The process of growing crystals can take several weeks, depending on the saturation of the solution that is used in the initial phases of the process. To follow these methods, you need water, a solute like salt or sugar, rocks, a coffee filter and a stove.Know More
Select a solute that can be used to create a saturated solution. Common choices for a solute for a crystal-growing project include salt or sugar, because they are safe and easy to obtain. A more saturated solution results in better chances of crystal growth. Add your solute to your water after boiling the water on the stove, and mix the solution thoroughly.
Dump the contents of your saturated solution out over the rocks that you have prepared. This results in a clumping of different crystals, known as a crystal garden. Cover the rocks and the solution with a coffee filter.
Wait for the solution you have poured out to dry. The crystals form on their own. This process can take several days or even weeks. The crystals form more quickly if the solution that was created in Step 1 was more heavily saturated with the solute.
Depending on the method used to grow salt crystals, formation of crystals occurs within several hours or a couple of days. Both methods require boiling hot water to melt the salt.Full Answer >
Crystals form by a process called nucleation, which takes place in solutions containing a high concentration of the solute. Once a nucleus is formed, the solute particles bind to it, thereby causing the growth of a crystal.Full Answer >
Crystals grow in different shapes because of the internal symmetry of the crystal and the growth rate along the direction of the crystal. The arrangement of the atoms in a crystal is called a lattice. In a perfect environment, the crystal faces that form reflect the internal atomic lattice.Full Answer >
Crystals break down into four primary types: ionic, molecular, metallic and covalent. These categories divide crystals into groups with other crystals bearing similar physical and chemical properties. Factors determining the specific variety of crystals include the size and shape of surrounding lattice, particles on certain points in the lattice and attractions or bonds existing between crystal particles.Full Answer >
