[edit] Flowing

Should there be a mention of the urban legend that glass flows?

There is one in the glass page, but I'll make mention of it in this article.--Polyparadigm 02:00, 16 Feb 2005 (UTC)

[edit] Ice

ice is a hydrogen bonded molecular crystalline solid Ice is an amorphous soli Acegikmo1 14:41, 17 Sep 2004 (UTC)

I've removed it, along with other substances that I'm fairly sure aren't amorphous solids, from the article. Acegikmo1 00:13, 17 Oct 2004 (UTC)
Ice does have several amorphous phases Jdrewitt (talk) 19:20, 15 December 2007 (UTC)

[edit] Glass: substance or another word for amorphous solid

The article is a little confusing because it contains several inconsistent definitions of the word glass. In the first half of the article it refers to a liquid that is cooled below the [glass transition temperature]], but in the second half it refers to common glass this page sucks!!!!!!!!!

Some liquids have a glass transition temperature that is higher than the melting point. This means that you can create a glass without supercooling the liquids. Therefore the following sentence is wrong

Tg cannot be greater than the melting temperature. Above the melting temperature, the substance is an isotropic liquid with a viscosity well below that of a glass. ---Dan Miller —Preceding unsigned comment added by 67.188.147.13 (talk) 22:08, 2 December 2007 (UTC)

"Glass is often referred to as a 'super-cooled' liquid.". glass is called a super cooled liquid because of its ability to flow in heating.It is also called a pseudo-solid However it is correct to write that "Some substances can only be cooled below the glass transition temperature if they are supercooled."

[edit] The definition

amorphous solid is a solid in which there is no long-range order of the positions of the atoms. (Solids in which there is long-range atomic order are called crystalline solids.)

Should we write "an amorphous solid is a solid in which the position of the atoms is in short-range order without long-range order"? Roscoe x 13:31, 16 Nov 2004 (UTC)

amorphous solids are solids having short range order.
