Crystal Growing Solution Tips

In most cases, prepare a crystal growing solution by dissolving a powdered or granular solid in boiling water. You want a saturated solution, so dissolve as much of your chemical, called the solute, as possible in the water, which is your solvent. Usually it's fine to add too much solute to the water, so that you get some undissolved material at the bottom of your container. Filter this liquid through filter paper, a coffee filter or a paper towel and use the filtered solution to grow your crystals.
