These colours are enough to fill you with PURE joy.
As the impurities are removed from the surface of the molten bismuth the non-oxidised metal underneath reflects a beautiful array of psychedelic colours.
Heart-shaped and circular patters turn from red to blue to gold, almost as if the sun is rising and setting on its surface.
The video was shot by bismuth crystal creator Madiel Langedefeu.
Madiel said: “Bismuth is element 83 on periodic table, and it melts at 271 Celsius.
“My deep pot contains 65 kg bismuth crystals. When it is heated using my 1200W electric stove, it takes 3 hours to melt.
“When the surface layer melts and comes into contact with the air it oxidises and forms a thin film, which reflects light in a really beautiful way.
“As more of the bismuth oxidises and the layer becomes thicker the colour gradually changes.
“The more it oxidises the slower the rate and therefore the colour change becomes.
“I remove the oxide layer on the metal’s surface as it contains impurities, and I need a pure metal to create bismuth crystals.
“Once I turn the stove off, the temperature of the bismuth slowly decreases and crystals start to from below the surface, and when they grew big enough I extract them.
“By removing the impurities the crystals reach 99.99 per cent purity.
“A lot of people seem to enjoy watching the videos are fascinated to watch the metal as it changes.”
Madiel ships his crystals to be sold to a store in Baccarat, France.
