Breton Stained Glass

Vitrail Breton

Antique mouth-blown glass cut to cartoon, painted in grisaille (iron oxide) and silver nitrate, kiln-fired, and assembled in lead came. The Gothic cathedrals of Brittany house some of France's finest medieval glass; Saint-Just is one of the last glasshouses producing authentic antique blown glass.
