Another process for salting paper is:
| Chloride of Ammonium | 3 | grs. |
| Chloride of Sodium | 3 | grs. |
| Water | 2 | oz. |
Apply this solution with a brush, or float the paper on the bath. To sensitize, take 60 grs. of nitrate of silver and 1 oz. of water. Add ammonia-water, drop by drop, till 25 drops have been used. The solution at first turns muddy, but continue dropping the ammonia till it clears. If it does not clear after the 25 drops have been added clear by filtering. Sensitize as per former directions.
This paper is very easily prepared, is inexpensive, and gives fine delicate prints. Do not print much deeper than is desired for the finished print. One may use a toning and fixing bath combined, or a separate toning and fixing bath may be used.
One can sensitize a strip at the head of a letter or a corner of a visiting-card; and print the same as any paper.
The paper can be bought ready salted, but it is not always fresh. It is very little trouble to salt paper and to sensitize it, and the cost is much less than when paper is bought ready prepared. The plain paper should be used within two or three days after sensitizing with the silver, but the salted paper keeps well, and may be sensitized as needed.
Mark the sensitized paper on the wrong side lightly, as it is hard to distinguish the sensitive side. When dry these prints are so flat and the paper is so thin that they make nice book illustrations.
