- Lower Temperatures:Conversely, lower temperatures decrease the solubility of the chemicals, causing the solution to become less supersaturated. This results in smaller, more delicate crystals or even a clear solution.
Atmospheric Pressure’s Influence
- Higher Atmospheric Pressure:Higher atmospheric pressure can also influence the formation of crystals. This pressure can cause the solution to become more supersaturated, leading to the formation of larger crystals.
- Lower Atmospheric Pressure:Conversely, lower atmospheric pressure can cause the solution to become less supersaturated, leading to the formation of smaller crystals or a clear solution.
Chemicals Used in Storm Glasses
The specific chemicals used in storm glasses vary, but the most common components include:
- Camphor:This volatile organic compound is known for its characteristic scent and its ability to form crystals readily. It plays a significant role in the formation of the intricate patterns observed in the storm glass.
- Potassium Nitrate:This inorganic salt is highly soluble in water and acts as a stabilizer, helping to prevent the solution from becoming too supersaturated and precipitating out too quickly.
- Alcohol:Ethanol or methanol is used as a solvent, dissolving the other chemicals and creating a homogeneous solution. It also helps to regulate the rate of crystallization.
- Water:Water is the primary solvent, dissolving the other chemicals and creating the liquid medium for the crystals to form.
