Step 2: How to make the solution (slow evaporation method)

Needed materials:
- 100 g or more crystal powder (If you want to grow a big crystals, you should have more than 100 g)
- 100 ml distilled water (or boiled water)
- patience
- filter paper
- 2 clean jars

1. Mix the crystal powder and the water.
2. Stir until the powder stops dissolving.
3. Filter the obtained solution. Don't worry if the powder wasn't all dissolved. You should keep the powder remained on filter paper.
4. Let the solution for a while. A big crystal isn't growing a sudden.
5. Next time you'll take a look at your crystals, you'll see that there have grown many crystals there. Choose one that you like (a seed) and then put the remained crystals where you put the remained powder.
6. Filter again the solution and then put your little crystal in solution. (You may do that every time you'll see little crystals.)
7. When you see that in the jar isn't enough solution to cover the whole crystal, make some new solution as you have made the first one (I mean make the solution in a clean jar, filter it and then fill the jar that have you're crystal).
8. Growing crystals takes a lot of time, so be patient.

Tips(applied for all crystals):
  • You should cover your jar with something, maybe a filterpaper, because the solution can get some impurities from the air and then will grow many "parasitic" crystals
  •  If you want to quickly grow many little crystals, you can heat the water, but if you want to grow big nice crystals, you shouldn't do that.
  • Don't put your jar on a heat source.
  • Be careful not to break the crystal. (If you break it, you'll be really dissapointed, trust me.)
  • Don't taste the crystals.
  • If you have some small crystals sticked of your crystal, put your crystal in water and let it there until you don't see the small crystals.
  • If you want to quickly grow a little crystal, you can put a little "crumb" from powder as seed.
<p>Nice info, its great feeling to grow crystals and examine them. awsome chemistry</p>
Thanks. I know it's a great feeling, but you also need a lot of patience. Every nature made thing it's awesome, because even if you can't grow nature made crystals, it's nice that you can make simpler versions of them.
Thanks for the instructable. Can you grow crystals onto fabric?
<p>Thanks for the instructable, I plan to make a variety of crystals for a school project.</p>
<p>Would it be possible to grow amethyst crystals?</p>
Unfortunately no, because they are natural crystals. They are not water soluble. So it's almost impossible to grow one home.
<p>Yes i checked that Amethyst is a type of quartz with certain ''extra'' compunds that give it's natural color. I also found that it's base formula is SiO2, and that it requiers hi preasure to make a synthetic quartz. However I have another question. I noticed that formula for turquoise is ''Cu(Al,Fe3+)6(PO4)4(OH)8*4H2O'' Meaning that it is a crystal hydrate, and it's hardness is 5-6. That said would it be possible to create turquoise crystal at home from a powder using the method described in this instructable? </p><p>Same question about tourmaline, thou it's chemical formula is a bit different.</p><p>http://www.minerals.net/tourmaline_chemical_formula.aspx</p>
<p>I'm not sure if you can grow turquoise home because it's also a natural crystal, so almost all nature-made are impossible for us to be grown home.</p><p>Even if somebody succeed in creating a synthetic crystal, it won't be as beautiful as the original one.</p>
<p>First of all I love the instructable I am a huge fan of crystals so I was wondering if I could do something for Halloween which would be that if I could grow crystals on my arm I will use some sort of transparent latex cover for it but I was wondering do you have any suggestions on which crystals I should use? I would like to have the color be either a amethyst color or a calcite sort of color and when it comes to the shape I would like for it to be a Quartz sort of shape. The image below is how I want for it to turn out in the end sort of but only for the arm. Also I want for it to be safe so that people can thouch it but not taste it.</p>
What other things can I use to make crystals, like household things besides salt...
<p>You can use Borax</p><p>https://www.youtube.com/watch?v=BHRFBKjqEvg</p>
I think you should have the tutorial of growing great salt crystal!
<p>any suggestions for crystal material?</p>
What do you mean by crystal material?
<p>Is this the same alum that I buy in the grocery store and use when I can some types of pickles?</p>
<p>If on it's label is written KAl(SO4)2. then it's good.</p>
awesome... I hope I can collect the things to do this
Nice 'ible. If making non-toxic crystals (clear) could a drop of food coloring or pen ink be used to add tint &amp; color to them?
You can color the Alum crystal with food coloring. I have tried it with blue coloring and it works great.<br>The Alum isn't toxic so you can taste it.
Thinking of handling and spillage, but good to know. Thanks. :)
As a Molecular Biomedicine student at the University of Copenhagen a work with a wide range of chemicals daily and I do not recommend people, who don't have proper labs or lab experience to work with chemicals such as Potassium Dichromate, potassium Nitrate or Iodine compounds. Improper handling can cause serious injury or worse. Potassium Nitrate (from the Gold Rain crystals) is a strong oxidizer which means that it can make even harmless, household chemicals into harmful compounds. Iodine compounds, Nitates and Potassium Dichromate can if not treated right produce some noxious gases. <br> <br>Further more I would seriously warn people against making jewelery of toxic chemicals. One thing is to wear toxic jewelery another thing is the dire consequences of children snatching them from the jewelery box. <br> <br>Some of the mentioned chemical only require as little as 2.6 grams to potentially kill a child with a weight of 10 kilos. Twice that amount to twice the weight. If not fatal, some of the chemicals are carcinogenic or mutagenic (Potassium Dichromate is both) so long term effects can be serious. <br>Moreover some of these crystals will over time decompose, some into hazardous gasses, storing them in closed boxes will accumulate these gasses and therefore concentrated if the box is opened. <br> <br>I for one would not make these crystalt for garnish unless they would be proper sealed.
Thank you for this comment. I will modify this Instructable.
Whats crystal powder? Where do I get it?
Crystal powder is a powder made by crushing crystals. <br>You can get it from Amazon or Ebay. <br>Just write the substance you want (for example: Alum) and buy it.
Wow. But no offence, another is one word.
What do you mean ?
You typed it as an other. It is actually &quot;another&quot;.
Can you tell me where?
Also in the 4th step, last image.
The 9th row bellow the picture for step 1 (Ctrl-F anyone?)
I really like your Instructable and the &quot;don't taste it&quot; warning is sufficient for most of the crystals. While i do not think that anyone who is not working in a lab can even get the Potassium Dichromate, it should still be mentioned that it its really really really toxic and should not be handled without gloves (non of these crystals should actually be touched without gloves, except if you're making sodium chloride crystals.). The solid dichromate should not be handled outside of a fume hood. It is really carcinogen, mutagen and highly toxic. Waste waters should in no case be disposed into your sink. <br> <br>Please see the wiki page for more information about toxicity. http://en.wikipedia.org/wiki/Potassium_dichromate
I love that you included the &quot;DON'T TASTE IT&quot; notations :) <br>I've always had trouble making my own rock candy with sugar, especially big crystals, any suggestions?
I'll try to do every crystals you want, but not now. I'm still student. I'll try to make it as fast as I can. Thanks for comment.
This is the best tutorial I've read this month, bravo. Can't wait to try it
Thank you.
About Alum: &quot;In the past, maybe now too, it was used to stop the bleeding.&quot; <br>Yes! Barbers (at least in Italy!) still use it in case of small cuts on customers face!
I know. My grandfather was using it.
With a sensitive enough opamp you could use the piezo crystals as a homemade pressure sensor or drum pads for a homemade drum machine. You don't need any information from the strike, other than the fact that it was struck, but if the voltage increases with force even better - you can respond to different levels of pressure.
I know. You can use them too to make a microphone.
very interesting, a long time ago (in 5th grade) I accidentally grew salt (NaCl) crystal that grew into a beautiful snowflake type pattern, unfortunately I haven't been able to repeat the result. How can other common (safe?) household chemicals be used such as salt, sugar, boric powder or even just grow a snowflake in the deep freezer?
I think I'll add other crystals recipes later because now I'm &quot;engaged&quot; with electrochemistry.
Very interesting! <br>
cool! voted!
do anyone know why isn't this instructable featured ?
Wow, so many pretty gems... Definitly worth looking into , thanks for sharing!
Hmm, very interesting! I'm enjoying looking at the chemical equations, as that is was I'm studying in my physics at the moments.
Splendid project! I look forward for a &quot;gold from the trash&quot; instructable!
