All about Silver

Silver is used extensively in industry as well as in coinage and jewellery and for decorative functions. Mainly because it has excellent conductivity, and thermal properties as well as excellent corrosion resistance and is malleable enough to be worked yet durable enough to be used for the above purposes.

In commercial applications, the special chemical properties, superior thermal and electrical conductivity, high reflectivity, malleability, ductility and good corrosion resistance give it a unique place in industry.

For coinage and jewellery silver is graded in the same way as gold by weight or carats but more usually by degree of purity or fineness. Sterling silver is slightly less than pure silver and has some copper added to improve the hardness.

Silver does tarnish and proprietary silver cleaners are available to remove such tarnish.

40 percent of the worlds silver used is in photography as silver bromide used to develop photographs and only14 percent is actually used in jewellery and coinage. However it is in jewellery and coinage that it is most well known.

Most countries in the world have a silver coinage and whereas once it was in cons of circulation nowadays it is mostly in brilliant uncirculated cons, proof and commemorative coins for presentations and coin collectors.

By this way much effort has gone into creating coins for the sake of their looks and beauty rather than functional and the quality of silver coins has increased as a result markedly over the years.

Now one can get some truly beautiful coins such as the Canadian maple leaf, Chinese Pandas, British Britannias among many others.

So although this is not all about silver it does show that silver is an important part of everyday life and also can ad pleasure in many different ways.
