How much Borax do I need to make Borax crystals?
When you are making borax crystals you want 1/8 a cup of borax for every cup of water.
How Long does it take for Borax crystals to start growing?
Crystals will form in as little as two hours. For best results, avoid disturbing them for 24 hours.

How to Dry Borax Crystals
After you make the borax crystals in the jar solution you will need to let them dry out before handling them. All you have to do is lay them out on paper towels and allow them to dry out completely.
How to Remove Stuck Borax Crystals
Sometimes when making borax crystals, you may end up with crystals stuck to the side of the container you grew them in. It is easy to remove any crystals that are stuck and have grown on the side of the jar. All you have to do to remove the stuck crystals is simply fill the jar with hot water and let the Borax dissolve.

Borax Crystal Shamrocks Supplies
- 2 cups water
- ¼ cup Borax detergent booster
- 2 Green pipe cleaners, 1 for each crystal
- Scissors
- 2 Glass Jars
- Thread or thin string
- 2 Popsicle sticks
How to Make Borax Crystal Shamrocks
Twist 2 green pipe cleaners into a shamrock shape, giving you 2 shamrock shaped pipe cleaners.


Attach a string to the pipe cleaner by tying it. Attach the pipe cleaner to the popsicle stick.

Pour 1/2 the borax powder in to each glass jar.
Next warm up the water up in the microwave so it is hot. You don’t need it to be boiling, but hotter than average warm tap water. The hotter the water the better they will grow, but you do not want it boiling.

Slowly pour 1 cup of water into each jar. Pour slowly to allow the jar temperature to adjust so it does not crack. Stir the mixture until all of the borax powder is dissolved.

Carefully drop one pipe cleaner into each jar with borax solution so it hangs in the middle of the jar without touching the edges or bottom.

Use the popsicle stick to adjust the length of the string by wrapping the string around it if needed. Lay the popsicle stick flat across the top of the jar so it holds the pipe cleaner in place in the jar.
Place jar in an area where it will not be disturbed and wait for the crystals to grow.
Once they have formed, remove them while attached to the sticks from the borax solution.
Allow them to dry out a bit. While you can look and touch them just about as soon as you remove them from the solution, they will be even more gorgeous if you allow them to dry.
