Crystal, a rare mineral, is mainly composed of silicon dioxide. It is formed by using a high-temperature saturated solution, cooling it, and then adding water to cause evaporation, which will result in an oversaturated solution. The crystalline molecules released from the oversaturated solution will continuously be adsorbed onto the crystal, and the crystalline molecules will gradually grow, forming the beautiful 'crystal' shape.

Today, the small experiment we are witnessing can quickly reveal crystals that would normally take millions of years to form, allowing us to enter a world of magical and colorful crystals in a short period of time. Let's step into this magical world of crystals together.

The growth principle of crystal: Saturated crystal powder solution, after cooling, becomes an oversaturated solution as a result of water evaporation. The crystalline molecules released from the oversaturated solution continuously combine together, accumulating and growing continuously on some larger crystal grains, eventually forming beautiful and irregular-shaped 'crystals'.

Science; Chemistry; Crystallization; Saturation

Growth crystals in STEAM education correspond to the chemical science, specifically applied to the knowledge of crystallization and saturation.

days to months, depending on the desired size

The specific duration depends on the size desired.

The time span varies from a few days to several months.

Chrome alum (chromium alum or potassium chromium sulfate dodecahydrate) 硫酸铬钾/铬明矾

Water

Potassium Alum (Potassium Aluminum Sulfate) (Optional - added to lighten the color of the crystals)

Transparent glass jar

Spoon or stirring rod

1. Mix 60 grams of potassium chromium sulfate with 100 milliliters of water to make a chromium alum solution.

2. In a separate container, prepare a saturated solution of ordinary alum by stirring alum into warm water until it will no longer dissolve.

3. Mix the two solutions in any proportion that you like. The more deeply colored solutions will produce darker crystals, but it will also be harder to monitor crystal growth.

4. Use this solution to grow a seed crystal, then tie it to a string and suspend the crystal in the remaining mixture.

5. Loosely cover the container with a coffee filter or paper towel. At room temperature (~25°C), the crystal can be grown via slow evaporation for as little time as a few days or as long as a few months.

1. Dissolve 60 grams of chromium alum in 100 milliliters of water.

2. Prepare a saturated solution of alum in another container (i.e., add alum to warm water and stir until it no longer dissolves).

3. Mix the two solutions in any ratio, and the deeper the solution color, the deeper the final crystal color will be;

4. In this solution, very small crystals will grow, and at this point, you can tie a thin string to hang the small crystals in the remaining solution.

5. Cover the container slightly with a tissue paper, store it at room temperature, and wait for the crystal to grow.

Tips

Tips

1. It's better to wear gloves when making chromium alum solution since it may cause skin irritation.

2. Please note that the chrome alum solution is a dark blue-green, but the crystals are purple!

1. When handling chromium alum solution, it is best to wear gloves, as contact with the skin may cause discomfort.

The solution after 2. is deep blue-green, but the crystals that grow will be purple. Don't worry!

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
