the stages that glass go thruogh to make it glass?

The strict materials definition of glass is a uniform amorphous solid material produced when a suitably viscous molten material cools very rapidly not giving enough time for a regular crystal lattice to form.\nNormal glass like in a window is made from mostly silicon dioxide.\nMany different manufacturing processes, the most used is the float or annealing process.

Depending on it's composition, it can have a melting point of about 1400-1600 °C. However, there are glasses that will melt at lower temperatures but those are not common among commercial nor industrial usage.

It's called vapor deposition.  Sublimation is when a solid goes directly to gas.

The main constituent of Flat Glass is SiO2 (silica sand). This has a high melting temperature in the region of 1700 degrees C and its state at this temperature is like syrup on a very cold day.\nFor practical and economic reasons, the high melting point and viscosity of silica is reduced by adding sodium oxide (a flux)

You're going to have to elaborate some more.  What is a Newton's Glass?

Answer 1:\n"Glasses" are amorphous solids, that is, they don't have a regular shape.\nEssentially the opposite of crystalline solids which have a defined shape.\nWhen you break a crystalline solid, it will give flat, well defined faces.\nCrystals melt or decompose at definite temps and the change from s to l\nis usually abrupt.  Glass (say window glass) will shatter into irregular\nfaces and curves.  There are many different kinds of glass and none really\nhave a melting point.  All pretty much have silicon dioxide as a principle\ningredient then something else added:  Here are some numbers...keep in mind\nthese are all SOFTENING  points and NOT melting points:\nsilica glass: 1580 Celsius   soda-lime glass: 695 C\nborosilicate glass: 820 C    aluminosilicate glass: 915 C\nleaded glass: 630 C\nWhat I'm trying to say is:  glass isn't a liquid.  It's a solid with so\nmany 'defects' that the order inherent in a crystal is absent.  When I\nsay defects, I'm talking at the molecular level, not physical scratches,\nand so on. You may want to recheck that 100 K number you presented.\nThat's 173 degrees Celsius below zero (-280 F)!\nAm I going to get some arguments about my stance?  I'll find out more\nfrom our resident glassblower here at the university.\n-Joe Schultz\n\nAnswer 2:\nI very much agree with J. Schultz's response...  Here are a couple\nof other observations:\nGlass is formed by melting silicon dioxide (SiO2) which has a\nmelting point of 1710 deg. C..  In its crystalline form, SiO2\nhas a very ordered structure with each Si atom bonded to 4 O atoms\nand each O atom attached to two Si atoms.  If the SiO2 is quickly\ncooled after being melted, the SiO2 "molecules" do not have a chance\nto get completely lined up in their solid crystalline form and thus\nan amorphous solid (glass) is formed.\nOften we like to categorize substances as gas, solid, or liquid..\nobviously, glass is somewhere between a solid and a liquid --\nsome scientists refer to it as a pseudo-solid\n-Dr. Brown

well its all part of the process of making glass. When blowing glass it is heated to the point of flexibility........almost into a liquid form. The colors and swirls are formed during this state. Marbles are rolled to be solid, thus why the different "demensions" can be seen inside the marble. At times you can see an air bubble. Whites and colors come from the different colors added during the heating process. Just as they make glass beads. Go to Venice, Italy! Its amazing to watch. :)

Some Dude is right. Nowadays glass panes are made by pouring the glass over a basin of molten metal, mostly tin. In earlier days there were no fancy ovens like that, and glass was blown by means of a pipe into a bulb, that was made as large, and therefore as thin as possible. Next the lower half was cut off, and the remaning half sphere was whirled around  until it became an almost flat circle. This was the pane of glass from which smaller panes were cut, and the place where they broke of the blowing pipe forms the alleged nipple. Most of the 'nippled' panes you see however are not that old, they are seen as a nice antique twist to a new house that makes an impression of being old and original.

Child Of Glass (I think)

It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom.  This is not true.  In Mediaeval times panes of glass were often made by the Crown glass process.  A lump of molten glass was rolled, blown, expanded, flattened and finally spun into a disc before being cut into panes.  The sheets were thicker towards the edge of the disc and were usually installed with the heavier side at the bottom.  Other techniques of forming glass panes have been used but it is only the relatively recent float glass processes which have produced good quality flat sheets of glass.\n\nTo answer the question "Is glass liquid or solid?" we have to understand its thermodynamic and material properties.\n\nThermodynamics of glass\n\nThere is still much about the molecular physics and thermodynamics of glass that is not well understood, but we can give a general account of what is thought to be the case.\n\nMany solids have a crystalline structure on microscopic scales.  The molecules are arranged in a regular lattice.  As the solid is heated the molecules vibrate about their position in the lattice until, at the melting point, the crystal breaks down and the molecules start to flow.  There is a sharp distinction between the solid and the liquid state, that is separated by a first order phase transition, i.e. a discontinuous change in the properties of the material such as density.  Freezing is marked by a release of heat known as the heat of fusion. \n...\nConclusion\n\nThere is no clear answer to the question "Is glass solid or liquid?".  In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid.  The difference is semantic.  In terms of its material properties we can do little better.  There is no clear definition of the distinction between solids and highly viscous liquids.  All such phases or states of matter are idealisations of real material properties.  Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to every day experience.  The use of the term "supercooled liquid" to describe glass still persists, but is considered by many to be an unfortunate misnomer that should be avoided.  In any case, claims that glass panes in old windows have deformed due to glass flow have never been substantiated.  Examples of Roman glassware and calculations based on measurements of glass visco-properties indicate that these claims cannot be true.  The observed features are more easily explained as a result of the imperfect methods used to make glass window panes before the float glass process was invented.

both will have a miniscus and this is due to the adhesive property of water. the cohesive property keeps the water molecules togherter but the adhesive props allow for movement as in a cappilary tube. the gLass is clearer than the plastic so im thinking glass

Glass is made from silica and sand, heated at very high temperatures.  Different colors come from adding different metals and other elements.

I worked for a manufacturing plant that supplied this type of glass to it's vendors. We called it "micro-sheet glass".  It came to us in pizza shaped boxes, with many sheets per box. Very thin stuff. It came in different thicknesses. Some as light and thin as a sheet of paper. There were many steps involved in manufacturing these parts before they actually left the plant. As far as if they cracked, I am not sure about how it would be replaced. But am sure there must be another type of protection for that.

It cant be just any piece of glass, it has to be a prism. The light comes out in the form of a rainbow because the prism separates the light into it's visible colors.
