Question: How are crystals made?

Martin Ward answered on 5 Feb 2021:

we can do lots of things to make crystals, some of them are very easy too. One example is cooling a sample down until crystals form, this is what happens when you make ice cubes in your freezer. we can also cause them to form by making a solution and allowing some of the liquid to evaporate away, eventually the concentration will get high enough to cause crystals to form. In our work we use more complicated ways with lasers and high pressures
