1

is a hard, amorphous (non-crystalline) supercooled material made by melting sand, lime (calcium oxide) and sodium oxide at very high temperatures.

glass

2

is amorphous solid because its atoms are arranged in a random fashion. ►It is this irregular atomic structure that makes a variety of fractue patterns when glass breaks.

glass

3

However, by its nature, glass is usually ____because this material is found everywhere.

class evidence

4

silica SiO₂) are products that generally form the framework of the glass structure and when cooled quickly after melting they solidify without crystallizing

former agents

5

e.g. Na₂O) are components that are added to the formers to lower the melting temperature and to reduce cost of production

fluxes

6

e.g. CaO) are added to make glasses stronger and durable

stabilizer

7

Base or key component of commercial glass

Silica (SiO2)

8

Acts as flux for silica to lower its melting temp

Soda (Na₂O)

9

Acts as flux

Potash (K₂O)

10

Present as impurity or substitute for CaO as stabilizer

Magnesia (MgO)

11

Gives the glass excellent thermal resistance and durability, but makes glass more difficult to melt and shape

Alumina (Al2O3)

12

glasses, contains lead oxide that makes the glass sparkle as light passes through it.

leaded

13

contains Boron to provide heat resistance, and

borosilicate glass

14

The main raw materials utilized for the manufacture of soda lime glasses are

silica/sand, soda and lime

15

►Stronger than ordinary glass ► Strengthened by annealing during its manufacture ► When broken, this glass does not shatter, but fragments breaks into small squares ► Used in side and rear windows of automobile.

tempered glass

16

cracking pattern when glass is not pierced

spider web

17

In the event of breaking, it is held in place by an interlayer, typically of

polyvinyl butyral

18

it does not have a good large-area of orderly crystalline structure. If it did, it would be like metal steel, where it dents and deforms instead of shattering.

glass is brittle
