C3 - The rotating chemical spiral

C3 - The rotating chemical spiral

As shown here, in aqueous solutions, chemical reactions may develop spiral-shaped patterns, as the chemical waves in the Belousov—Zhabotinskii reaction show. C3, with its relief structure is based on a chemical spiral which rotates around a center and at the same time expands two-dimensionally within a thin layer of solution. The distance between two wave-fronts is about 1 mm. Precise measurement of the center of rotation - located at the inner side of the spiral tip (C4) - and analysis of lines of equal concentration (C5) reveal that the geometry of the wave develops according to the rules of an Archimedian spiral.
