Silicon Nitride Ceramic:
Many pottery pieces and pottery jars of various styles were unearthed from the ruins of the Yin Ruins of the Shang Dynasty. The patterns, symbols, and characters on these pottery were closely related to the oracle bone inscriptions and blue ware of the Yin and Shang era. Pottery was not limited at this time. Containers have a wide range of applications, and can be roughly divided into daily necessities, construction, burial, sacrificial gifts, etc. In the later Qin and Han dynasties, the ancient buildings were mostly made of wood and were not easy to survive. Therefore, some great buildings, such as the Afang Palace in the Qin Dynasty and the Weiyang Palace in the Han Dynasty, could not be fully preserved, but the wadang and Han Dynasty can still be found in the remaining ruins. Relics such as bricks provide a glimpse of the scale of ancient buildings. During the Han Dynasty, glazed pottery replaced copper daily necessities in large quantities, which led to the rapid development of pottery. Due to the mastery of processing skills, pottery ornaments with lively patterns and shapes appeared, which had extremely high artistic value. This is Tao Xiangci Transition bridge. The main achievements of ceramics from the Jin Dynasty to the Southern and Northern Dynasties are mainly reflected in the Yue kiln, which uses celadon as the main decoration and has a high artistic level.
