After washing in several changes of water, the proofs may be toned in any toning bath, and then fixed with sulphocyanide of potassium, washing afterwards in the usual manner. ❋ Peter C. Duchochois (N/A)
Frequently the prints appear yellow from formation of the double sulphocyanide of copper, but the color disappears by washing in water. ❋ Peter C. Duchochois (N/A)
As long as FeCl or even Cu2Cl is present, if the print is immersed in the sulphocyanate solution, sulphocyanate of copper is immediately formed on the reduced parts, while on the others the sulphocyanide of copper, formed and dissolved by the sulphocyanide of potassium in excess, becomes decom ‐ posed with water in soluble sulphocyanide of copper and deposited as such on the parts already covered with the salt. ❋ Peter C. Duchochois (N/A)
The author uses a galvanic current for reducing silver residues, consisting of sulphocyanide. ❋ Various (N/A)
The formation of the ammonia produced in the process is probably due to the decomposition of nitrogenous bodies contained in solution in the liquor -- the sulphocyanide, for instance; the nitrogen being given off in the form of ammonia. ❋ Various (N/A)
Dissolve about 8 grammes of ammonic thiocyanate (sulphocyanide) crystals in a liter of water, and adjust to decinormal argentic nitrate solution, by diluting till one volume is exactly equal to a volume of the latter. ❋ Various (N/A)
On the whole, the bath that has given the best results is one containing, in addition to gold, a small quantity of hypo and a considerable quantity of sulphocyanide of ammonium. ❋ Various (N/A)
They are decidedly more pleasing than those of 7 or 8, but are not as good as the best by the sulphocyanide bath. ❋ Various (N/A)
It is very inferior to that in No. 3, the color less pleasant, and the appearance generally as if the details of the lights had been bleached by the large quantity either of hypo or of sulphocyanide of potassium. ❋ Various (N/A)
The general lesson taught by Clark's experiments is that the sulphocyanide bath gives better results than any other. ❋ Various (N/A)
Opposite to this description of formula there are no prints, but the following is written: "These prints were completely destroyed, the sulphocyanide of potassium (probably) dissolving off the gelatine." ❋ Various (N/A)
Any of the ordinary alkaline toning baths may be used, but they all give results inferior to those got by the sulphocyanide bath. ❋ Various (N/A)
The sulphocyanide of potassium, KCsy, is prepared by fusing ferrocyanide of potassium, deprived of its water of crystallization, intimately mixed with half its weight of sulphur and 17 parts of carbonate of potassa. ❋ Various (N/A)
Herapath, 1858, saturated paper during or after its manufacture with a solution of a ferrocyanide, a ferriccyanide, or sulphocyanide of potassium, sodium, or ammonium. ❋ Unknown (1904)
The blood-red solution of sulphocyanide of iron is in itself not stable: when the red solution of this salt is so exposed to the sun, that the rays pass through the glass jar containing it, it is rendered colourless, but the colour is retained or restored when the rays pass directly from the air into the fluid; so that when a properly diluted solution is placed in a cylindrical glass vessel in direct sunshine, it loses colour in the morning till about eleven in the forenoon, when the rays beginning to fall upon the surface exposed to the air, gradually restore the colour, which attains its maximum about two o'clock. ❋ George Field (N/A)
The knee-cap bone, or patella, of a sheep, known locally as the "cramp-bone," is worn in Northamptonshire for a like purpose; also the application of a gold wedding ring (first wetted with saliva, an ingredient in the holy salve of the Saxons), to a stye threatened in an eyelid is often found to disperse the swelling; but in this case [516] it may be, that a sulphocyanide of gold is formed with the spittle, which promotes the cure by absorption. ❋ William Thomas Fernie (N/A)
a small quantity of a solution of potassium sulphocyanide for the purpose of obtaining a red tint, which is more visible and disappears also under the influence of light in proportion to the decomposition of the perchloride. ❋ Peter C. Duchochois (N/A)
"sulphocyanide of allyl," which is almost identical with the essential oil of White Mustard. ❋ William Thomas Fernie (N/A)
