[Rockhounds] Fun with Sodium Carbonate...

[Tim Jokela Jr.]

Basic crystal growing:

Make a small amount of concentrated solution and let it evaporate, forming 
seed crystals. Select the largest seed crystal, and suspend it in a jar of 
supersaturated solution, via thin monofilament fishing line and a popsicle 
stick or similar. Cover jar with cloth and a rubber band. Keep in an area of 
constant temperature and humidity if possible, and watch your crystal grow.

This works great for the easy-to-grow things like alum, dunno if it will 
work for your chemical.

Mandatory safety message: protect your eyes, lungs, and skin when messing 
about with chemicals.

"Crystals and crystal growing" by Holden & Morrison is probably the best 
book on the subject. Also a lot of info online.
