These are portraits in one color on porcelain, glass or any hard

material that has first been coated with gelatin and then photographed

on. First treat the whole surface with pumice stone as directed for the

bromide paper, afterwards go over it with the crayon and cotton. Then

put in the cloud effect in the background, and clean off the lights in

the face, hair, and clothes with the eraser; next put in the

with the peerless stump; then with a solution of India ink

darken the stronger shadows throughout the portrait--in the eyes, nose,

mouth and eyebrows, and finally in the hair. Finish the face with the

No. 0 crayon and the 4 H. Faber's lead pencil according to directions

given for finishing bromide enlargements. The Faber pencil is used

almost exclusively throughout the face. Very nice effects of strong

light can be made on porcelain by scraping through the gelatin surface

with the knife. This process is specially adapted to making pictures of

smaller size, say 10x12, or 11x14 inches, as it produces a very soft

and delicate effect.
