Crystal growth “On the rocks” web.ist.utl.pt/clementina/cristais Make a saturated solution in a beaker at about 60-80 ºC (water-soluble compounds). Put the rock fragment or shell carefully inside the beaker, immersing it completely. Cover the beaker with plastic foil to reduce evaporation. Let it cool undisturbed as slowly as possible (inside a warm water bath). After 1-2 days, make some holes in the foil to allow evaporation of the solvent. Wait for a few days. The temperature should go down to ~5ºC (use a refrigerator). Remove the rock with the crystals (any rock or shell for copper sulfate, GRANITE!). Recover the solution, by filtration, for other preparations. Wash the crystals gently in very cold water, afterwards in ethanol, if necessary. Dry the crystals in cold air and protect them with a layer of nail polish. Keep them inside a transparent plastic or glass box sealed with silicone wax. Protect from light, dust, heat and humidity.
