What is the difference between an igneous rock with a glassy texture and one with a fine texture?

The main difference is that the glassy textured igneous rock cooled from lava with extreme quickness, while the one with a fine texture cooled less quickly. Obsidian is a natural glass, created by rapidly cooling lava, where mineral crystals do not have enough time to form before the lava solidifies.

How do Igneous rock with glassy textures?
An igneous rock with a glassy texture cooled from its' liquid state very quickly, an example of this would be obsidian, a volcanic glass.

glassy texture, hope this helps :)
Igneous rocks are classified based upon their mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
