ammonio

• “If it be desired the ammonio-nitrate method may be used instead of the boiling one, although in my hands it does not give such sensitiveness.”

  Scientific American Supplement, No. 303, October 22, 1881

• “This salt has also been incorporated with milled soap in a dry state in conjunction with ammonio-mercuric chloride, [beta] - naphthol, methyl salicylate, and eucalyptol.”

  The Handbook of Soap Manufacture

• “Pictures produced by the ammonio-nitrate are most uncertain.”

• “With acetate of lead, protochloride of tin, ammonio-sulphate of copper, and acetate of alumina, it yields a fine blue colour with a tint of violet, said not to be affected by air or light, and therefore recommended for dyeing.”

  Field's Chromatography or Treatise on Colours and Pigments as Used by Artists

• “Lay the paper on this, and then hang it up to dry, and excite with ammonio-nitrate containing seventy grains of nitrate of silver to one ounce of water.”

• “-- The best formula for this process, of many that I have tried, is that furnished by Prof. C.H. Kain, of Camden, N.J., in which the quantity of ammonio-citrate of iron is exactly double that of the red prussiate of potash, and the solutions strong.”

• “The unused developer produces the best crystals for the purpose, and the pure ammonio-oxalate is vastly better than either.”

  Scientific American Supplement, No. 483, April 4, 1885

• “Dissolve six grains of red prussiate of potash in one drm. of distilled water; in another drm. of distilled water dissolve twelve grains of ammonio-citrate of iron.”

  Scientific American Supplement, No. 483, April 4, 1885

• “It may be developed in a great many ways: by a solution of silver nitrate at 2 or 3 per cent. of water acidified slightly by an organic acid — citric acid, for example — or a diluted solution of ammonio-nitrate of silver, which most likely constitutes the best developer; the image is black and consists of metallic silver and ferric oxide, with formation of silver oxalate, which dissolve in the ammonia.”

  Photographic Reproduction Processes

• “Paper is to be washed with a moderately concentrated solution of ammonio-citrate of iron and dried.”
