An alchemist shapes a clay golem beside copper furnaces and a homunculus in a jar, with whales drifting past a sunken city beyond.

Variable Mercury

Alchemy, Essence

A reddish powder; a single grain set in wax and dropped into a large batch of molten lead or mercury turns it into pure gold almost instantly.

Also called The Philosopher's Stone

From the book

Also known as the Philosopher's Stone, this essence takes the form of a dram (60 grains) of reddish powder. A single grain, pressed into a drop of yellow wax and dropped into 100 lbs. of molten lead or mercury, changes the whole amount into the purest gold almost at once. The alchemist will need a very large crucible to do this.

Like every essence, it is drawn out with a quarter fluid dram of alchahest from 12 drams of its base substance, using an aludel, an athanor and a full laboratory over at least two weeks; success rests on a save vs Will, and a failed attempt must be repeated from the start.
