WHAT IS STAINED GLASS?
There is a mystery to glass: It is a form of matter
with gas, liquid and solid state properties. Glass is
most like a super-cooled liquid. It captures light
and glows from within. It is a jewel like substance
made from the most ordinary materials: sandtransformed by fire. Before recorded history, man
learned to make glass and color it by adding
metallic salts and oxides. These minerals within
the glass capture specific portions from the
spectrum of white light allowing the human eye to
see various colors. Gold produces stunning
cranberry, cobalt makes blues; silver creates
shades of yellow and gold while copper makes
greens and brick red.
TECHNIQUES AND CONSTRUCTION
Techniques of stained
glass window construction were described by the
monk Theophilus who wrote a how to for
craftsmen about 1100 AD. It describes methods
little changed over 900 years: "if you want to
assemble simple windows, first mark out the
dimensions of their length and breadth on a
wooden board, then draw scroll work or anything
else that pleases you, and select colors that are
to be put in. Cut the glass and fit the pieces
together with the grozing iron. Enclose them with
lead camesand solder on both sides. Surround it
with a wooden frame strengthened with nails and
set it up in the place where you wish."THE GOTHIC AGE
The Gothic age produced the great cathedrals of
Europe and brought a full flowering of stained
glass windows. Churches became taller and
lighter, walls thinned and stained glass was used
to fill the increasingly larger openings in them.
Stained glass became the sun filled world outside.
Abbot Suger of the Abbey of St. Denis rebuilt his
church in what is one of the first examples of the
Gothic style. He brought in craftsmen to make the
glass and kept a journal of what was done. He
truly believed that the presence of beautiful
objects would lift mens' souls closer to GodStained glass windows are often viewed as
translucent pictures. Gothic stained glass
windows are a complex mosaic of bits of colored
glass joined with lead into an intricate pattern
illustrating biblical stories and saints lives. Viewed
from the ground, they appear not as a picture but
as a network of black lines and colored light.
Medieval man experienced a window more than
he read it. It made the church that special, sacred
dwelling place of an all powerful God.
We see medieval craftsmen
were more interested in illustrating an idea than
creating natural or realistic images. Rich, jewel
colors played off milky, dull neutrals. Paint work
was often crude and unsophisticated: A dark
brown enamel, called grisaille, was matted to the
glass surface to delineate features, not to control
the transmission of light.
Stained glass artists became glass painters as the
form became closer and closer to panel painting.
Lead lines that were once accepted as a
necessary and decorative element became
structural evils to be camouflaged by the design.
THE RENAISSANCEThe Renaissance brought the art of stained glass
into a 300 year period where windows were white
glass heavily painted. They lost all their previous
glory and it seemed the original symbolism and
innate beauty of stained glass was forgotten.
In the 15th century, the apex of high Gothic, the
way stained glass was viewed changed. It became

more a picture and less an atmosphere. Paler
colors admitted more light and figures were
larger, often filling the entire window. Paint work
became more sophisticated, more like easel
painting. The rediscovery of silver stain allowed
the artist to realistically depict yellow hair andgolden garments.
In this period, stained glass became a fashionable
addition to residences , public buildings and
churches. Heraldic glass showing detailed shields
and coats of arms on simple, transparent
backgrounds was common. Much of what stained
glass was became forgotten. The 18th century
saw the removal of many medieval stained glass
windows. They were destroyed as hopelessly old
fashioned and replaced by painted glass.
19TH CENTURY /RISE OF TIFFANY STYLE
England in the mid 1800s
saw a revival of interest in Gothic architecture.
Several amateur art historians and scientists
rediscovered the medieval glass techniques.
Pieces of glass were tested and their color secrets
unlocked.
Glass studios in England made their versions of
medieval windows for Gothic Revival buildings.
The Bolton Brothers, English immigrants,
established one of the first stained glass studios
in America. These Gothic style windows enhanced
churches and simple ornamental windows and
painted figural windows were the norm until thedevelopment of a distinctive American style.
John LaFarge and Louis Comfort Tiffany were two
American painters who began experimenting with
glass. Contemporaries, but working
independently, they were trying to develop glass
that possessed a wide range of visual effects
without painting. They soon became competitors.
LaFarge developed and copyrighted opalescent
glass in 1879. Tiffany popularized it and his name
became synonymous with opalescent glass and
the American glass movement. LaFarge and
Tiffany used intricate cuts and richly colored
glasses within in detailed, flowing designs.Plating, or layering glass layers, achieved depth
and texture. Both made windows for private
homes as well as churches.
The process of using thin strips of copper as a
substitute for lead came allowed for intricate
sections within windows. Tiffany adapted the
technique to construct lampshades and
capitalized on the new innovation of electric
lighting. Tiffanys customers were wealthy, turn of
the century families including the Vanderbilts' and
Astors. The Tiffany style prompted many imitators
and opalescent windows and shades remained
popular through the turn of the century.
20TH CENTURY AND BEYOND
Tastes
changed after WWI. A revival of archeological
accuracy in architecture called for new gothic
glass windows for the NeoGothic churches.
LaFarge had died in 1910, interest in opalescent
glass waned and Tiffany remained its last
defendant until his death in 1933 and the
subsequent bankruptcy of his studios. New
craftsmen such as William Willet, Rambusch,
Charles Connick and Nicolai DAscenzo, made
windows for churches across America.
Except for church windows, stained glass
remained in decline until the post WWII era. The
abstract and expressionist movement in painting
influenced a new group of artists to explore
artistic expression in the medium of glass.
Contemporary church windows may in some ways
be closer to those of the early Gothic period. Not

easy to identify scenes, they again create a pure
atmosphere of light and color, inspiring a
contemplative attitude through the transformation
of the ordinary into the mystical.
Stained glass,
or more appropriate art glass, is all around us
today. An explosion of interest toward the end of
the 20th century has given rise to many new and
imaginative forms of this art. The rise of the
individual artist, new technologies and the
growing interest in stained glass as a hobby craft
have all lead to what is being called A a new
golden age in glass. New homes are frequently
embellished with spectacular beveled glassentryways, stained glass bathroom windows and
Tiffany style lampshades. Decorative panels are
purchased just to hang in a sunny window.
Marvelous hot formed glass pieces adorn tables,
walls, shelves and fill windows. New artists are
combining, creating, and developing unique new
forms and styles every day.
