戊申字의 復元에 관한 實驗的 硏究

Abstract

The purpose of this experimental research is to restore Mu-Sin metal types, recast from Gap-In movable metal types, with the focus on the method of casting. The major findings are as follows:(1) Mu-Sin metal types are copper movable types which Kim Jwamyeong started recasting from Gap-In movable metal types in the Sueo-Cheong in 1668(9th year of Hyeon-Jong's reign) and completed in July 1668 (9th year of Hyeon-Jong's reign).(2) Mu-Sin metal types consist of 66,100 types of large size and 46,600 types of small size, and were transferred from the Sueo-Cheong to the Gyoseo-Gwan in October 1672 (13th year of Hyeon-Jong's reign).(3) The method of sand casting was used to restore Mu-Sin metal types. For this experiment, used were compound metals (110 %) which consist of copper (80%), tin (15%) and lead (15%). The height of those types is about 0.8cm, their backs are the shape of an upside-down ‘U’, and the connections between the faces of types and bridges were experimented with both the one piece and two piece casting method.
