No no no, not with all the magical properties.

It's just a fun game about the myths origin.

Supposes you're an medieval alchemist who stumbled upon some interesting chemicals, and you bragged about it, which later got mythologized to be the philosopher stone. What would it be?

​

Rules of the Game:

The material must be available to an ancient alchemist, with processing techniques of the time.

It must contain the 4 stages of the philosopher stone in terms of color: Black -> White -> Yellow/Gold -> Red.

Hidden steps allowed: Suppose the alchemist wanted to prevent others from making it, thus omitting some steps. But the end product must be red.

The end product must contain some relatively interesting chemical property, ideally somewhat resembles the mythological ones, like reacting with metal to produce different looking metals, hallucinogenic etc.

​

What do you think the philosopher stone might be? And what are the chemicals that correspond to each step?
