Hand mould

From Wikipedia, the free encyclopedia

A Hand mould is a two-part mould used for casting small metal objects that could be operated by hand. In particular, it refers to a system for casting movable type, pioneered by Johannes Gutenberg, which was widely used in the early era of printing in Europe (15th-16th century).

In this method, the type was made by punching a letter-shaped cavity in a matrix made of some soft metal (typically copper). Then this matrix would be held in the lower part of the mould, the upper part would close on it, and molten type metal would be poured into the cavity. Using the hand mould, the printer could quickly make any additional type he might need.
