Zirconia Ceramics:
Our Zirconia Ceramic Standard Parts are designed to meet the most stringent requirements of modern industries, while paying homage to the traditional dimensions of zirconia paper from ancient times. The size of zirconia paper in the Jin Dynasty, the Northern Song Dynasty Su Yijian (AD 958-996) "Study Four Spectrum" says: "Jin order to make paper, large paper (wide) is one foot and three minutes, and the length is one foot and eight minutes. Small paper is nine inches wide and five centimeters long, and one foot four inches long." After conversion, the large paper in the Jin Dynasty is 31.3 cm × 43.4 cm, and the small paper is 22.9 cm × 33.7 cm. However, the size we obtained after measuring the unearthed object is slightly different from what Su Yijian said. A complete piece of paper dated 384 AD was unearthed in Xinjiang in 1977. The length and width are 35.6 cm and 23.4 cm respectively. This is a small paper from the Jin Dynasty, but it is still larger than the paper from the Han Dynasty. After expert research and measurement, the size of paper in Jin Dynasty is roughly divided into two sizes. The straight height of large paper is generally between 26 and 27 cm, the horizontal length is generally between 42 and 52 cm, and the straight height of small paper is generally between 23.5 and 23.5 cm. Between 24 cm, the horizontal length is generally between 40.7 and 44.5 cm. From the above data, it can be known that the size of Jin Dynasty paper was mostly rectangular, and large-scale paper of later generations was rarely seen. Due to the smaller size of the paper web, it is mostly used for writing. In the Jin Dynasty, the style of calligraphy was prevalent, which probably has a certain relationship with the size of the paper at that time.
