How to make crystals at home?

Easy Crystal Growth Recipes:

Easy crystal growth recipes are listed here briefly. Crystals can be made in several ways. This is a collection of easy crystal growing recipes, with photos of what the crystals look like and tips on how to make your crystals a success.

Sugar crystals or rock candies

Easy crystal growth recipes.This blue rock candy is practically the same color as the sky.
Blue rock candy
This blue rock candy is practically the same color as the sky. Rock candy is made from sugar crystals. It is easy to color and flavor the crystals. 

Rock candy or sugar crystals are particularly good to grow because you can eat the finished crystals! The basic recipe for these crystals is:

  • 3 cups of sugar
  • 1 cup of boiling water

You can add food coloring or seasoning to the liquid if you want. It is easier to grow these crystals on a thick cord that hangs from a pencil or knife in the solution. For best results, remove any crystals that are not growing on your chain.

Easy Alum crystals growth recipes :

Easy crystal growth recipes. This is a unique alum crystal.
Unique Alum crystal
This is a unique alum crystal. The crystal form is the most common form taken by alum crystals grown under ordinary household conditions.

These crystals look like diamonds, except that they are much larger than all the diamond crystals you are likely to see! Alum is a cooking spice, so these crystals are not toxic, although they don’t taste good, so you won’t want to eat them. To make alum crystals, simply mix:

  • 2-1 / 2 tablespoons alum
  • 1/2 cup very hot tap water

The crystals should start to form in your container within a few hours. You can also grow these crystals on rocks or other surfaces for a more natural look. The individual crystals can be scraped off the container with a fingernail and left to dry on a paper towel. More ”

Easy Borax crystal growth recipes :

Borax crystals
You can grow borax crystals on a star shape to form borax crystal stars.

These naturally clear crystals are easy to grow on pipe cleaner forms. Choose a colorful pipe cleaner or add food coloring to get colored crystals. All you need to do to prepare the solution is to pour boiling water into your container and mix the borax until nothing more dissolves. An approximate recipe is:

  • 3 tablespoons borax
  • 1 cup of boiling water

These delicate crystal tips grow in a cup in your refrigerator in a matter of hours, or sometimes faster. Simply mix together:

  • 1/2 cup Epsom salt
  • 1/2 cup very hot tap water
  • food coloring (optional)

Place the cup in the refrigerator. Be careful when collecting the crystals to examine them, as they will be fragile.

Easy Copper sulphate crystal growth recipes :

Copper sulphate crystals
Copper sulphate crystal. 

Copper sulphate crystals naturally form blue diamonds. These crystals are extremely easy to grow. Just dissolve the copper sulfate in a cup of boiling water until it no longer dissolves. Let the container sit undisturbed overnight. It is best to collect the crystals using a spoon or toothpick, as touching the solution can make your skin blue and cause irritation.

Sodium chloride or table salt crystals

Easy crystal growth recipes. These are salt or sodium chloride crystals.
Table salt crystals
They are salt or sodium chloride crystals with a cubic crystal structure. Salt crystals are indicated with one euro cent for the scale. 

This project works with all types of table salt , including iodized salt, rock salt and sea salt. Just mix the salt in boiling water until it no longer dissolves. The solubility of salt is highly dependent on temperature, so hot tap water is not hot enough for this project. It is good to boil the water on the stove while stirring in the salt. Let the crystals sit quietly. Depending on the concentration of your solution, temperature and humidity, you may get crystals overnight or it may take a few days for them to form.

Chrome Alum Crystal

Easy crystal growth recipes. It is a chromium alum crystal, also known as chromium alum.
Chrome Alum crystals
It is a chromium alum crystal, also known as chromium alum. The crystal has the characteristic purple color and the octohedral shape.

The chromium alum crystals are dark purple in color. Just prepare the crystallization solution and let the crystals form.

  • 300 grams of chromium and potassium sulfate (chromium alum)
  • 500 ml of boiling water

The solution will be too dark to observe the growth of the crystals. You can check for growth by shining a flashlight in the solution or by carefully tilting the solution to the side. Do not spill! Disruption of the solution can slow your results, do not check more often than necessary.

Copper acetate monohydrate

Easy crystal growth recipes. These are copper (II) acetate crystals grown on a copper wire.
Copper acetate monohydrate crystals
These are copper (II) acetate crystals grown on a copper wire. 

Copper acetate monohydrate produces blue-green monoclinic crystals. In order to create these crystals, you will need the following:

  • 20 g copper acetate monohydrate
  • 200 ml of hot distilled water

 

Potassium dichromate crystals

The potassium dichromate crystals occur naturally in the form of rare mineral lopezite.
The potassium dichromate crystals occur naturally in the form of rare mineral lopezite. 

You can add food colors to clear the crystal solutions to make them orange, but these potassium dichromate crystals come naturally by their bright orange color. Prepare the crystallization solution by dissolving as much potassium dichromate as you can in hot water. Take care to avoid contact with the solution, as the compound contains toxic hexavalent chromium. Do not handle the crystals with your bare hands.

Monoammonium phosphate crystals

This single crystal of ammonium phosphate grew overnight.
This single crystal of ammonium phosphate grew overnight. The green tinted crystal looks like an emerald. Ammonium phosphate is the most common chemical found in crystal culture kits.

It is the chemical supplied in most crystal growing kits . It is non-toxic and produces reliable results.

  • 6 tablespoons of mono ammonium phosphate
  • 1/2 cup very hot tap water
  • food coloring (optional)

Sulfur crystals

Crystals of the non-metallic element sulfur.
Crystals of the non-metallic element sulfur.

You can order sulfur online or find the powder in stores. These crystals grow from a hot melt rather than a solution. Just melt the sulfur in a saucepan over a flame or burner. Take care that the sulfur does not ignite. Once it has melted, remove it from the heat and watch it crystallize as it cools.
