Stained glass is coloured glass used to make decorative or pictorial windows and other objects that transmit light. In art history, the term usually refers to windows assembled from pieces of coloured glass, often held together by lead strips and painted for detail. The medium became especially prominent in medieval Europe, particularly in Gothic churches, but has been used in many settings and periods.

Definition and materials

Stained glass is coloured glass used for decorative windows and related objects. Colour is produced by adding metallic oxides or other compounds to molten glass, and finished panels are commonly assembled with lead cames.

History

Coloured glass objects existed in antiquity, but stained-glass windows developed in late antiquity and the early medieval period. Written evidence for figured stained glass appears by the second half of the 9th century, and the art reached major prominence in Gothic Europe.

Technique

Traditional stained-glass production begins with a design or cartoon, followed by cutting the glass, painting details, and assembling the pieces into a lead framework. The completed panel is fitted into a window frame.

Uses and themes

Stained glass was especially important in religious architecture because it shaped light and communicated stories visually. It also appeared in secular buildings and was used for decorative and symbolic purposes.
