhou Wadang reflects the precocity, development and uniqueness of China's ancient architectural technology, which is another original creation among many inventions in ancient China.
The use of ceramic tiles can not only strengthen building components, protect eaves and rafters from wind and rain erosion, and prolong building life, but also achieve the artistic effect of decorating and beautifying buildings with its wonderful and vivid patterns and characters.
It is not only a practical product, but also a work of art, and the content of social ideology it contains has unconsciously become the propaganda material for rulers to publicize their way of governing the country. On the magnificent large-scale building, with exquisite ceramic tiles, it constitutes an architectural model with China characteristics.
