A solution of pure Ascorbic acid (Vitamin C) was evaporated on a microscope slide to form crystals. By viewing these crystals using polarised light microscopy, amazing and interesting colours and patterns are seen. This is due to the crystals forming regular arrays and interfering with the light path to give the colours seen (no colours were changed using Photoshop).
