Types of Crystals and Shapes
Crystal growing kits can produce a variety of crystalline structures in different colors and forms:
- Natural formations – Crystalline clusters and rocks with no defined shape. Often made of borax.
- Molded crystals – Distinct shapes like pyramids and prisms cast in plastic molds.
- Geode crystals – Large individual crystals grown on a wire shaped like the inner structure of geodes.
- Dendritic crystals – Crystals with branching tree-like patterns, commonly made of Epsom salt.
- Bismuth crystals – Iridescent stair-stepped cubes formed by bismuth alloys. Need specialized equipment.
- Salt crystals – Cubic crystals made from dissolved salt which is allowed to evaporate.
- Sugar crystals – Formed by allowing a sugar solution to evaporate. Tend to form small gritty crystals.
- Alum crystals – Octahedral crystals made by crystallizing hydrated potassium aluminum sulfate, often dyed.
With the right combination of solutions and conditions, you can grow a wide variety of crystal types at home.
The Crystal Growing Process
Growing crystals is a simple process but requires vigilance and patience as crystals form over hours or days. Here is an overview of the basic crystal growing procedure:
1. Prepare the crystal growing solution.
- Start with a pre-made crystal growing lab solution, or make your own by combining ingredients like borax or Epsom salt with water following kit instructions.
- Add food dye, alum powder, or other additives to color your crystals.
- Carefully pour the solution into the growing container, filling it halfway.
2. Set up the growing chamber.
- Place seed rocks, string substrates, or other platforms in the solution. Position silicon molds if using.
- Cover the container with plastic wrap or lid with holes for ventilation.
3. Let the crystals grow.
- Provide light without excessive heat and avoid vibration or movement.
- Wait patiently from 1-7 days as crystals slowly form in the solution.
4. Harvest and display the crystals.
- When crystals have reached the desired size, remove them from the solution using tweezers.
- Rinse off any excess solution and allow to dry fully.
- Mount the crystals on plastic display trees or stands to showcase their beauty!
With good conditions, you’ll be rewarded with a bumper crop of eye-catching crystals.
Educational Aspects of Crystal Growing
In addition to being fun, crystal growing kits provide a wealth of learning opportunities for students. Here are some of the key educational benefits:
- Introduces chemistry concepts – Explains solutions, chemical bonding, precipitation, geometry, and the nature of crystals.
- Teaches crystal structures – Demonstrates the repeating orderly atomic lattice that makes up crystalline solids.
- Models crystal growth – Shows how crystals emerge and expand from seed crystals in a supersaturated solution.
- Encourages scientific observation – Keeping a growth journal draws attention to changes over time.
- Inspires passion for STEM – Hands-on experiments get kids engaged in science. The dazzling crystals can spark lasting interests.
Crystal growing lends itself well to classroom STEM activities. Teachers can use crystal growing to educate on chemistry, physics, measurement, data analysis, and the scientific method. Students can hypothesize crystal size and shape, then observe and record results. Crystals can even be integrated into engaging science fair projects.
Advanced Crystal Growing Techniques
Once you’ve mastered the basics, try these more advanced crystal growing methods:
- Grow crystals in a Petri dish – Flat and open, Petri dishes allow even crystal growth unobstructed.
- Use paper as a substrate – Strips of paper hung in the solution will sprout crystalline fibers.
- Grow a large single fluorite crystal – Fluorite requires close monitoring to form one large cubic crystal.
- Create light-up crystals – Use glow powder and black lights to make supernatural glowing crystals.
- Grow iridescent rainbow crystals – Bismuth alloys crystallize into stunning iridescent cubes.
These techniques demand patience but produce one-of-a-kind crystalline specimens. Expand your crystal horizons!
Displaying and Decorating Your Crystals
Once grown, crystals can be artfully displayed:
- Mount crystals on their included display trees or stands to show them off.
- Make DIY displays like painting stands with crystals embedded in Mod Podge.
- Hang crystals in windows where sunlight makes them sparkle.
- Glue crystals into the cavities of broken geode halves for an eye-catching interior decorator accent.
- Group crystals of varied shapes and colors together in crystal collections.
The geometric beauty of crystals adds a special decorative touch. Integrate them into your home or office’s décor or give as gifts.

Frequently Asked Questions
What are the fastest growing crystals?
Alum crystals tend to grow the quickest, sometimes reaching full size overnight. Materials like copper sulfate and Epsom salt also grow robust crystals relatively quickly. Slow-growing crystals include borax and bismuth.
How big can crystals grow?
With optimal conditions, crystals can grow quite large, over 12 inches long! But most homegrown crystals max out around 1-3 inches. The size depends on the type, saturation of the solution, and duration of growth.
Can you grow crystals without a kit?
Yes, you can grow crystals without a kit using household materials. All you need is a crystal-growing solution like borax or alum, containers, string, pipettes, and seed crystals. Kits just provide these materials and instructions conveniently.
What is the right temperature for crystal growth?
Ideal crystal growing temperature is around 60-75°F. Avoid extreme heat or cold. Hot temperatures speed evaporation, causing small crystals, while cold slows growth. Maintaining a stable, moderate temperature gives the best crystal results.
Is it safe to let kids handle crystal growing chemicals?
With proper adult supervision, crystal growing is generally safe for kids. Have them wear gloves, goggles, and aprons when handling solutions. Remind them not to touch their eyes or mouth during the process. Follow kit safety instructions closely. Growing crystals can be an educational experience.
