When you look at modern glass windows, you never see the glass become thicker at the bottom. It does not flow. Consider the characteristics of liquids and solids. We have shown that the red molecule communicates only with a select group of neighbours shown in blue. But the behaviour of viscous liquids is more surprising than simply having to wait a long time. Share Flipboard Email. The glass transition Glass is so poorly understood that if a transition occurs it is far from universally accepted.

Probably the idea that glass is a liquid came from observing old window glass, which is thicker at the bottom than at the top.
Make up your mind, glass. Examples include a block of wood, a piece of coal and a brick. It is a solid. This gives the appearance that gravity may have caused the glass to slowly flow.

Molecules in a viscous liquid. Helmenstine holds a Ph. The mechanical properties, such as stiffness, of these glasses are superior to normal metals.
Liquid Glass is a flow-coating for protecting and repairing transparent / (REACH Annex II).
Is glass a solid or a liquid
Flammable liquids, Category 3. H Trade name: SONAX Clear Glass 3, H; STOT SE 3, H Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust) .
But the behaviour of viscous liquids is more surprising than simply having to wait a long time. Glass is an amorphous form of matter. On cooling we cannot definitively say yet that glass has become a solid.
The reason people thought glass might be a liquid was because old glass windows were thicker at the bottom than at the top. Regions of a few tens of molecules in size are liquid-like, others are solid-like.
It is a solid. Understanding the behaviour of glass-forming materials and whether there is a true solid glass is important in the development of metallic glasses.
