Stained Glass Work: A text-book for students and workers in glass. Christopher Whall

from a distance. It is useless to try and learn these things from written directions; you must make them your own, as precious secrets, by much practice and much experiment, though it will save you years of both to learn under a good master.

      But this question of distance is a most important thing, and we must enlarge upon it a little and try to make it quite clear.

      Glass-painting is not like any other painting in this respect.

      Let us say that you see an oil-painting—a portrait—at the end of the large room in some big Exhibition. You stand near it and say, "Yes, that is the King" (or the Commander-in-Chief), "a good likeness; however do they do those patent-leather boots?" But after you have been down one side of the room and turn round at the other end to yawn, you catch sight of it again; and still you say, "Yes, it's a good likeness," and "really those boots are very clever!" But if it had been your own painting on glass, and sitting at your easel you had at last said, "Yes,—now it's like the drawing—that's the expression," you could by no means safely count on being able to say the same at all distances. You may say it at ten feet off, at twenty, and yet at thirty the shades may all gather together into black patches; the drawing of the eyelids and eyes may vanish in one general black blot, the half-tones on the cheeks may all go to nothing. These actual things, for instance, will be the result if the cheeks are stippled or scrubbed, and the shade round the eyes left as a film—ever so slight a film will do it. Seen near, you see the drawing through the film; but as you go away the light will come pouring stronger and stronger through the brush or stipple marks on the cheeks, until all films will cut out against it like black spots, altering the whole expression past recognition.
