Pure Gold
What is Pure Gold? Pure gold is a dense, soft, shiny and the most moldable and ductile pure metal that is known. Gold has a very attractive look to it and is bright yellow in color. Pure Gold is the basis for the standard in gold.
Gold does react with amalgam alloys, which is the dissolving of gold into mercury. Nitric acid dissolves silver and base metals, therefore gold does not dissolve in nitric acid. The gold standard test is used to determine the real value and since Nitric acid has been used to confirm the presence of gold in certain items, this is where they get the acid test or gold standard test from.
In summary, a U.S. recession does not have any negative implications for the gold price thanks to the unique drivers of gold demand and supply. The only element of gold demand that could be affected by a recession is investment demand, but that in turn will also depend to a large part on the actual ‘type’ of recession. So far, the brewing recession has been positive for gold investment purposes as it has been accompanied by a rise in inflation and a falling dollar, which has boosted the demand for gold as a dollar and inflation hedge.
The proportion and type of added metals can change the colour and hardness of the alloys. For example, a reddish alloy has a higher proportion of copper while a silvery alloy has a higher proportion of silver. In making “white gold”, no copper is used. White gold is still a form of karat gold, but the presence of silver and nickel or palladium creates a completely silvery appearance.
