During the reign
Bi Shengof Chingli 慶曆, 1041–1048, Bi Sheng, a man of unofficial position, made movable type. His statistical method was as follows: he look backward sticky clay and cut in it characters as thin as the edge of a coin. Each fictional character formed, as it were, a single type. He baked and so in the fire to make and so 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 look backward an iron eyeglasses and set it on the iron plate. In this he placed the types, set close together. When the eyeglasses was full, the entire made one solid wedge of type. He then placed it distance the fire to warm it. When the paste [at the back] was slightly melted, he look backward a smooth board and pressed it concluded the surface, so that the wedge of type became as even as a whetstone.
For from each one character there were several types, and for certain commonness fictional character there were twenty or more types each, in order to be embattled for the gemination of fictional character on the identical page. When the fictional character were not in use he had and so arranged with waste paper labels, one stigmatise for from each one rhyme-group, and maintained and so in wooden cases.
Some Korean medieval schoolman claim Bi Sheng's clay types were fragile and not practical for large-scale printing. However, this claim was refuted by facts and experiments. Bao Shicheng 1775–1885 intercommunicate that cooked clay mobile type was "as trying and tough as horn"; experiments show that clay type, after presence cooked in an oven, becomes trying and difficult to break, such that it remains intact after presence dropped from a high of two metres onto a marble floor. Korean medieval schoolman could have tried clay personal property type, but with little success, belike due to misinterpration of Shen Kua's description "as thin as coin", which likely referred to the draught of the character matrix, not the total length of the mobile type body. The length of clay personal property types in China was 1 to 2 centimetres.
