How to grow beautiful crystals of salt - do your chemical experiment!

for people who cant understand.... the process is basically, 

1. dissolve salt of your choice into a hot solvent until it become a saturated solution 
2. filter the solution to get rid of impurity 
3. add some salt as seed and wait for crystallization to happen. 
4. after crystallization have occur, extract the crystal and choose a suitable crystal for further crystallization. 
5. tied that crystal into a rig that allow it to be suspended into the saturated solution for further crystallization to increase its size. 
6. filter the solution daily to keep any impurity from mixing into the crystal. 
7. extract the crystal once it reach a suitable size and apply clear nail polish or any kind of vanishes for protection of the crystal.
