Introduction to melting point of gold:
Gold is a chemical element with the assigned symbol Au in Chemistry. This symbol is derived from Latin word “aurum” meaning "shining dawn". It has an atomic number of 79. It developed an association with richness from the earliest times in human civilization and a mention of its usage for coinage, jewelry, and other arts can be found since the beginnings of recorded history. It has always fascinated mankind and has been the real motive behind many wars in the medieval times as a highly sought-after precious metal

Natural Occurrences of gold
Gold is found in nature as nuggets or grains in rocks, in veins and in alluvial deposits. It is soft, shiny and the most malleable and ductile pure metal known. With a density of 19.3 gm/cm3, it is one of the densest metals. It is also the least reactive among all metals and does not oxidize or corrode in air or water in the normal course.
Pure gold is chemically least reactive of all the metals and dissolves only in aqua regia (a mixture of HCl and HNO3) to form chloroauric acid but is not affected by the individual acids. It dissolves when added to mercury to form amalgam alloys but without chemical reaction. Its insolubility in nitric acid has been long used in gold refining and to confirm the presence of gold in mixtures and objects.
These properties make it quite handy to carry, move around or store for a long time. A relatively low melting point of gold makes it ideal for casting. These qualities and its use for coinage appear to have been instrumental in making it a symbol of wealth.

Melting Point of Gold
Melting point of gold depends on the presence of impurities as it is seldom used in its pure form except as stored wealth or bullion. Traditionally, its purity is measured in Karats with 24 K (Karats) showing the 100% purity, and each lesser number denoting how many parts equivalent of pure gold are present in 24 parts. 18 K gold is the purity most often found in ornaments, which is 18 parts of gold with 6 parts of copper and traces of other impurities.
18 K gold has a melting point of 1675 degrees Fahrenheit or 912.78 degrees Celsius. Addition of further copper reduces it and 14 K gold has a melting point of 1550 degrees Fahrenheit or 843.33 degrees Celsius.
In its purest form Gold has a Melting point of 1337.33 degrees Kelvin equivalent to 1064.18 degrees Celsius or 1947.52 degrees Fahrenheit.
