In general, glass is a hard and brittle substance that is usually transparent or translucent . It may be comprised of a fusion of sand, soda, lime, or other materials. The most common glass forming process heats the raw materials until they become molten liquid, then rapidly cools the material to create hardened glass.

What are the properties of glass and water?
Water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na 2 O) and silica (silicon dioxide, SiO 2 ) that forms a glassy solid with the very useful property of being soluble in water. Water glass is sold as solid lumps or powders or as a clear, syrupy liquid.
What are the disadvantages of glass?
- It is a very costly material and has to be handled with care.
- It requires regular cleaning. In high rises external cleaning and maintenance from can be very challenging.
- Extensive use of glass might result in both psychological and actual security concerns.

What does glass look like?
Glass is a non-crystalline, often transparent amorphous solid , that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring.
