For this workshop we collaborated with the artist Emauela Ascari to do chromatographies of polluted soils. It is method to study the formative forces in inorganic and organic substances, mostly used in biodynamic farming (and in a more sophisticated way in laboratories as a technique for the separation of a mixture) to analyse the quality and the vitality of soils. With the Capillary Dynamolysis technique, patterns are produced on thin layer chromatographic paper and evaluated as a fingerprint of the sample as a whole.
