Sensitive crystallisation

From Anthroposophy

Sensitive crystallization or copper chloride (bio)crystallization (german: Kupferchloridkristallisation) is a method to study the quality of substance and life under influence of the etheric formative forces. It is a picture forming method developed by Ehrenfried Pfeiffer (together with Erika Sabarth), and worked out by pioneers Alla Selawry (1913-1992) and Hans Krüger (1898-1988).

Recent research has been done by a.o. Jens-Otto Andersen and Jean-Georges Barth.
