Definitions

This invention relates to a process and composition for the production of mirror bright alloy gold.
Among the objects of the invention is to provide a process and composition for electroplating a pale yellow gold alloy layer of any desired thickness onto a basis metal.
One phase of this invention is based on the discovery that an antimony compound can be added to a gold cyanide electroplating bath to produce a pale yellow gold alloy deposit under certain conditions.
an antimony compound can be added to a gold cyanide electroplating bath to produce a pale yellow gold alloy deposit under certain conditions.
an antimony compound can be added to a gold cyanide electrolyte solution to produce an electrodeposit having a dull gray or black appearance depending on the conditions of operation and the concentrations added.
the condition under which a pale yellow deposit from such a combination is obtained according to the present invention is that a proportion of a polyhydric alcohol be added to the electroplating hath.
Suitable antimony compounds which may be added to the bath include antimonyoxide, antimony tartrate, etc.
Potassium gold cyanide (67% Au) 0.5 to 4 oz. (troy).
