On cooling saturated solutions, the excess solute precipitates as a solid. This can take the form of a powder or a crystal structure.

When a solution is saturated that indicates that solution is at a maximum concentration. The solvent is unable to dissolve more of the solute. If more of the solute it placed in the solution, it will not dissolve, yet rather sit at the bottom as a crystallised form. The temperature can also affect the capacity of the solvent's abilities to dissolve the solute eg. it is easier to dissolve sugar into a drink if it is hot than when it is cold. Sometimes if the drink cools down, the crystals settle at the bottom. -- Neenish Tart
A saturated Soda (Sodium Carbonate) solution can be used to grow crystals but it is not a good choice because the resultant crystals will dry out in air and effloresce ("flower out") to form a white powder.
On heating a saturated solution it becomes unsaturated because heating causes kinetic energy to increase the distance between the molecules of liquid. Thus the solute takes free space present in the solvent. That is why saturates solution becomes unsaturated upon heating.
Sugar crystals form from over saturated sugar in the mixture.
Yes it will produce condensation
Crystals in general are formed when solutions try to maintain concentrations at or below saturation. For example, a saturated sugar solution forms crystals when water from the solution evaporates and leaves excess sugar behind. Since supersaturation is a highly unstable and thus undesirable state of being for a solution, the dissolved sugar left behind will clump together at sites of nucleation to let the remaining solution remain below supersaturation. Crystals will continue to grow as long as the concentration of solutes in the solution can increase above saturation. To grow large blue vitriol crystals, one can simply prepare a saturated solution in a large container and let it sit undisturbed for as long as possible while evaporating steadily, removing the crystals when they are a satisfactory size or before the solution dries up entirely.

A solute dissolves in a solvent to form a solution; all the time that more of the solute can be dissolved it is unsaturated, but once the solution can hold no more of the solute it has become saturated.

We often find that there is a limit to the quantity of solute which will dissolve in a given quantity of solvent. This is especially true when solids dissolve in liquids. For example, if 36 g KCl crystals is shaken with 100 g H2O at 25°C only 35.5 g of the solid dissolves. If we raise the temperature somewhat, all the KCl will dissolve, but on cooling to 25°C again, the extra 0.5 g KC1 will precipitate, leaving exactly 35.5 g of the salt dissolved. We describe this phenomenon by saying that at 25°C the solubility of KCl in H2O is 35.5 g KC1 per 100 g H2O. A solution of this composition is also described as a saturated solution since it can accommodate no more KCl. Under some circumstances it is possible to prepare a solution which behaves anomalously and contains more solute than a saturated solution. Such a solution is said to be supersaturated. A good example of supersaturation is provided by Na2S2O3, sodium thiosulfate, whose solubility at 25°C is 50 g Na2S2O3 per 100 g H2O. If 70 g Na2S2O3 crystals is dissolved in 100 g hot H2O and the solution cooled to room temperature, the extra 20 g Na2S2O3 usually does not precipitate. The resulting solution is supersaturated; consequently it is also unstable. It can be "seeded" by adding a crystal of Na2S2O3, whereupon the excess salt suddenly crystallizes and heat is given off. After the crystals have settled and the temperature has returned to 25°C, the solution above the crystals is a saturated solution-it contains 50 g Na2S2O3. Another example of crystallizing salt out of a supersaturated solution can be seen in the following video. In this case, a supersaturated solution of sodium acetate is poured over a crystals of sodium acetate. These crystals provide the lattice structure "seed" which causes the sodium acetate ions in solution to crystallize out. The video begins with a few crystals of sodium acetate placed on the lab bench. A supersaturated solution of sodium acetate is poured over the crystals providing a seed or crystallization. The salt begins to crystallize, forming a large sodium acetate structure from the precipitation of the ions out of solution. When the sodium acetate crystallizes, the oppositely charged ions are brought closer together by the crystal structure. Since formation of a crystal lattice lowers potential energy by placing like charges close together, the system releases the excess energy in the crystallization process. Thus, the structure ends up being warm to the touch from this excess energy.

Sugar crystals form from over saturated sugar in the mixture.
When some of the material being dissolved remains it's called a saturated solution
Any kind of salt solution can be left in an evapouration dish to form crystals, and a common salt used for crystal growing is copper sulfate, which grows nice blue crystals. A lot more things can form crystals, for example isolated hormones create beautiful crystals and steric acid, one of the main ingredients of candle wax grows crystals when cooled to a solid state ( its just that they are extremely small, but the slower they cool down, the bigger the crystals will be).
