Like other engravers, he began by cutting in type-metal, or engraving upon copper.
type-metal is an alloy of lead with antimony and tin, to which occasionally a small quantity of copper or zinc is added.
Having been sent to the casting-room, the types are slightly oiled, and surrounded with a frame of brass or type-metal.
With a result not very different was the application of antimony in the composition of printer's type-metal.
type-metal—a composition mainly of lead and antimony—is poured into this mould, forming a cast of the face of the type.
The type-metal is prepared for immediate use by melting it, as fast as it may be needed, in a small crucible, over a coal fire.
Into this mould the type-metal is poured and the plate formed.
Satisfactory grinding may be carried out by the use of copper or type-metal cones for the preliminary shaping.
It is used in the preparation of alloys with lead and tin for the manufacture of type-metal.
Several attempts have been made to apply other substances than plaster of Paris and type-metal for stereotyping.
