Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object briefly into a solution containing silver ions.
The levels are “G1” (mild), “G2” (moderate) and “G3” (harsh), reported as equivalent months or years. For equivalent months, for copper, the thickness of the deposits in Angstrom units is divided by 300 for G1, 1000 for G2 and 2000 for G3. For silver, the thickness in Angstrom units is divided by 200, 1000 and 2000, respectively.
The company arose out of the Oneida Community, which was established in Oneida, New York, in 1848. [4] The Oneida Association (later Oneida Community) was founded by a small group of Christian Perfectionists led by John Humphrey Noyes, Jonathan Burt, George W. Cragin, Harriet A.Noyes, George W. Noyes, John L. Skinner and a few others. [5]
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
OSP Pair of table salts, the interiors gilded to prevent corrosion. 'Bleeding' of the copper can be seen on the rims. Old Sheffield Plate (or OSP) is the name generally given to the material developed by Thomas Boulsover in the 1740s, a fusion of copper and sterling silver [1] which could be made into a range of items normally made in solid silver.

Plated ware refers to articles chiefly intended for tableware consisting of a base metal or alloy covered by one of the precious metals, with the object of giving them the appearance of gold or silver. [1] Historically, the standard amount of precious metal used was an ounce of silver per square foot of surface area (2.8cL per 930 cm 2).
One such example is the formation of silver chloride on silver wire in chloride solutions to make silver/silver-chloride (AgCl) electrodes. Electropolishing, a process that uses an electric current to selectively remove the outermost layer from the surface of a metal object, is the reverse of the process of electroplating. [1]
Silver is rarely used for its electrical conductivity, due to its high cost, although an exception is in radio-frequency engineering, particularly at VHF and higher frequencies where silver plating improves electrical conductivity because those currents tend to flow on the surface of conductors rather than through the interior.
