《Changing a chemical element into other one》

There used to be dubious people who were called the alchemists in the Middle Ages.😃

They told kings and the aristocracy that they could change cheap lead into expensive gold.The alchemists stayed at the castle for days,but they ran away without any success finally.💨

It was impossible to change a metal into gold,or no one couldn't turn a chemical element into other one with the technology in those days.😚

In a word,the alchemists used to be swindles then.😚

《The alchemists who were all make-believe》

There is a knife of which only tip changed into gold with the alchemy in a museum,but it's just that the tip was covered with gold plate 金メッキ.It's a compound metal 合金 made from gold and mercury 水銀.😜

The compound metal is a simple technology.Statues of Buddha were also covered with the gold plate in the Tenpyo era.😃

However,the compound metal is covering metal with the gold.It doesn't mean changing the metal into gold.😃
