Description

Photogravure is a Science Fiction Book. The Book describes that call a rouge polish. If they do not supply it, rouge it yourself with powdered rouge and turpentine, using a ball of absorbent cotton over a large piece of smooth cork. A good way to buy rouge is in the stick; it is more economical. Rub the wet cotton on it and the right quantity is assured. Pits in the copper may be taken out by tapping upon the back with a nail set, using a small piece of polished steel to lay the face of the plate on, and localizing the spot with a pair of calipers. The part raised by the tapping, cut away with the scraper, then rub Pg 26 the spot with Scotch stone and water, then a piece of engraver's charcoal (cut to a pencil point), with machine oil; then burnish with the regular engraver's burnisher and sperm oil, finishing with rouge and refined turpentine. When the plate is well polished, make a strong solution of caustic potash (C. P. ), which comes in sticks, as strong as possible, as long as it does not stain the copper.
