Two Techniques for Growing Crystals at Home

Rada is a finance consultant, translator and writer. As an explorer of life, she likes to share her findings with other people.


Crystals are impressive with their perfectly aligned facets and angles that make them sparkle. They are found everywhere. We walk on crystals. We build from crystals. We work with crystals in factories. We grow crystals in laboratories. We eat crystals and heal with them.

Crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.

There are several ways to grow a crystal, but in this article, we will teach the most popular method. The process itself isn't complex, but it requires patience and precision.

Magic is not just for the entertainment, but to inspire people to be creative enough with their lives.

Technique 1

Supplies NeededAmountTips

Potassium Aluminum Sulfate

100 g

You can buy sulfates at any pharmacy.

Potassium Chromium Sulfate

12 g

For getting a magic violet color



Preferably to take a glass

Fishing line


You will catch your luck... a goldfish.


400 ml



  1. First, you should make a mixture of different sulfates. Take 100 grams of potassium aluminium sulfate and 12 grams of potassium chromium sulfate, and put in a glass.
  2. Then, pour 400 ml of hot water into the glass, and stir the mixture until it's completely dissolved.
  3. Leave the solution for 24 hours. Crystals should fall to the bottom of the mixture.
  4. Transfer the solution from one glass to the other. At the bottom of the glass, you will see beautiful crystal formations.

5. Now, put the mass on a plate and choose the biggest one of the crystals. It will serve as a seed; we will use it for growing a large crystal.

6. The solution left should be filtered and freed from any remaining crystal dust.

7. Attach a seed to a fishing line, tie it to a stick, and place into a glass with solution. Be sure no seeds are touching the bottom of the glass.


8. Now, just be patient and wait until our crystal grows up.

9. Water will gradually evaporate, extra sulfates will form into our crystal hanging from a line.

10. A crystal will begin forming the right geometric shape—a crystal matrix of the chemical. For sulfates, it is octahedral.


During growth, you will see new crystal formations at the bottom of the glass and on a line; you have to remove these odd crystals. Or you can save it for the next time (it will be used as a solution).

While growing, it's necessary to avoid fluctuations in temperature and solution contamination.

Two months after, you can get a crystal similar to that on the picture. Take your finished crystal out of water, wipe it with a paper towel, and cover with colorless varnish.


Crystals are living beings at the beginning of creation.

Technique 2

Tools needed

Sodium Chloride (Salt)

Small pan

A glass




  1. Put some water in a pot and begin to boil without allowing it to come to a full boil. Add salt to the pot in small amounts, stirring constantly. You should not add the next portion of salt until the preceding portion is completely dissolved. Concentration of the solution should be so strong that grains of salt can't dissolve anymore.
  2. Now, leave the solution for a day. The principle of growing is the same as in the previous way.

You may notice that a crystal grows faster with the rapid cooling of the salt solution. In this situation, a salt crystal will form its irregular geometric shape. In contrast, crystals forming with gradual reduction of temperature will take more time to grow, but you'll be surprised by their perfection. Be careful; don't shake the glass with solution until the process is finished.

Sometimes, you may notice that still no sign of growing crystal, even a week after, but actually, our crystal is growing. Suddenly, a crystal will emerge.

When you are making magic before your eyes, it stimulates your imagination and gives you new opportunities to experiment with the world around you. Using this technique, you can create different crystal figures to make your dreams a reality.

You have to prepare a framework of wire thread wrapped, dip it into solution, take out quickly, and leave it to dry at room temperature. The salt solution will be absorbed by the thread, and when it's drying, you will notice the smallest crystalline formations on its surface.
