Movable type is the system of printing and typography that uses movable components to reproduce the elements of a document (usually individual letters or punctuation).
The world's first known movable-type system for printing was created in China around 1040 A.D. by Pi Sheng (990–1051) during the Song Dynasty; following that, the first metal movable-type system for printing was made in Korea during the Goryeo Dynasty (around 1230). This led to the printing of the Jikji in 1377—today the oldest extant movable metal print book. The diffusion of both movable-type systems was, however, limited: They were expensive, and required an enormous amount of labour involved in manipulating the thousands of ceramic tablets, or in the case of Korea, metal tablets required for scripts based on the Chinese writing system, which have thousands of characters.
Around 1450, Johannes Gutenberg invented the printing press and independently developed a movable type system in Europe, along with innovations in casting the type based on a matrix and hand mould. The more limited number of characters needed for European languages was an important factor. Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimony—the same components still used today.
