sterling silver
The term “Sterling Silver”, in reference to the .925 grade of silver, emerged in England by the 13th century. The term “sterling”, seem to have acquired their meaning over a while, and from several convergent sources. The first mention is that of “sterilensis” in 1078, and by the thirteenth century (the 1200s) the term sterling had appeared.
“Sterling” is believed to come from the Old Norman French esterlin (meaning little star) and Old English stiere (strong, firm, immovable).
Sterling silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals. The minimum millesimal fineness is 925.
Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling the silver is usually alloyed with copper to give strength whilst preserving the ductility of the silver and a high precious metal content.
A sterling silver object that is to be sold commercially is, in many countries, taken to an Assay office for testing of the purity of the metal. The item is then marked, with the Hallmark of that particular nation.
In addition to the hallmarks, silver manufacturers often applied their own specific stamp. For example, the letters “T. and Co.” indicates a piece manufactured by Tiffany and Company. These stamps were as unique as today’s logos, and disputes often arose when one company copied another’s stamp.
The main sources of silver are copper, copper-nickel, gold, lead and lead-zinc ores obtained from Peru, Mexico, China and Australia.
In clothing
Silver is a natural antimicrobial ingredient that has been used for years by professionals in the field of wound healing, mainly because of its scientifically proven antimicrobial efficacy. Silver inhibits the growth of bacteria and fungus. It keeps odour to a minimum and reduces the risk of bacterial and fungal infection. In clothing, the combination of silver and moisture movement (wicking) is the best combination to reduce the harmful effects of prolonged use in active and humid conditions.
