Beautiful cyan spherulites of recrystallized vitamin C are revealed with striking red concentric ribbons spaced in almost equal intervals. The crystal growth front was selectively altered by Spike Walker during preparation of the specimen. Polarized light and a "Spikeberg" disc were used to illuminate the specimen along with a 12-volt, 100-watt tungsten-halide lamp. The objective was a planapochromat 4x/0.16 NA coupled to a low-power achromatic condenser. The microscope used in the study was a Zeiss Ultraphot III with an automatic 35-millimeter photohead. The film was Fujichrome Velvia. (10x)
