What makes glass clear?

It is a solid so what makes it so special that light can pass through it?What makes glass clear?
Sorry but It is an Urban legend that glass is a liquid :(








For those that are asserting that glass is a liquid then I refer them to the following link. http://www.weburbia.demon.co.uk/physics/鈥?/a> if you only read one part then read the conclusion!





and to Florin Neuman's paper http://dwb.unl.edu/Teacher/NSF/C01/C01Li鈥?/a>





Though it does have some liquid like properties (disordered structure) it also has solid properties (elasticity). Glass's behaviour is not that of a highly viscous liquid. Glass doesn't flow!





As to why you can see through glass http://science.howstuffworks.com/questio鈥?/a>What makes glass clear?
That's a really good riddle
Glass isn't a solid, it's actually a liquid... strange but true!





You can see through it for the same reasons that you can see through water.





Conventional liquids, when cooled, have a freezing point at which they suddenly become solid. Liquid glass, by contrast, simply gets gradually stiffer as it cools. At room temperature its rate of flow is so slow that it would take billions of years to ooze out of shape, and for most practical purposes it may be treated as a solid.





Its internal structure, though, is not the regular crystalline latticework of your standard solid, but rather is essentially random, like the typical liquid. As with many liquids, the rather loosely spaced molecules in glass are simply not big enough to obstruct the passage of light particles.
Actually, glass is a liquid which just flow very very very slow (high viscosity). Crystal glass is a solid. It's not because something is solid that it shouldn't be clear, a liquid on the other hand is often not clear either. You can look through water, glass, and many other things because the visual light is not completely scattered by the molecules and the structure that make up the material.
The fact that you can see through it?
