To Stereotype Zinc Etchings.—

For this work a very wet mould, free from creases, is recommended. Those who use readymade flong should let it lie twenty minutes in cold water, carefully dry between blotting-paper, and then beat in. Those who prepare their own matrices will mix the matrix-powder or chalk with cold water to the consistency of milk, and spread thickly on the paper, beating continually but lightly with a soft brush. All zinc-etchings must be thoroughly washed with paraffin before stereotyping, and also woodcuts which are to be stereotyped. Old woodcuts and etchings which are covered with hard dried ink must be laid down in paraffin for at least half-an-hour, otherwise the stereotype will not be a success.
