Slice an eighth inch layer of granite from a slab and throw a rock at it. You would find that it breaks much like a piece of window glass. Adversely, cast a slab of window glass four inches thick and you will find yourself with a very rugged material. Despite common myth, the molecular structure of glass is not liquid but solid. It does not droop with time, does not melt with age, or rest in an unstable state.
Granite and glass have very similar properties and rival each other as durable exterior sculptural components. Glass bowls have been discovered in the Middle East that date back over 4,000 years. French cathedrals contain stained glass that has withstood 700 years of war and weather and shows little sign of surrender. Cities throughout the world have glass tiles in their sidewalks and glass walls containing their skyscrapers. Chances are you could look around you and find dozens of examples of glass that you live with - glass that hasn’t changed form or appearance since the day it was created.
