Does gold jewelry melt in a house fire?
Because gold melts at around 1800 degrees Fahrenheit (depending on the karatage), and most house fires burn at less than 1200 degrees, it is rare that gold jewelry will melt beyond repair in the event of a house fire. This means that, when everything else is lost, jewelry can often be salvaged.
Does real gold turn black?
Because gold is a relatively soft metal, most jewelers mix it with other metals such as silver, copper and nickel to increase its hardness and durability.

How do I tell if gold is real?
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.
