Is genuine gold really not afraid of being tested by fire?

The article "Is Real Gold Really Not Afraid of Fire?" cites the legend that gold utensils and jewelry melted into gold ingots after a fire in an ancient mansion and remained intact, to explain the saying "Real gold is not afraid of fire". It explains that gold is highly chemically inert and not easily reacted with other substances. Although its melting point is only 1064℃, it melts at high temperatures with little volatilization, almost no loss of mass, and unchanged color. It also introduces platinum (commonly known as white gold), which is more resistant to high temperatures and has more stable chemical properties, and meets the standard of "Real gold is not afraid of fire".

Is genuine gold really not afraid of being tested by fire?

According to legend, there was once a grand mansion that caught fire, and all the furniture, money, and clothes were destroyed. However, among the ruins after the fire, people found some gold ingots. Where did they come from? It turned out that the family had once been wealthy, with many gold utensils and jewelry. Although they were melted and deformed by the high temperature and flames, they weren't completely destroyed. Instead, they merged into gold ingots, which still shone brightly. Therefore, since ancient times, people have regarded gold as a precious treasure and bestowed upon it the reputation of "real gold fears no fire".

Gold also melts at temperatures above 1064℃. In fact, real gold isn't completely fireproof. Its melting point is 1064℃, which isn't particularly high among metals. Ancient people had long mastered the processing techniques of gold. Gold can escape the "clutches" of fire mainly because it is extremely inert and chemically stable. The commonly known "gold" is actually gold, a precious metal element. Its most notable feature is its stable chemical properties, making it highly resistant to chemical reactions with other substances. Whether at room temperature or high temperatures, gold doesn't react with oxygen, so we don't see gold rusting. Gold is also resistant to most acids and alkalis, making it particularly corrosion-resistant compared to metals like copper and iron. Even highly oxidizing nitric acid can't dissolve gold, and only a solution of concentrated nitric acid and concentrated hydrochloric acid (volume ratio of 1:3) can dissolve it. Due to its chemical stability, even at high temperatures, gold may change its "form" but not its "essence". After cooling, its surface still shines brightly! If the temperature is further raised to exceed gold's melting point, gold will melt, but even after melting, it evaporates very little. After cooling, the gold obtained still has the same color and luster as before, with almost no loss in quality.

By the standard of "real gold fears no fire", there is another type of "real gold" that is even more remarkable than gold, which is commonly known as platinum. In fact, platinum isn't an element of gold, but another metal element called platinum. Platinum has a silvery-white surface and is more resistant to high temperatures than gold. Even when heated to 1750℃, it still doesn't discolor or melt, fully demonstrating the qualities of "real gold". No wonder people are accustomed to calling platinum white gold. Platinum is also very stable chemically. In chemical laboratories, platinum crucibles are often used to hold chemicals and conduct experiments at high temperatures. Chemicals melt and react in platinum crucibles, but platinum itself remains unchanged, unaffected by high temperatures or other chemicals, fully demonstrating its high-temperature resistance and super stability.
