Will gold coins melt in a house fire?

Gold melts at a much colder temperature, about 2000 degrees Fahrenheit, but that's enough to survive most household fires. Platinum jewelry is the most expensive, so it's good that the melting point of the metal is just above 3,200 degrees Fahrenheit. Sapphire and ruby also have extremely high melting points. No, because gold is not very reactive, it doesn't burn in a house fire.

But it could melt, depending on the temperatures reached. Gold is an excellent electrical conductor and is malleable, making it useful for applications in jewelry and dentistry. Gold does not react with oxygen under extreme heat, so, perhaps as expected, it does not react with oxygen at room temperature with water present either. This makes it easy to see gold solely from the point of view that it is an incredible financial asset, but the truth is that it also possesses remarkable physical characteristics.

Its most common use is as a precious metal for coins and jewelry, but it is also used in infrared shielding, gold lead, dentistry, electronics and even in medicines. Gold melts at a temperature of 2000 degrees Fahrenheit (or 1064 degrees Celsius), which means that if you have a fire in your house, it could melt, but it won't catch fire or get lost. However, once it starts to heat up, gold is a conductor of heat and that means it will heat up fairly quickly. It is soft as metals and can be easily shaped into almost any shape, especially since it is also ductile (a property that makes gold suitable for use in the electronics industry).

You can delay the tarnishing of cheap metals mixed with gold by cleaning the piece after wearing it and avoiding colonies, hairspray, etc. That's why all the gold extracted from the earth continues to melt, re-melted and used again and again. This is, in fact, the easiest way to purify gold and was used to purify gold in the Middle Ages, when there were no more complex processes. If I were storing gold at home, I would look for a safe hidden in the ground, placed in concrete in the basement.

Yes, gold has a very low specific heat capacity and that means that it heats up very quickly compared to other metals. At present, gold cannot be destroyed at the molecular level with any natural substance on Earth. While it's true that some gold jewelry turns green over time, it's not because gold reacts. In addition, given the costs of gold, most people will never have the opportunity to consume enough gold to be poisoned by it.
