ANTHION-SCHERING The Best Hypo Eliminator.
Five grammes (75 grains) =Anthion= are dissolved in one litre (one quart) of luke-warm distilled water. The solution keeps for at least one month.
_a._ The plate (13 × 18 centimetres--5 × 7 inches) or film, after fixing, is allowed to drain and then washed for about five minutes in a dish with about 600 cubic centimetres (20 fluid ounces) water; it is then again allowed to drain.
_b._ Afterward it is laid in a second dish with 200 c.c. (7 fluid ounces) =Anthion solution=, and again allowed to remain for five minutes with occasional stirring.
_c._ The plate is then once more laid in 600 c.c. (20 fluid ounces) fresh water, exactly according to direction _a_.
_d._ The operations _b_ and _c_ are repeated.
The plate is then =free from fixing soda=. (In order to determine this, proceed as follows:)
To be certain that all the fixing soda is completely destroyed, proceed as follows: Several c.c. (half to one teaspoonful) of the last washing water are poured into a test-tube, and three or four drops silver nitrate solution (1 to 20) added. A white precipitate generally forms. If this gradually acquires a =yellow= tint, fixing soda is still present.
In such a case operations _a_ and _b_ are to be repeated.
The operations are carried out as under A, but instead of one plate five fixed copies (13 × 18 c.c.--5 × 7 inches) are taken, allowed to drain one by one, then laid singly in water (vide _a_), afterward in =Anthion solution= (vide _b_), then again in water (vide _c_), again in =Anthion solution= (vide _d_), and finally in water.
=It is important that the paper prints are frequently separated in the different baths.= If the prints stick together, the solution does not penetrate and cannot act.
