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!!
