To make crystals using salt and vinegar, first dissolve salt in vinegar to create a saturated solution. Then, allow the solution to evaporate slowly in a container. As the liquid evaporates, salt crystals will form. You can also try adding food coloring to create colored crystals.
If you talk about single crystal high purity growth methods, then following are the methods:Bridgeman MethodCzochralski MethodFloating zone Method
they are the cristals which form when vinegar is left for a long time.
No, sugar crystals cannot grow in vinegar because vinegar typically contains acetic acid, which would prevent sugar crystals from forming. Sugar crystals are more likely to grow in a saturated solution of sugar and water.

Salt crystals generally grow faster than alum crystals because salt is more soluble in water and forms crystals more quickly. Alum crystals tend to grow slower due to their lower solubility in water.
To grow salt crystals on a string, you can create a saturated salt solution by dissolving salt in water. Then, suspend a string in the solution and allow it to sit undisturbed. As the water evaporates, salt crystals will form on the string.

leave it to the pros
Salt is a more cubic element than sugar
In presence of salt the crystals grow faster because the solubility of salt decreases the solubility of any other compound in water.
