ummm.... let me think about this one...
Heating gold with a lighter will not cause it to burn or catch fire. Gold is a non-combustible metal with a high melting point of 1,943 degrees Fahrenheit, so a regular lighter cannot generate enough heat to melt or ignite it.
When you burn gold with a lighter, the gold will not melt or change its form. Gold is a highly unreactive metal and does not oxidize easily, so it does not burn or get damaged when exposed to a flame from a lighter.
If the gold is not real, it will likely discolor or tarnish when burned with a lighter. Authentic gold does not react to the flame from a lighter, while fake gold may show signs of melting, discoloration, or emit a sulfuric smell.
Fake gold chains often feel lighter than real gold chains because they are typically made of materials that are less dense than gold, such as brass or alloy metals. These materials are lighter in weight compared to solid gold, which is a dense metal. This difference in density is why a fake gold chain might feel lighter.
When you get a lighter and some paper then you set the paper on fire.
One common method to test the purity of gold is by conducting an acid test, where the gold is scratched onto a testing stone and then examined for its reaction to different acid solutions. Another method is X-ray fluorescence (XRF) analysis, where a portable XRF analyzer is used to measure the composition of the gold without damaging the piece. Trusted professionals or jewelers may also use electronic gold testers or fire assay methods to determine the purity of gold.

Gold will not burn, however if the fire is hot it will melt.
