Detection of gold by burning

How to test the authenticity of gold with a lighter?

Detecting gold by burning is one of the very simple ways to detect gold from change at home. The detection of gold by burning is in such a way that you first set fire to the gold and try to burn your gold. If your gold is real, it will brighten with the flame, but it won't actually catch fire or burn. If your gold piece starts to smoke or darken, you probably have fake gold and you've easily tested the gold standard at home.

It is interesting to know that real gold does not burn and darken under heat and simply melts; That is why it can be molded and made into different shapes without losing its luster and beautiful golden yellow color.

On the other hand, other metals such as copper, iron and brass change color and become darker when exposed to flame. If your item is only gold plated, the gold plating will melt and you will see a darker metal underneath.
