What Exactly Are Crystal Growing Kits?

Crystal growing kits are products that allow you to easily grow crystals at home. They contain all the materials you need, like seed crystals, crystal powder, and a growing chamber. By combining the ingredients and manipulating factors like temperature, you can grow gorgeous, custom-colored crystals in a variety of shapes and sizes.

These science toys have educational benefits that allow kids to learn about chemistry, physics, biology, and more in a hands-on way. They also provide a fun creative outlet and quality family time activity.

While crystal growing was once only done in labs, it is now an engaging hobby anyone can enjoy at home with the right tools.

A Brief History of Crystal Growing Kits

The earliest crystal growing kits appeared in the 1940s and 50s as educational chemistry sets for students. They were produced by companies like Porter Chemical and allowed growing simple crystals like alum and copper sulfate.

In the 1960s and 70s, more advanced crystal growing kits entered the mainstream consumer market. Notable examples include the Atomic Energy Lab which grew nuclear reactor fuel salt crystals, and the Visible Crystals Set which grew brightly colored crystals.

Over the next decades, crystal growing kits continued improving to allow the growth of larger and more complex crystals of minerals like amethyst and quartz.

In the 2000s, major manufacturers like 4M and National Geographic began producing crystal growing kits aimed at educational STEM learning for children.

Today, crystal growing kits use modern materials to simplify the process and grow brilliant custom-colored crystals at home easily.

The Science Behind Growing Crystals

The crystals grown with kits form through a natural process known as crystallization which occurs in two main phases:

Nucleation

This begins when solute molecules suspended in a solvent start aggregating into organized crystal structures called nuclei.

Supersaturation (an excess of solute), temperature changes, and the presence of seed crystals can trigger nucleation.

Growth

Stable nuclei attract free solute molecules that attach in an orderly way, causing the crystal structure to grow larger over time.

Factors like temperature, pressure, and purity of the solution impact the growth process.

Understanding these fundamental concepts allows tweaking factors like temperature and concentration to grow quality crystals reliably.

How to Use a Crystal Growing Kit

Follow this simple step-by-step guide to grow stunning crystals successfully:

Materials Needed

  • Crystal growing kit
  • Distilled water
  • Measuring cup
  • Wooden spoon for mixing

Optional:

  • Food coloring (for custom colors)
  • Isopropyl alcohol (to re-grow crystals)

Preparation

  1. Read kit instructions fully.
  2. Wash hands and the work area thoroughly.
  3. Assemble materials and tools.

Mixing the Solution

  1. Boil distilled water. Let cool slightly.
  2. Pour boiled water into the growing chamber(s).
  3. Add the powder slowly, mixing to dissolve.
  4. Optional: Add drops of food coloring and mix.

Seeding the Crystals

  1. Use tweezers to place seed rocks in the solution.
  2. Space seeds evenly, keeping them fully submerged.

Growing the Crystals

  1. Cover the chamber to prevent evaporation.
  2. Place in a warm area out of direct sunlight.
  3. Allow crystals to grow undisturbed for 1-3 weeks.

Harvesting Crystals

  1. Remove crystals gently using tweezers.
  2. Rinse uncolored crystals in lukewarm water.
  3. Display crystals on an included stand or in a glass jar.

Tips for Growing Quality Crystals

Follow these tips to improve crystal size, clarity, and color:

  • Maintain proper temperature around 70-75°F.
  • Avoid light exposure to prevent algae growth.
  • Gently stir the solution once a day.
  • Position seeds evenly apart near the bottom.
  • Use distilled water for purity.

Be patient – some crystals may take 2-3 weeks to fully form!
