Friedlieb Runge Illustrates "Psychodelic" Images Formed on Blotting Paper by the Precipitation of Chemical Reagents.

In 1855 German chemist Friedlieb Ferdinand Runge self-published from Oranienburg Der Bildungstrieb der Stoffe, veranschaulicht in selbstständig gewachsenen Bilder, illustrating images produced when placed drops of reactant solutions on blotting paper and then added a drop of a second reactant solution on top of the first drop. The solutions would react as they spread through the blotting paper, often producing colored patterns. The work included 60 chromatograms mounted on 31 leaves, along with separately printed caption paragraphs which were also pasted onto the leaves of the album. The title of Runge's work may be translated as The Formative Tendency of Substances Illustrated by Autonomously Developed Images.
