It pretty much forms from no crystallization. ;)
These two terms are used to classify igneous rock. Intrusive igneous rock has solidified from magma, below the surface of the Earth. Extrusive igneous rock has solidified from lava, at or near the surface of the Earth. Intrusive rock displays a coarse-grained rock texture, a result of the slow cooling of magma. Extrusive igneous rock will display either a fine or a glassy texture, depending on the speed of solidification of the lava.
An igneous rock can change into a metamorphic rock through the process of metamorphism, which involves heat and pressure altering the mineral composition and texture of the rock. This can occur deep within the Earth's crust where high temperatures and pressures are present, causing the minerals in the igneous rock to recrystallize and form a new metamorphic rock.
Igneous is from the Latin for 'from fire'. The same root as for ignite.Igneous rocks are classed in two types, volcanic which erupt on the surface and then crystallize, and plutonic, such as granite, which crystallize under the surface.For each volcanic rock there is a corresponding plutonic, as judged by their chemistry.
A glassy countenance refers to a facial expression that is characterized by a lack of emotion or expression, often appearing cold and detached. It can indicate someone being in a state of shock, disbelief, or being disoriented.
"Born from fire" Igneous rock tends to made in volcanoes.

Glassy typically refers to something that is transparent, smooth, reflective, and shiny, resembling glass in appearance or texture. It can also describe a person's expression or demeanor as lacking emotion or expressionless.
but not
I think you mean form, so, they are cooled magma and are classified 3 ways: mineral composition (aka color) texture, or if they are made internally or externally
blurring means becoming glassy or to lose clear vision.

What does texture mean in art
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
The size of the crystals in an igneous rock tells us how fast the magma cooled.
