The half finished elixir i recall reading about on levity.com
but since they changed the format of the site i have been unable to find this reference. I do not remember what author of what text only
that he went on about famous alchemists being fools thinking they had the philosophers stone when in reality they only had the half finished elixir.
Also described as a heavy citrine oil. If there's anyone out there who knows what i am talking about or it jogs anyone's memory let me know.
