Tertia Intensive: Four Days August 26 – 29th


The Tertia classs examines the works on minerals and metals, which some consider to be the pinnacle of alchemical works.  The class spans four days and covers the theories on metallic alchemy and also provides practical examination of both the wet and dry methods.  We spend a whole day on the acetate path and a whole day on antimony.  We also contrast these methods with alchemical works of India (rasashastra).


Robert Bartlett is the only teacher in the world who teaches on these subjects in such a detailed, practical format.


Thursday through Sunday, starts at 10am on Thursday, ends on Sunday at 6pm.


Refunds if cancelled within 3 days of your order. No refunds after, though credit can be given for a future class after three days minus a 10% fee.
