Crystal change principle explanation: The change of crystallization in the bottle is mainly due to the fact that the solubility of the camphor in the solution in ethanol changes with temperature. Potassium nitrate, ammonium chloride, and water are used to control continuous nucleation during rapid crystal growth. When the temperature changes, the crystal of camphor precipitates, and the speed of temperature change will affect the growth size and structure of the crystal. These factors add up to a beautiful variety of crystal types inside the bottle.

Manual measurement, please allow slight errors on size.
