Generally speaking, real gold is not afraid of fire, and gold will not change color with fire. Although the melting point of gold is not high, the chemical stability of gold is very high. It is not easy to have a chemical reaction with other substances. You don't have to worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. So the gold necklace becomes dark after burning with fire, or it may be because gold is impure. Because there is no 100%purity gold in essence. So if you are more worried that the gold necklace is fake, you can take the gold necklace to the professional institution to detect it. Low -purity golden fire will also change color change.
It is fake when the gold is burning. Gold is composed of monocular chemical elements. Its texture is very soft and color is golden. The effect is very prominent in terms of corrosion resistance. Both physical characteristics and stability are very good. It will not easily occur with other substances. The reaction will not occur at the high temperature state, so if it is burned with fire, it will not turn black if it is real gold. This is why the ancient saying is not afraid of fire refining.
