Yes. Natural forms of glass can be produced by both lightening and meteors. When lighting strikes soil with lots of sand in it (sand being a natural form of silica, the same stuff glass is made of), it can melt the sand into glass, creating formations known as “Fulgurites”. The world record fulgerites was composed of two thin tubes of natural glass, one 16 feet long and the other 17 feet long.
Indeed it does! Obsidian is a natural black glass that is made due to volcanic activity. When lava comes in conact with water, obsidian is the black, shiny result.
