Ways to Test the Purity of Gold

Different methods are adopted to test the purity of gold. Karat is the measurement used for measuring the purity of gold. Pure gold is usually known as 24 karat gold. Before the invention of gold testing machine, the purity of gold was tested using porcelain, glass and magnet. The use of porcelain to test the purity of the metal-gold included scratching the sample metal on unglazed porcelain, if the color of the streak is yellow, it is pure gold.

Similarly the use of glass to check the purity of gold included scratching the sample metal on a piece of glass, since gold is known to be softer than glass, it should not leave any mark on the glass when scratched.

Magnets were also considered as the ancient Metal Testing in Chennai. This simple test involves holding the sample metal near to the magnet, if it is pure gold, the magnet fails to attract it. All these tests mentioned above are different kinds of initial tests which do not prove the content of gold present or the exact amount. Since the gold testing machine was unavailable in those days, most of the people resorted to such methods which have become obsolete today.

Acid testing is another method to test the purity of gold. But it is known to cause damage to the precious metal so it is not used by most of the professionals though it is quiet cheap compared to other methods of testing the purity of gold.
