The malleability of Silver
The malleability of silver make it a versatile semi precious metal to work with. Many fine items of silver jewellery can be hand crafted to immense detail. An illustration of this property is displayed by the incredible detail of this silver bowl outlining the entire history of Cambodia. The bowl is on display in our Plymouth shop. The bowl shows that the uses of silver need not be confined to jewellery.
The Chemical Composition of Silver jewellery
In order to add a little strength and rigidity, copper is added to pure silver to produce sterling silver which is the key ingredient of our jewellery. The proportion of silver to copper is 92.5% to 7.5% copper. Some items, particularly the gemstone set rings are coated with a layer of rhodium which gives the silver an extra shine reducing the amount of polishing. There are no other metals involved except for very small amounts of iron solder used for welding joints on the larger pieces. No zinc, nickel or other allergy sensitive metals are used.
More about silver jewellery
One of the problems in manufacturing silver jewellery is fire scale or as it sometimes known fire stain. This is a red stain that you can see once copper is mixed with the silver. Coppers melting point is 100C above Silver, so once the temperature during soldering etc is close to silver's melting point the oxygen reacts with the copper to form cuprous oxide and then cupric oxide. Another problem is Porosity in which tiny air bubbles are trapped in the silver as it cools down. To prevent these issues, the temperature is controlled to precise degrees and maintained with a consistency that prevents the formation of air bubbles or fire stain.
The obvious method of identifying an item of jewellery or ornament is by its markings, stamp or hallmark. The silver bowl is marked by its maker which often also indicates the purity of the metal used as well as its age. To enable the purity of to be determined there are a range of various silver tests.
