Glass is a sustainable, fully recyclable material which provides great environmental benefits such as contributing to climate change and saving natural resources. It is also highly appreciated in many applications for its inert nature and its contributions to safeguarding people’s health ad well being.​ 

  • Mitigate climate change - In many of its application glass can help to save energy

  • Saves natural resources - Glass is a fully recyclable material that can be recycled over and over again. Glass is a resource efficient material and is made of natural raw material such as sand and glass waste. 

  • Safe-guard people's health and well being - Glass guarantees that food and beverages placed in glass containers are not stained by the packaging. It is also commonly used in the pharmaceutical industry to preserve the properties of medicines. In construction as well, architects not only use large glazed areas for their energy-saving properties but also because they provide natural light into buildings which enhance living and working conditions of occupants.

Glass blowing is the practice of shaping a mass of molten glass by blowing air into it through a tube. When the glass is still hot, the molten glass can be blown into a mold or shape. We see this process being utilized to create a new aesthetic and functional objects such as vases, bowls, plates, candlesticks, light fixtures, cups and so much more. Hand-blown glass does not have the machine-made symmetry and precision of manufactured, machine-produced glass objects. A hand-blown glass piece may have slight imperfections, irregularities, or even a slightly asymmetrical form. These sort of characteristics, however, give hand-blown glass its distinctive charm, though some glassblowing studios set aside their most irregular or imperfect pieces for sale at a lower price.

The best way to explain this incredible material that we call glass can be best explained in one sentence: "The history of glass is swathed in tales of mystery, secrecy and the quest for power." When discussing blown glass specifically, this is a process that gives people a lot of opportunity to create something miraculous. Blown glass is unique in the way that it can be blown and shaped into a variety of different forms, making each and every design distinct from one another. Because this tactic allows glass to be molted into so many different shapes and forms, we see glass blowing being used to create a lot of different functional items, and aesthetic ones too. We see this material being molted into cups, plates, bowls, and a lot of other items that we see and use in our daily lives. We also see this material being blown into art, where we can't help ourselves but to simply just observe and look at its true elegance and beauty that the artwork displays through its design. Take Figure 3 on the left, for example, where the glass blowing process turned this simple, transparent material into pure art. The colors presented in this sculpture are incredible, as well as the shape that this sculpture was molted into. Or take cups in figure 4 as an example too, where this functional item that we use daily makes drinking a glass of water just a little more interesting. The colors utilized throughout each cup makes each individual cup unique from one another, as well as the design that is displayed through each cup as well. 

The ATSM Glass standards are pretty elaborate, where a lot of testing goes behind this material in order to ensure that the standards of this material are met. Some of the tests that ATSM completes are listed below: 

 

  • C912 - 17 Standard Practice for Designing a Process for Cleaning Technical Glasses

  • C813 - 20 Standard Test Method for Hydrophobic Contamination on Glass by Contact Angle Measurement

  •  C676 - 04 Standard Test Method for Detergent Resistance of Ceramic Decorations on Glass Tableware

  • C777 - 04 Standard Test Method for Sulfide Resistance of Ceramic Decorations on Glass

Aside from ATSM, there are numerous organizations too that focus on testing glass, where a few of well known organizations are listed below: 

  • National Glass Association 

  • Contemporary Glass Society 

  • Society of Glass Technology 

  • Glass Axis

The image on the left is one example of glass blowing being utilized in a space. Not only do these light fixtures give the space a contrast of shape and color, but also brings functional light into this space. The maintenance requirements for blown glass are important to know before purchasing a blown glass item.  Below are some handy tips to keep in mind when taking care of glass blowing materials: 

  • Use a damp lint-free cloth to wipe glass art after dry dusting

  • Thicker items can be washed gently in lukewarm water with neutral soap

  • Do not use ammonia, cream cleaners or any harsh chemicals to clean shiny glass art. Aggressive detergents like so can damage the surface and leave an irreversible patchy, cloudy or milky effect

  • Cream cleaners can be used on sandblasted glass to remove some scratches or marks

  • After washing dry your artwork thoroughly with a soft cloth because minerals in water leave a residue which can damage and leave spots on the glass art
