When magma coos slowly, it allows large crystals to form. The process of evaporation helps to form crystals.
Large, well formed crystals form in solutions that cool rapidly. When solutions cool slowly, crystals are more likely to nucleate in higher numbers at the same time, leading to many very small and irregular shaped crystals.
Large crystals form when a rock cools from magma slowly whereas smaller crystale form when there is a slow rate of cooling

No. Small crystals form.
The crystals may display a "Crescumulate texture".
If the magma cools down fastly the crystal size is small because the crystals do not have much time to form. If They magma slows down slowly the crystal size is big because it gives the crystals time to form! :D

Intrusive rocks are igneous rocks that form when magma solidifies below the Earth's surface. They usually form by rather slow cooling, which allows time for large crystals to grow, and these large crystals tend to give them a coarse grain. Extrusive rocks are igneous rocks that form when magma solidifies above the Earth's surface. They usually form by comparatively rapid cooling, which does not allow time for large crystals to form, so they are often fine-grained or amorphous.

Salt crystals are face-centered cubic.Sodium chloride form large crystalline lattices.

Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.
A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.
