Understanding glass art manufacturing techniques

Art glass is a product that is usually made for decoration as well as for other purposes. It is made from glass sculptured into a magnificent form. Various techniques are used in glass arts and these include leaded lights, stained glass window, placing the glass in a kiln to mould it into shape, sandblasted glass, glassblowing as well as copper-foil glasswork. In the recent past, there has been a rise in the popularity of art in glass. There also many artists who have become popular as a result of their work. There are also different arts in glass manufacturing techniques and these include:

Stained glass

Stained glass is commonly used for decoration purposes in church windows. This process begins by cutting the glass into shape. Paint containing ground glass is then applied. It is heated in a kiln to enable the paint to fuse with the surface of the glass.

Blown glass

This is one of the most popular techniques for manufacturing fine art glass. Many artists today prefer this method as it offers the artist some kind of intimacy with the glass as well as unlimited opportunity for variation and creation at every stage of manufacturing. It is possible to create a wide range of shapes and colors using glassblowing.

Kiln formed glass

This technique is also known as warm glass. It can be made of a single glass slumped into a mould. It can also be made of different sheets and colours fused together. Art in glass that is formed in kiln can take the form of plates, dishes and tiles. It is important for the glass fused in kiln to have a similar co-efficient of expansion (CoE). Failure to fuse using glass with the same CoE will cause formation of minute stress fractures and these may lead to formation of cracks. Polarizing filter can be used to determine whether there is formation of stress fractures.


It is possible to decorate glass using sandblasting. You sandblast the glass to get rid of one layer so that the design stands out. This technique offers a 3-dimensional effect. However, it is not the best method for the toughened glass as it could make it shatter.

Copperfoil technique

This method is used to manufacture the small pieces like the Tiffany style lamps. The cut part of the glass is wrapped using a self-adhesive tape made of a thin foil of copper. The foiled sections are soldered to create the item. The downside of this technique is that it can be time-consuming

With these and other glass manufacturing technique, it is possible to create some great glass designs.
