Abstract

512,516. Tarnish-resistant silver surfaces. GOLDSMITHS OF THE CITY OF LONDON, WARDENS & COMMONALTY OF THE MYSTERY OF, PRICE, L. E., and THOMAS, G. J. Feb. 9, 1938, Nos. 4087 and 21021. [Class 82 (ii)] A tarnish-resistant silver surface is prepared by alloying silver with beryllium, aluminium or silicon, and oxidizing the surface of the alloy by heating in a non-oxidizing gas such as hydrogen containing a small amount of a gaseous oxidizing medium such as steam. Copper, zinc, cadmium or tin may be present in the alloy.
