Crystal is a rare mineral primarily composed of silicon dioxide. When a high-temperature saturated solution is cooled and moisture evaporates, it turns into a supersaturated solution. The crystalline molecules released from this supersaturated solution are continuously adsorbed onto the crystal particles, gradually growing larger to form the beautiful "crystal" structure.

The small experiment we saw today can quickly reveal crystals that would normally take millions of years to form, so let’s step into the magical world of these wonderous crystals together.

【Principle of Crystal Growth】: A saturated crystal powder solution, upon cooling and with the evaporation of water, turns into an oversaturated solution. The crystalline molecules released from this oversaturated solution continuously combine together, accumulating and growing on larger crystal particles, eventually forming beautiful “crystals” with irregular shapes.

Science; Chemistry; Crystallization; Saturation

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

Days turn into months, depending on the desired size

The specific duration depends on the desired size.

The time period ranges from a few days to several months.

?Chrome alum (chromium alum or potassium chromium sulfate dodecahydrate) potassium chromate/sulfate alum

?water Water

?alum (ammonium aluminum sulfate) (optional – added to lighten the color of the crystals) potassium aluminum sulfate/alum

?transparent glass jar

?spoon or stirring rod Spoon or stirring rod

1. Prepare a chromium alum solution by mixing 60 g of potassium chromium sulfate with 100 ml of water.

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

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

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

5. Cover the container loosely with a coffee filter or paper towel. At room temperature (~2–5°C), the crystal can be grown through slow evaporation, either for as short 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; the darker the solution color, the darker the final crystal color will be.

4. Very small crystals will grow in this solution; at that point, a thin rope can be used to hang the small crystals from the remaining solution.

5. Cover the container slightly with a paper towel and store it at room temperature, waiting for the crystal to form.

Tips

Tips

1. It is better to wear gloves when preparing the chromium alum solution, as it may cause skin irritation.

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

1. It is advisable to wear gloves when handling chromium alum solution, as contact with the skin may cause discomfort.

2. Although the final solution is dark blue-green, the crystals that form will be purple, so there’s no need to worry.

Please check that the circuit is unobstructed and all components are intact before assembly, as well as ensure all contact points are properly aligned. During assembly, be careful not to let glue get on your clothes or skin. Keep the components out of reach for younger siblings to prevent them from accidentally swallowing them! Do not play with them on your head, as the model may fall and hurt you!
