Mercury Principle, Fermentation and Plant Spirits
The mercury principle represents the spirit of a material and is extracted through fermentation processes. Anaerobic fermentation produces alcohol or volatile mercury, while aerobic fermentation, such as making kombucha or vinegar, produces fixed mercury in the form of organic acids. These distillates are historically referred to as "spirits" due to their alchemical classification.
