Cinnabar is actually a sulfide, with high levels of mercury. It's alchemical properties are completely different.
Alchemy is the nonsensical idea that it's possible to turn lesser metals like lead into gold, - which is chemically impossible, within bounds of reason - producing a universal solvent, - which actually might be impossible - and producing an elixir of life. The last of those was usually based around mercury; one need not speculate why attempts to produce it were unsuccessful.
Both of which do not exist as people claim to understand them. A flashlight might seem magical to a caveman.

They don't exist as most humans think they do. Some people understand the true nature of magic and spirit.
Its more likely some unknown physical laws that science has yet to understand. Likely something to do with dark energy and dark matter.
That's an interesting theory. Completely wrong, but still interesting. Either way, let's just agree to disagree on this particular subject.
Again, flashlights may appear magical to a caveman. Theres probably entities out there on a higher plane or a completely different universe that have harnessed it in the same way we've harnessed electricity.
No, that is not the definition of alchemy. You're thinking of either magic or shamanism. Or witchcraft. Not however alchemy.
Shamanism is the use of chemical or spiritual (usually chemical) techniques to reach an altered state of consciousness and allows for communication with with spiritual beings. (Or yelling at toasters. Most cases of shamanism that I've studied were little more than an all natural acid trip.) Magic is a general term that covers many fields of arcane study, including shamanism and alchemy.
I'm posting this again. Your arguing with me will do nothing to change the dictionary definition of the word you are using.
Technically speaking, the concept concerning any metal, although historically most attempted it with lead since it's weight was most similar to gold.
