Recipes for Crystal Growing Solutions

Recipes for Crystal Growing Solutions Find a crystal growing recipe. This table includes recipes for preparing solutions of common crystal grown in aqueous or water solutions. 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, its 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.
