30 IV Crystals in Classroom and Home even a piece of paper would do. Do not screw a lid onto the jar that would trap the heated vapor in the jar. If you did this it might explode. Rest the bottom of the jar on a lighted light bulb in a lamp. Very soon (with a 100-watt bulb) you will see little crystals start to form on the upper part of the jar, where the warm, invisible, naphthalene vapor is cooled and the attraction of the invisible particles of naphthalene for each other brings them together in the orderly arrangement of the naphthalene crystal.
All that part that reflects light at the same angle (that looks bright when you stand in one place) belongs to a single crystal. 2 Jewelry stores Nearly all gem stones are single crystals. Exceptions are jade and cat’s-eye, which are polycrystalline, and opal, which is not crystalline at all. Most gems are cut with many-sided surfaces, both on the top surface and on the bottom. Light reflects from the top facets, but also enters the gem and reflects back out again from the bottom surfaces. This gives the gem its brilliance, and great care is taken to cut the small surfaces at the most favorable angles to achieve this.
