An ingot, in short, is produced by heating the metal substance beyond its point of fusion . In this way, the liquid metal can be dumped inside a mold. Once it cools, you can manipulate the ingot in question.
Cooling begins in the surface layer; thats why he center It tends to retain a higher temperature than the edges. This makes solidification derive in the development of a crystal structure .
With the ingot already produced, it is possible to develop others processes . Extrusion or casting, for example, allows the generation of other types of metal objects.
Usually the ingots look like pyramid with rectangular base and truncated tip, or parallelepiped . This makes it easier to stowage.
The gold bullion In this framework, they constitute one of the most common ways to store this chemical element . Institutions such as central banks and other entities usually have gold bullion reserves of 400 troy ounces (equivalent to 12.4 kilograms), with a purity of at least 99.5%.
The price of a gold bullion varies constantly. This value is determined from the game of supply and demand in the market .
