When you take silver mercury
Which is also called quicksilver
And add some crystal cinnabar
Which is also called vermilion
Then heat the mixture with sulfur to 455 degrees Fahrenheit【235°C】
You get red mercury or mercury 2 sulfide
It is also called the Red King
Because of the brilliant red pigment of the vermilion
And on account of its amazing properties
Red mercury is the quintessence of alchemy
And the highest achievement of metallurgy
It is the philosophers stone
Because it will turn base metals into gold
Also, cinnibar already IS mercury(II) sulfide. And highly toxic.
