Crystal growing is the hobby of producing crystals of various compounds. Crystals may be grown for other purposes, such as X-ray crystallography, but the amateur chemist is often interested in the aesthetic appeal.
Recommended compounds
Beginner
- Iodine can be sublimed in a closed vessel, and it will form deposits of purple to black crystals in the vessel when cooled. These crystals are small and fragile, but highly presentable. (orthorhombic, Cmca)
- Phthalic anhydride forms wiry, needle-like crystals when the vapor is allowed to condense. Phthalic acid can be used, and this will form phthalic anhydride in the process. Thicker crystals can be grown from a melt. (orthorhombic, Pna21)
- Salicylic acid crystals form rapidly when a methanolic solution is diluted with water. These crystals can grow to impressive sizes. (monoclinic, P21/c)
- Sucrose can be used to grow rock candy. (monoclinic, P21)
Intermediate
- Terbium acetate crystals are colorless but fluoresce bright green under ultraviolet light. (triclinic, P-1)
