Emaux de Briare
The mosaic has been created entirely with Emaux de Briares, a type of mosaic made in France since 1845. The Emaux de Briare knew a great enthusiasm during the Art nouveau movement, as the trend was to ornate and color the entrance and facades of buildings. Nowadays they can still be spotted about on the streets, and its most notorious example might as well be St-Étienne Church in Briare.
