A solution of imidazole (a chemical which is very close in structure to the amino acid Histidine) 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).
Blank inside so perfect for any occasion.
