Abstract
The nature of bright metal surfaces and the methods available for their production are discussed. It is shown that the production of a bright surface (other than by mechanical working or by rupture at cleavage planes) involves the deposition or removal of surface atoms in a random manner. Methods by which random electrodeposition of atoms giving bright plating can be achieved are discussed. A detailed mechanism of the action of addition agents is described, in which it is suggested that two main categories of such agents can be distinguished. Suggestions for practical advances based on the general theory are made.
