Artisan Glass vs Commercial Glass

Artisan glass are one-off creations as opposed to commercial glass which is standardized 
and mass produced (such as glass windows). Before technology in the industrial period allowed such mass production, most glass products were considered artisan glass. Artisan glass are all individually crafted or handblown and can be decorative or serve a purpose

Examples of artisan glass include objects such as cups, paperweights, platters, sculptures, perfume bottles, wall art etc.
Manufacturing techniques include the following:
  1. Stained Glass
  2. Blown Glass
  3. Kiln-formed glass
  4. Sandblasting
  5. Moulding
  6. Cut glass
Glass decorating techniques including the following:
  1. Colour 
  2. Texture – frosting, sandblasting
  3. Surfaces: engraving, cutting
The Venetians in particular gained a reputation for technical skill and artistic ability in the making of glass bottles. The Egyptians made glass beads and bottles dating back to 1500BC. Middle age Europe saw popular use of stained glass windows espeically in religious buildings.
There are many options to colour glass by adding metal and metal oxides as well as minerals including oxide (brown), chromium (green), manganese (purple) etc.

Common glass these days are commercial glass. Commercial glass is widely used in the architectural industry in particular architectural glazing. Commercial glass include both float and value-added coated glass-products, such as tempered glass, low-emissivity (low-E) glass, mirrored and patterned glass, solar glass and insulating and reflective glass for a wide range of construction projects.
There are three types of commercial glass:
  1. Borosilicate – most resilient and able to withstand high tempertatures, used for testtubes and kitchenware
  2. Soda lime glass (float glass) – lack of colour, fairly durable, almost exclusively used for windows and jars.
  3. Silica glass – more delicate, thin and transparent. Used to make UV filters in eye glasses. Not good for containers but makes a decent window glass (but more expensive than soda lime windows)
There are two main methods to make commercial glass:
  1. The float glass process (produces sheet glass)
  2. Glass blowing (produces bottles and other other containers)
Commercial glass are produced in factories using various machinery such as forming machines and furnaces which form a production line.
