Gold Testing Lab in Chennai

Gold Testing Lab In Chennai  One must know how to avoid buying false gold products.  When you see 24K, it means that it’s pure gold. However, a 18K gold item means that it’s only 18 parts real gold and six parts from other element. Jewelry experts and experienced investor specialists realize how to test if gold is genuine. This is because gold has its one of a kind physical and chemical properties. There are over seven tests. Gold is a long lasting metal because it is:  Resistant to oxidation - it doesn’t smudge or rust.  Non-magnetic – still wondering “Is gold magnetic or not?” – Sure It isn't.  Extreme thermal and electrical conductive – also corrosion- resistant. Thus it makes gold indispensable in electronics.  Gets dissolved only by nitro-hydrochloric acid – a mix of 75% nitric acid and 25% hydrochloric acid which has a yellow-orange color.  Malleable – press into very thin sheets, 10x thinner than paper. The sheets are then used for infrared reflectivity (by evaporating the sheets over the glass) and used as fillings for teeth, etc.  Ductile – able to be drawn out into a thin wire. Useful as industrial solder, jet engine fabrication, etc.  Sectile – it’s a relatively soft metal. To combat its weakness, it must combine with other elements like silver, nickel, copper or platinum.
