Examples of crystals grown by different techniques: (a) potassium alum crystals grown by slow evaporation from aqueous solution using seed crystals; (b) a layered alum crystal [chrome alum core (inside) covered by potassium alum shell (outside)]; (c) a copper crystal grown by redox reaction between CuSO4 and Fe; (d) a high-pressure high-temperature modification of BaB4O7 synthesized using the `Discoverer-1500' at 3 GPa, 1273 K; (e) an NaBa12(BO3)7F4 crystal grown from a high-temperature solution by top-seeded solution growth; (f) recrystallization of β-chlorpropamide (prismatic crystal) into γ-chlorpropamide (needles) in a diamond anvil cell at 0.1 GPa in a pentane–iso­pentane (1:1) mixture; (g) lysozyme crystals crystallized by the hanging-drop vapor diffusion antisolvent technique (viewed in polarized light); (h) plastic L-isoleucine single crystals grown inside a glass capillary by layering diffuse antisolvent crystallization (viewed in polarized light); (i) copper chloride dihydrate crystals grown by slow evaporation from a drop (viewed in polarized light). Photographs were taken by Dr E. Losev (a)–(c), (g)–(i), Dr Sci. T. Bekker (d), (e) and Dr Sci. B. Zakharov (f).
