HOW IS SILVER MADE?
Fine silver has a brilliant white lustre. It can be beaten, stretched and shaped into all kinds of forms and intricate patterns. That’s why the art of silversmithing was known to many ancient civilisations. The Minoans worked beautiful silver pieces. The Aztec nobles of Mexico adorned themselves from head to toe in elaborate silver jewellery, reflecting their religious culture and incorporating semi-precious stones. The Ancient Egyptians went to the trouble of importing silver, using it to symbolise religious power and combining it with gorgeous lapis lazuli, turquoise or carmelian.
Silver can be found in a pure form, or it can be extracted from compounds such as Argentine (silver and sulphur) or from copper ore or lead ore. Extraction sometimes involves heating the ore in a furnace to convert the sulphides to sulphates and then using a chemical process to derive metallic silver.
It has been known for centuries that combining silver into alloys with other metals can make a beautiful, durable material. The term ‘sterling silver’ is derived from the silver alloy coinage minted by the ‘Easterlings’, Germans who traded with the early English kingdoms. In more recent centuries sterling silver was the material of choice for making fine cutlery and tableware. In England and later in the United States, the accredited standard for sterling silver was set at a minimum 92.5% silver with usually 7.5% copper. In jewellery sterling silver is plated with a fine layer of pure silver.
APART FROM JEWELLERY WHAT IS SILVER USED FOR?
Because silver conducts electricity easily, it’s used for electrical wiring and components. Silver paints are used for making printed circuits. Silver’s anti-microbial properties make it useful in medical dressings. The compound, silver nitrate, is used extensively in photography. Silver iodide has been used for seeding clouds to produce rain.
HOW DOES SILVER COMPARE TO PLATINUM?
Coming back down to Earth, silver needs the occasional clean, but can soon be restored to its dazzling brilliance. By contrast, platinum has a grey-white lustre and is tarnish-free. In jewellery, platinum tends to be used in a purer form than silver. It is strong and hard-wearing, making it ideal for setting diamonds and other gemstones.
