Glass Staining

The term ‘stained glass’ is somewhat of a misnomer as silver stain was not actually invented until the 14th century, long after the completion of many of the  famous medieval ‘stained glass’ windows of Chartres, Notre Dame and the other great 12th and 13th century cathedrals.


Silver stain is a combination of salts of silver with clay or ochre.  When it is fired onto base glass it will impart a yellowish stain ranging in colour from pale lemon through to deep amber.  The golden glow of silver stain is one of the delights of the art form and can add richness and complexity to the base glass.  It enables more than one colour to be contained in a single piece of glass, although this colour can only be a variation of yellow.
