Shore, 1840, used a solution of nitrate of nickel in one compartment of battery, and weak sulphuric acid and zinc in the other, for deposition of nickel.
An alloy of nickel and tin made by melting under borax and glass was used for coating iron plates by Richardson and Braithwaite, 1840.
The alloy was applied melted, as in tinning iron.
Alfred Smee made an electro deposition of nickel in 1841.

Bottger, in the Journal fur Praktische Chemie, Vol XXX. p. 267, 1843, says that among all the salts of nickel the ammonio sulphate of protoxyde of nickel is especially useful in plating brass and copper, and is much superior to cyanide nickel of potash, as recommended by Ruolz.
He proceeds at some length to state the effectiveness of the battery in producing a deposit of nickel on copper in half an hour, which would deflect the needle, and preser
bing, hose, etc., on the principle of Tatham's American machine for making lead pipe, patented in 1841.
In 1846, Mr. James Reynolds, of New York, invented a machine for covering iron wire with indid between the rollers, and discharged on to a straight mandrel, smaller than the bore.
