When do glassy rock form?
Glassy rocks form near or in volcanoes, or just under high pressure and heat. For volcanoes, lava will harden on the surface for active volcanoes, and will harden inside the volcano if it's inactive. Under normal circumstances, such as with sedimentary rocks, rocks deep within the earth will become pressurized and flatten, then heat up, creating a glassy rock.
