Yes. Salts can form crystals (salt crystals).
Most are because they take millons of years to form
It can take a couple of days.
it could take days to weeks
how long they stayed in the volcano; how much time the crystals had to form
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
