Depiction of Sedziwój performing a transmutation for Sigismund III by Jan Matejko, 1867. Projection was the ultimate goal of Western alchemy.Once the philosopher's stone or powder of projection had been created, the process of projection would be used to transmute a lesser substance into a higher form; often lead into gold.

[3] While alchemists often understood chrysopoeia as a metaphor for a mystical or religious process, some practitioners adopted a literal interpretation and tried to make gold through physical experimentation.
Ternary plot of different colors of Ag–Au–Cu alloys [1]. Colored gold is the name given to any gold that has been treated using techniques to change its natural color.
