Beeswax casting, finished movable type pieces

Movables type pieces are finished when types attached to the tips of a metal tree are separated and typefaces rubbed against a fine grindstone after the mold is removed. Finished movable type pieces are separated individually and stored in a type case for convenience. During the Joseon dynasty, between 100,000 and 300,000 movable type pieces were typically made when making a font. The greater the number of type pieces, the greater the efficiency in printing because many printing blocksformes can be typeset at the same time.
