Like most materials glass can be made with different characteristics, the ones you need to think about and know about are:

 Types of glass.
 * Brittleness
 * Transparency
 * Hardness
 * Unreactivity
 * Aesthetics.

 * <span style="font-family: 'Comic Sans MS', cursive;">Safety Glass ** <span style="font-family: 'Comic Sans MS', cursive;">is altered in such a way as to reduce the risk of personal injury to the end user and the public. There are two main types, [|toughened] and [|laminated]. Toughened glass is usually used where there is a high risk of impact and stress damage, as it is significantly stronger than plain glass. When broken, it disintegrates into small, relatively harmless, granular particles. Laminated glass is used for large panels where an element of security is required. Laminated glass is no stronger than plain glass but, due to the plastic interlayer, retains a high degree of structural integrity when damaged. Typical uses for toughened glass are: table tops, shelves, counter tops and panels, door and window glazing. Laminated glass is used in shopfronts, car windshields and high security panels. Both have limited applications in picture framing, but laminated glass can be produced to combat UV damage and, in very specialised forms, is widely used in Museums.
