STAINLESS SILVER
After stainless steel, we find, comes stainless silver. A new way of covering silver with an invisible film has been found bv two Cambridge metallurgists. The result of the experiments of Br G. J. Thomas and Dr L. E. Price is that the fortunate people born with silver spoons in their mouths will never find them tarnishing. The secret of stainless steel is that of covering it with a film of metal combined with oxygen The new alloy film for silver consists of a very small amount of aluminium treated in an atmoshpere of hydrogen and water vapour When it emerges from the treatment the alloy is covered with an oxide of aluminium, very hard but so transparent as to be invisible. If it will resist wear and tear the housemaid who has to clean the silver will rise up and bless it, for no plate powder will ever be required.
