How Do Crystal Growing Kits Work?
Crystal growing kits work by leveraging the natural process of crystallization through guided experiments to form crystals from solutions. Here is a quick overview of the basic crystal growing process:
Supersaturated Solutions
A supersaturated solution contains a higher concentration of dissolved solute than normal. These unstable solutions encourage solute molecules to come out of the solution and form a solid crystal lattice structure.
Seed Crystals
A seed crystal provides a starting point or foundation for crystal growth. When placed in the supersaturated solution, molecules attach to the seed and crystals start forming.
Crystal Growth
Once the seed is in the supersaturated solution, dissolved particles start arranging themselves into an orderly crystalline structure that matches the seed crystal. This allows the crystal to grow larger over time.
Factors Affecting Growth
Temperature, pressure, pH, vibration, and impurities can impact crystal growth rate and final shape, size, clarity, and color. Kits allow you to experiment with these factors.
So in summary, crystal growing kits provide the materials to create supersaturated solutions and seed crystals to initiate crystal growth which can then be observed over hours, days, or weeks.
Types of Crystal Growing Kits
There are many types of crystal growing kits available for both educational and hobby use. Here are some of the most common varieties:
Starter Kits
Starter kits or basic kits contain the core materials needed to get beginners to grow their first crystals. Great for developing an interest in the hobby.
Advanced Kits
Advanced kits enable the growth of a wider variety of crystal types and include extra equipment for larger, faster crystal growth. Ideal for serious crystal growers.
Science Kits
Science kits are designed specifically for crystal growing classroom experiments and science fair projects. May include curriculum guides.
Specialty Kits
Specialty kits focus on growing specific crystal types like salt, alum, or borax. Some feature Unique shapes or colors.
Geode Kits
Geode kits allow growing crystals on geological specimens like agates or rocks. Great for creating your own crystal-filled geodes.
Electronics Kits
Some kits incorporate LED lights or microscopes into the crystal growth chamber for enhanced observation.
Crystal Growing Instructions
Growing crystals successfully requires careful attention to instructions. Here are some general guidelines to follow with any crystal growing kit:
Step 1: Prepare the Crystallization Chamber
Assemble crystallization containers as directed and place seed crystals (or add a piece of string/toothpick to act as a seed).
Step 2: Make the Supersaturated Solution
Dissolve provided compounds in water following kit instructions to create a supersaturated solution. Stir thoroughly.
Step 3: Pour the Solution into the Chamber
Carefully pour the supersaturated solution into the crystal growth chamber. Fill to the line specified in the instructions.
Step 4: Seal the Chamber
Seal the chamber securely to prevent evaporation which can disrupt crystal formation.
Step 5: Provide Ideal Conditions
Place the chamber in a safe location away from vibrations. Maintain proper temperature as directed.
Step 6: Observe Crystal Growth
Check the chamber daily. Take notes and photos to record the crystal growing process over time.
Step 7: Harvest and Clean Crystals
Once growth slows, carefully remove crystals using tweezers. Rinse in water and allow to fully dry before display.
Be sure to follow all safety guidelines provided with your specific kit and supervise children during use. With good technique, you’ll be growing beautiful crystals in no time!

Solution: Ensure you created a supersaturated solution. Remake the solution and double-check the measurements.
Problem: Crystals are small or grow too slowly
Solution: Increase solution concentration slightly. Verify chamber temperature is ideal for crystal type.
Problem: Crystals have flawed shape or appearance
Solution: Avoid vibration or jostling of the chamber. Filter solution and use distilled water for purity.
Problem: Crystals growing on sides instead of seed
Solution: Be sure the seed crystal is centered and adequate. Scrub sides and restart growth.
Problem: Cloudy solution or precipitate forms
Solution: Stir the solution when mixing to fully dissolve compounds. Filter before pouring if needed.
