Do medieval churches and cathedrals come to your mind when you think of stained glass? Yes, stained glass has been around for thousands of years, right from 3rd or 4th century AD, especially used in churches, monasteries and cathedrals. Stained glass is also an integral part of Islamic architecture, especially in palaces and mosques across the Middle East.
Today, stained glass has made its mark in both industrial and residential architecture. It is now globally recognized by glass manufacturers and suppliers.
Stained glass is nothing but coloured glass used to make decorative designs that create a picture or tell a story. Normal uncoloured glass is made by fusing numerous raw materials like silica, an alkali and limestone or lead oxide. This raw mixture when heated at extremely high temperatures creates a new material called glass. Stained glass is made by adding metallic oxides to the raw mixture before heating it, to obtain the desired colours.
Since glass at high temperature is almost similar to a liquid, it can be poured, blown, or moulded into numerous shapes and sizes. For stained glass, this molten mixture is rolled into thin sheets, cooled and shipped to craftsmen to create stunning stained-glass artwork.
Possible Colours in Glass
Technological advances have now made it easy to produce glass in different colours under different conditions. Glass manufacturers use metallic oxides to make hundreds of tints, colour, and patterns in different textures, for shipping globally.
For example, copper oxide gives shades of red and blue. Iron oxide gives shades of bluish-green. While chromium will produce shades of green, titanium or uranium will produce golden coloured glass. Adding gold yields a rich ruby-coloured glass.
There are six basic steps in making stained glass. They are:
Decorative windows and domes made of stained glass can be commonly found in historic buildings.

Stained glass can last a lifetime and add incomparable beauty to any environment. Stained glass lets light in while still providing opacity. For modern architects and designers, stained glass inserts are the perfect choice for doors and windows, ceilings, entryways, skylights, partitions, dividers or cupboards, and even the bathrooms. Other than just houses, pubs, hotels, restaurants, corporate buildings, educational campuses, conservatories and greenhouses too incorporate stained glass in their architecture.
Nowadays, you will also find a variety of objects that are made of stained glass. For example, lamp shades, jewellery, ornaments, personal accessories, canister sets, bottles, figurines and a host of other decorative and fancy items.
To conclude, stained glass has been dazzling generations from time immemorial and is now transforming the future of architecture.
