[QUOTE="RichHorror:730772"]Strange as it may seem, glass is a liquid. How can this be? It is surely a brittle transparent solid? But no, as surely as a dolphin is not a fish, glass is not solid but liquid. To understand this, it's important to see that liquids aren't all the same as each other. (But hang on a bit, this can't be right, can it? Note: Please read the whole page before passing comment on this!) Water, the obvious typical liquid which others are compared against, isn't the same as liquid nitrogen or liquid metal mercury. More notably in the strange business about glass, syrup and treacle are notably different to water. It's much more difficult to stir treacle. This property of being difficult to stir is known scientifically as Viscosity. Some liquids have a very high viscosity and flow so slowly that by the time a can of liquid falls over there is time to pick it up before it spills! The ultimate example of a high viscosity liquid is glass. The viscosity of glass is so high that even though it's a liquid it looks like a solid. But if you could see glass from the comfy seat of a time machine, you'd see glass flow like syrup. If this seems too strange to be true, take a look at reflections in window panes and glass on framed paintings that are very old. Glass that's a hundred years old is rippled. Two hundred year old glass has a distinctively undulating surface. You can use this knowledge to tell how old some antiques are, and how old the glass in the windows are on some buildings. Taken to its extreme, if you had a large cup made of stone which could be left undisturbed, if you put pieces of smashed glass into the cup and left it there, if you could come back in a million years, you'd find the glass had flowed and taken a form like ice frozen from liquid water.[/QUOTE]
