Stained glass

Stained glass is coloured glass used to make decorative or pictorial windows and other objects that transmit light.

Updated August 1, 20261 min readCited sources

Stained glass is coloured glass used for decorative windows and objects that transmit light. It became a major art form in medieval Europe, especially in Gothic churches.

What it is

Stained glass refers to coloured glass assembled into ornamental or pictorial windows. Colour is produced by adding metallic oxides to molten glass, and pieces are traditionally joined with lead strips called cames.

Why it matters

Stained glass shaped the atmosphere of Gothic cathedrals by filtering light into coloured patterns and telling biblical stories to a largely illiterate population. Surviving medieval examples remain important cultural and religious artefacts.

Key details

The technique developed in the 9th and 10th centuries. A design is cut from coloured glass, painted for detail, and assembled into a lead framework. Common subjects include religious scenes, saints, and heraldry.

In short

  • Stained glass is coloured glass used mainly for ornamental windows.
  • It became prominent in Gothic European churches between c. 1150 and 1550.
  • The craft uses cut, painted glass pieces joined by lead strips.
  • Stained glass also appears in civic buildings and private homes.
Canadian angle

Stained glass is relevant to Canadian readers through church architecture, historic public buildings, and the work of Canadian studio glass artists and conservators. It is also part of preservation efforts in Canada’s heritage buildings, where original windows are often repaired rather than replaced.
