Does fire purify gold?

Depending upon the quantity of gold you are working with and the desired level of purity, the two most common methods for refining gold are the use of high temperature flame and the use of chemicals to refine the gold. Refining with flame is one of the oldest methods of refining metals.

How can you test gold?

The Nitric Acid Test

Gold is a noble metal which means its resistant to corrosion, oxidation and acid. To perform this test, rub your gold on a black stone to leave a visible mark. Then apply nitric acid to the mark. The acid will dissolve any base metals that aren't real gold.

Why is gold tested by fire?

In order for gold to be refined, it must be subjected to an intense fire. This fire is what purifies the gold, because it separates out all of the impurities in the gold, also known as the dross. As the dross is burned away, only the pure gold remains.
