Silver crystals are grown from a chemical solution. You can watch the crystals grow under a microscope or you can allow the crystals to grow for a longer time to use them in projects or for display.

Bismuth crystals may be the prettiest crystals you can grow! The metal crystals form when bismuth is melted and allowed to cool. The rainbow effect results from natural oxidation on the surface of the crystals.

You can grow tin crystals using a simple displacement reaction. This is a quick and easy crystal growing project, producing crystals in one hour (viewed live using magnification) to overnight (larger crystals). You can even grow a structure that resembles a metal hedgehog.
