Metal type

Movable metal printing type
Movable printing types allowed for much more flexible processes than hand copying or block printing. It was invented in 1041 by Bi Sheng in China. Sheng used clay type, which broke easily, but Wang Zhen later carved more durable type from wood. Eventually, invention of movable type metal printing press came about in 1234 during the Goryeo Dynasty of Korea by Chwe Yun-Ui. Examples of this metal type are on display in the Asian Reading Room of the Library of Congress in Washington, D.C. The oldest extant movable metal print book is the Jikji, printed in Korea in 1377.
