Stained glass possesses an aura of mystery and romance. It is the interplay between light and color that sparks the imagination. It is one of the most unchanged crafts, still taking, as it did centuries ago: time and patience. Stained glass comes in three primary forms today: leaded, art, and faceted. The art-glass form was made popular by Louis C. Tiffany using colored enamels and iridescent glass.
