Movable type printing

Bi Sheng was a commoner and his ancestry and details were not recorded. He was recorded only in the Writings Beside the Meng Creek (夢溪筆談 Mengxi Bitan, or Dream Pool Essays) by Chinese scholar, official, and polymath scientist Shen Kuo (沈括) (1031–1095). The Dream Pool Essays ( Pinyin: Meng Xi Bi Tan; Wade-Giles: Meng Ch'i Pi T'an Chinese: 夢溪筆談／梦溪笔谈 Shen Kuo or Shen Kua ( (1031&ndash1095 style name Cunzhong and pseudonym Mengqi Weng, was a Polymathic Chinese Writings Beside the Meng Creek, however, gave detailed and sufficient description on the technical details of Bi Sheng's invention of movable type:

During the reign of Chingli, [1041-1048] Bi Sheng, a man of unofficial position, made movable type. His method was as follows: he took sticky clay and cut in it characters as thin as the edge of a coin. Each character formed, as it were, a single type. He baked them in the fire to make them hard. He had previously prepared an iron plate and he had covered his plate with a mixture of pine resin, wax, and paper ashes. When he wished to print, he took an iron frame and set it on the iron plate. In this he placed the types, set close together. When the frame was full, the whole made one solid block of type. He then placed it near the fire to warm it. When the paste [at the back] was slightly melted, he took a smooth board and pressed it over the surface, so that the block of type became as even as a whetstone. ^[1]

For each character there were several types, and for certain common characters there were twenty or more types each, in order to be prepared for the repetition of characters on the same page. When the characters were not in use he had them arranged with paper labels, one label for each rhyme-group, and kept them in wooden cases. ^[1]

However, Bi Sheng's fragile clay types were not practical for large-scale printing. ^[2] The government official Wang Zhen (fl. This article is about Wang Zhen agronomist and inventor For other historical figures with this name see Wang Zhen (disambiguation. 1290-1333 AD) improved Bi Sheng's fragile clay types by creating movable types out of wood, as his process increased the speed of typesetting as well. Afterwards, metal movable type printing was developed in Korea and in China by 1490 with the bronze metal movable type of the wealthy printer Hua Sui (1439-1513). Bronze is any of a broad range of Copper alloys, usually with Tin as the main additive but sometimes with other elements such as Phosphorus Hua Sui ( Traditional Chinese: 華燧 Simplified Chinese:华燧 Hanyu Pinyin: Huá Suì (1439-1513 AD was a Chinese Scholar and
