What makes a crystal grow bigger?

A crystal grows bigger when the conditions for its formation are favorable, allowing more atoms or molecules to join its structure. This typically occurs when there is a supersaturation of the solution, meaning there are more dissolved substances than can remain in solution. Additionally, a stable environment with consistent temperature and pressure promotes the orderly arrangement of particles, leading to larger crystal sizes. Factors like purity of the material and the availability of space can also influence growth.
