WebCrystals form in nature when molecules gather to stabilize when liquid starts to cool and harden. This process is called crystallization and can happen when magma hardens or when water evaporates from a natural mixture too. Many crystals start small but as more atoms join and create a uniform and repetitive pattern, the crystal grows. Web7 de abr. de 2024 · 3: Crystallization.

The solution is placed in an ice-water bath to lower the temperature even further, and allow more crystals to form. At this point, most crystals should already have formed. The crystals are filtered and air-dried.
