Gold is one of the many precious metals found on the periodic table of elements with an atomic number of 79.
Gold has been – and continues to be – used for many purposes from making coins to making jewelry.
Pure gold, in its original form, is in nugget or grain consistency. It can’t be used for much in those shapes. In order to get gold into the shapes needed it must be melted and special equipment must be used. The gold itself is melted and boiled in containers called crucibles, and the materials that are used for crucibles and molds or casts must be able to withstand the temperatures that are necessary to melt and boil gold.
The temperature required to melt gold is 1,948 degrees Fahrenheit. To make gold stronger, because it is naturally too soft to be used practically, other alloy metals like copper, zinc and silver are added during the melting process. The boiling point of gold occurs at 5,173 degrees Fahrenheit.
