“I always prepare my albuminized paper with the pure white of eggs, which I believe to be preferable to all the cheaper compounds that have been substituted for it. Take any quantity of albumen with double the quantity of water, adding eight grains of chloride of ammonium to each ounce of the mixture. Whip up with a bunch of quills into a froth. The albumen will subside in an hour or two, then filter through a piece of fine linen cloth that has been previously slightly singed over a spirit lamp. Pour the albumen into a flat dish and float the paper for about three or four minutes, having previously folded back one of the corners of the sheet in order to keep it from coming into contact with the albumen. If the paper is pinned up by this unalbuminized corner, it will dry without the least streak or imperfection, but if the albumen conies into contact with the pin. a drip will begin which will end in innumerable streaks. By this precaution much paper may be saved…” … More The albumen process: examples by Thomas J. Nevin ca. 1874
