Suspend a string into a glass of salt solution and allow the water to evaporate, the salt will collect on the string in crystals. Making rock candy can be done the same way if you use sugar instead.
There are two ways, the quick way, and the slow way.
Way One:
1) Find a glass, and fill it with hot water.
2) Add in regular table salt (just table salt because it's chemical composition is sodium chloride - Na + Cl)
3) Keep mixing in the table salt until the water can't absorb anymore salt.
4) Set the glass in the microwave and boil off all the water, or if you're one of the cautious ones, just set it out in the sun to evaporate.
Way Two:
1) Do same things as steps 1-3 in Way One, but after that take a pencil and tie a string to it. At the end of the string, tie a heavy object, but make sure it isn't metal because if it is, it will rust and give the water a horrid look and smell.
2) Drop your string into the center of the glass.
3) Set the glass in a sunny window, or a place where it won't be disturbed for at least a few weeks.
4) Extract your crystals.
The table salt by the way are already iodized salt crystals, but just crushed up into small pieces.
Evaporating slowly water from a sodium chloride solution we can obtain crystals.
iodine crystals are black, table salt crystals are white.however I doubt that was your question. I think you are referring to iodized table salt. there are no iodine crystals in iodized salt, instead they add sodium iodide to the table salt. sodium iodide crystals are indistinguishable visually from the sodium chloride crystals of table salt.the only practical way to separate sodium iodide from sodium chloride is the very tedious repetitive process of dissolving the mixed salts and performing fractional crystallization of the solution.
After the recommendation of WHO table salt must be iodized in all countries.
Alternative Methods of Producing Iodized Salt
It is only a legend; you can use iodized salt.
Iodized salt has a little bit of iodine added to it. This is to prevent iodine-deficiency diseases like goiters
Iodized salt, due to its relatively smaller crystal size. The smaller the salt crystals, the faster they will dissolve.
iodized wors better ---------------------- Any difference exist.
At equivalent temperature and size of the crystals any difference exist.
well you dont there made by god.

Sodium chloride (iodized table salt has small amounts of potassium iodide added) is not as soluble as magnesium sulfate (epsom salts). As two solutions with the same concentration cool down the sodium chloride will reach saturation first and produce crystals.
A salt with fine granulation is dissolved faster; also the solubility increase with the temperature. Stirring improve the speed of dissolution. Any difference between iodized or not iodized salt.
Iodized salt is the best to use !
Iodized salt is not organic. It's inorganic.

why is iodized salt important to the midwest
Iodized salt comes from Iodine, a necessary micronutrient!
