Massive Single Crystal!!!

I never thought that something like this was possible!!....

This is a synthetic seed crystal. It is placed in a six-foot-high tank filled with nearly a metric ton of supersaturated potassium dihydrogen phosphate (KH2PO4), or KDP. As it rotates on a turntable in the tank, the crystal begins to grow. In just two months, the crystal grows to be as large as 800 pounds; with conventional methods of growing crystals, this process would take nearly two years. When complete, the crystal is carefully cleaned. It's removed from the tank. Then it's measured; and finally, it's cut into 40-by-40-centimeter plates to be used in the National Ignition Facility to focus, transmit and direct laser beams on their way to the target chamber.

Amazing Crystal Cave

The BIGGEST CRYSTALS in the world!! Some of them are more than 10 meters long!! They are made of selenite which is a form of gypsum (Spanish: yeso). Its formula is CaSO4.2 H2O.

Cave of the Crystals (from wikipedia)or Giant Crystal Cave (Spanish: Cueva de los Cristales) is a cave in Mexico. The main chamber contains giant selenite crystals, some of the largest natural crystals ever found. The cave's largest crystal found to date is 11 m (36 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight. The cave is extremely hot with air temperatures reaching up to 58 °C (136 °F). The cave is relatively unexplored due to the extreme temperatures and high humidity. Without proper protection people can only endure approximately ten minutes of exposure at a time.

Exothermic Reaction Molten Magic

Supersaturated solution of NaAcO strikes back again!!

Golden Rain (precipitation of lead (II) iodide)

"Gold" like PbI2 crystals precipitate from a saturated solution in water. The solution is obtained dissolving PbI2 in hot water which will become saturated as the temperature goes down....
