How are glasses made

The manufacture of glasses can be broken down into three stages: acquiring the raw materials, shaping and grinding the materials, and making the finished product. The most common type of glass is clear but there are also colored and reflective varieties. Raw materials such as sand, soda ash and lime are usually bought in bulk and then combined with other ingredients in order to create specific types of glasses. For example, soda ash makes glasses hard while lime makes them flexible. Other substances may be added like copper oxide which helps to increase optical clarity or potassium nitrate which darkens lenses.
