Picture of How to grow great crystals
After a little research on Instructables.com, I didn't find an instructable which show you how to grow big and beautiful crystals. So I think that this instructable is a good idea.
Growing crystals is more than only a instructable, it is for me a passion, so a little piece of my soul was caught in them (in crystals).
For me, the word "crystal" means something like a DNA, because natural crystals have been created long time ago, and they have a piece of time history in them.
In this instructable you'll find how to grow several crystals and tips and tricks for growing them.
To grow a big wonderful crystal or a beautiful one, you may read all this instructable.

Step 1: A little introduction in the world of crystals

What is a crystal ?
A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an ordered pattern extending in all three spatial dimensions. In addition to their microscopic structure, large crystals are usually identifiable by their macroscopic geometrical shape, consisting of flat faces with specific, characteristic orientations.(Wikipedia)

In this big world, are a lot of crystals and these crystals also have a lot of applications.
For example, your computer's processor is almost made from silicon, which is a crystal.
Or your keys, that are almost made from iron, which is a crystal too.
Or your wedding ring (if you're married), which I think it's made from gold, another crystal.

But crystals aren't all the same, they have a different structure and different properties.

Enough with talking. Let's start the work!!

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 & color to them?
andreyeurope (author)  Advar11 months ago
You can color the Alum crystal with food coloring. I have tried it with blue coloring and it works great.
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.

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.

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.
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.

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?
andreyeurope (author)  alkwan1 year ago
Crystal powder is a powder made by crushing crystals.
You can get it from Amazon or Ebay.
Just write the substance you want (for example: Alum) and buy it.

Wow. But no offence, another is one word.
andreyeurope (author)  Sassah1221 year ago
What do you mean ?
You typed it as an other. It is actually "another".
andreyeurope (author)  Sassah1221 year ago
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 "don't taste it" 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.

Please see the wiki page for more information about toxicity. http://en.wikipedia.org/wiki/Potassium_dichromate
I love that you included the "DON'T TASTE IT" notations :)
I've always had trouble making my own rock candy with sugar, especially big crystals, any suggestions?
andreyeurope (author)  Pat_Maroney1 year ago
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: "In the past, maybe now too, it was used to stop the bleeding."
Yes! Barbers (at least in Italy!) still use it in case of small cuts on customers face!
andreyeurope (author)  Ti41 year ago
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?
andreyeurope (author)  Mojo_JoJo1 year ago
I think I'll add other crystals recipes later because now I'm "engaged" with electrochemistry.

Very interesting!
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 "gold from the trash" instructable!
