Seed crystals

Seed crystals are small particles or crystals used to initiate the formation of larger crystals in materials like salts, minerals, or metals. When a solution cools or evaporates, it can become supersaturated, meaning there's more dissolved material than can remain in solution. Introducing a seed crystal provides a surface for the dissolved material to attach to, promoting the growth of larger crystals around it. This process is important in various fields, including chemistry, geology, and even food production, as it helps control the size and quality of the resulting crystals.
