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.
  • WARNING: DO NOT TOUCH OR TASTE THE CRYSTALS OR THE SUBSTANCES USE FOR MAKING THEM!! SOME OF THEM ARE HIGHLY TOXIC (POTASSIUM DICHROMATE, POTASSIUM NITRATE or IODINE COMPOUNDS)!!! IF YOU WANT TO TOUCH OR TASTE THEM ASK A SPECIALIST!!
Do you have any experience with growing durable clear crystals? It looks like Alum crystals are simple to grow, but aren't very strong and break easily? I'm doing an art project but need strong, durable clear crystals. Any help would be greatly greatly appreciated. Thanks!
Hi there. Yeah, I have some experience with growing crystals, but growing a durable one means a lot of time. There a currently multiple way you can use in order to grow a nice big crystal, but don't expect hand-size crystals. Also, growing a clear crystal means maintaining its structure while keeping it away from any other crystal. It is like growing flowers. In a garden, weeds appear too. So you will have to remove the weeds (other crystal seeds that might attach to your big crystal).<br>For some crystals, which have growing time big when compared to others, it is quite easy to maintain this structure, but other crystals, like copper sulfate are hard to maintain, as they grow pretty fast.<br>You can apply a varnish layer in order to maintain crystal look, but durability is not a feature of the growable crystals.<br>Only nature (and devices) can provide durability using specific conditions like high atmospheric pressure or high temperatures.
How long does this take?
<p>If you are referring to growing a crystal, then it takes how big you want your crystal to grow. A big nice crystal can take months to grow.</p>
<p>Very neat instructable, I wonder if I can grow crystals that will give me +2 Strength, +3 Dexterity, +2 Intelligence +3 Mana :)<br><br>Anyways, when I was a kid I have found a stone in nearby mountains, inside it is a colorless crystal, like the whole stone, I wonder what it is. I'll try to find one and post it here.<br><br>Also, my friend found an obsidian crystal, I wonder how it is worth.<br></p>
<p>Obsidian is a natural glass produced through volcanic activity. It is not a crystal. While it is used to make jewelry, obsidian is not particularly valuable, though it does look pretty cool. </p>
<p>Yeah they do look cool (especial) when they're shinny you may want to consider a shiner to make it look better (depending on how it looks) </p><p>P.S I think lacquer may work but i'm not sure</p>
So, are all these crystals water soluble?
Yes, but if you apply polish on them, they can last and have a protection layer against water.
<p>I very new to growing crystals...grew my first Borax crystals last night. From what im reading...If I crush my amethist crystals...and add the result to say hot water and let stand...I should get new crystals? Forgive my ignorance.</p>
Unfortunately no, they are not going to grow again. They are nature-made crystals. You need some special conditions in order to grow them.
<p>Nice, good job mate!</p>
<p>I did copper sulphate in chemistry. My teacher gave me all that was made so that I could make a big crystal, but I screwed it up. I was wondering if a clear coating could be applied to protect the crystal from water and probably any people that would want to touch it.</p>
I think that applying an acrylic coating may save your crystal from water and people.
<p>Nice job, thanks for sharing!</p>
<p>Fascinating! But... what is crystal powder and how to obtain? Info has ghly appreciated.</p>
<p>Crystal powder is like ground meat. I mean you can obtain crystal powder by smashing or crushing a big crystal. The crystals are crushed because the crystal powder is more soluble than a big crystal.</p>
Thanks, but I am fond of my crystals. Cannot get myself to destroy one to make another. I'd rather use something else if that's possible.
<p>Yeah, but if you don't like how your crystal looks, you can make it reborn. :D</p>
<p>thanks again, another question: which instrument do you use to smash a big crystal to turn it into powder?</p>
<p>You can wrap the crystal with a kitchen rag or an old T-shirt you don't mind to ruin. You can smash it with a hammer.</p>
So your saying that iron is made of iron crystals or iron ore and if o smash an iron pipe i can use the powder, in that aspect your stating that i can grow gold!! Sign me up skippy. All joking aside i found your instructable extreemly informative and entertaining. I find that instructables such as yours are the reason I keep coming backso keep up the good work and thank you very much for your efforts and your time .
<p>Good joke, but unfortunately iron crystals don't really exist in nature. But you can find it in composite substances like iron pyrite. That's a beautiful nature-made crystal. It looks like gold. Also, in order to create a crystal, you need a good amount of powder. So even it was possible to grow gold, you would need a lot of gold. :))</p><p>I'm glad that many people appreciate my work and I hope new Instructables will appear with more crystals than mine.</p>
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.
<p>Wear gloves so the dye won't stain your hands.</p>
Thinking of handling and spillage, but good to know. Thanks. :)
<p>Is this the same alum that I buy in the grocery store and use when I can some types of pickles?</p>
<p>Go to Amazon. I bought a pound of Alum for about 7.50 dollars.</p>
<p>If on it's label is written KAl(SO4)2. then it's good.</p>
<p>Copper Acetate crystals are fairly easy to grow and are, to my eye, lovely.</p>
<p>Fascinating! But... what is crystal powder and how to obtain? Info has ghly appreciated.</p>
<p>What an awesome instructable! Thank you so much for all the work you put into this. Your passion for the subject makes it extra interesting. Can't wait to set aside some time to give this a try. </p>
I'm glad you like it. I like crystals, not for their value, but for their age. They are like Earth memories encapsulated in one small and beautiful piece of art.
<p>if you can't touch em or eat them, what's the point of making them other then bragging rights? Is there a use for the ones that can't be eaten or touched? </p>
What other things can I use to make crystals, like household things besides salt...
<p>you can use borax.</p>
<p>You can use Borax</p><p>https://www.youtube.com/watch?v=BHRFBKjqEvg</p>
<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>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>
<p>any suggestions for crystal material?</p>
What do you mean by crystal material?
awesome... I hope I can collect the things to do this
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.
