Shortly after we completed work on the kitchen cabinet replacement panels (see blog entries below), we began the next commission. This commission is for a pair of double-hung windows for a
bathroom which overlooks a patio.
For many years, the homeowners had used a stick-on faux stained glass window product. They decided it was finally time to put the real thing in its place. The homeowners requested that the glass used would allow for privacy, but also
light. They had a wonderful design
already in mind. They also had a deadline in mind, their upcoming family reunion. No problem! Here is their inspiration window: (Click on any photo to enlarge).
Together, we decided on a medium
amber rough rolled glass for the borders, light amber opalescent for the larger
triangles, medium green hammered Cathedral for the design, and clear granite
for the center diamonds. This
glass will provide light and privacy and the colors and textures
will add visual interest.
After deciding the design, glass choices and colors, the
next step is to prepare the pattern.
This is done by tracing it onto old manila folders using carbon paper as
shown:
Next, each piece of the pattern is cut using specialized
scissors which leave a small amount of “breathing space” between each piece, as
shown. This is to allow room for
the copper foil which will be applied later.
Its important to be very well organized with the pattern
pieces, especially when building two nearly identical windows. I labeled each piece “top” or “bottom”
and put them into recycled, labeled envelopes as shown:
When tracing the pattern onto glass which is textured, turn
the glass to the smooth side and turn the pattern face down. The glass is then scored using a glass
cutter. There are several kinds available. I prefer the pistol grip cutter as
shown.
As for cutting glass, there are several techniques to use,
depending on the character of the glass.
Generally speaking, Cathedral (or see-through) glass is easiest to cut. The more dense opalescent glass take a bit more care, sometimes a lot
more. But either glass can break
unexpectedly, so I always follow the rule, “The glass is the boss.”
Below, I’ve traced and scored the border glass. Since it uses about 1/3 of the total
12” x 16” sheet, and the cut is a straight line, I scored it and decided to
snap it off the edge of the table as shown. My left hand is resting on the “good” part, the part that
will be used in the window. Pressing gently down with my right hand (not shown), the glass broke cleanly and evenly across its entire length.
Another way to cut straight pieces, particularly shorter
ones is to use “running pliers” like the blue ones shown here. Tap lightly on the score line front and
back, using the metal end of the pistol grip cutter. Then line up the score line with the line on top of the
pliers and use medium pressure. If
the glass does not respond, tap some more and try again. Keep trying until it breaks.
There are also a few ways to trim off small pieces of
glass. One way is by using
“groziers” or special stained glass pliers as shown:
After several pieces of glass are cut, I take them to the
grinder and smooth all the edges. This is done not only for safety, but to
assure that the copper foil will adhere correctly.
Notice that I’m wearing fingertip protectors. They are invaluable when grinding cut
glass. They are available at any
Staples, in several sizes.
As each piece of glass is cut and ground, it gets laid onto
the pattern like a jigsaw puzzle.
Notice that the borders of the pattern are now contained with a metal
fence or “jig”. This assures that
all the glass stays in place throughout the process. The “jig” is released only after the glass has been tack
soldered. Here are both windows
with all the glass cut, inside the jigs.
The copper foil process is next. Each piece of glass is edged with adhesive copper foil. There are several widths of foil available. I used the most common size, 7/32” wide. Because these
windows will have a black patina, I used black-backed foil for the see-through
glass. Here are the windows, fully
foiled:
Next is the tack soldering. All of the copper foil is now brushed with a liquid flux as
shown, and soldered at the joints and key spots within the windows. When the tack soldering is done, the
jig is released and the paper pattern is slid out from underneath and set
aside.
Then the full soldering process begins. First the front, then the back of each
window. Safety first, I always
wear a Sperian P1130 face mask against any flux or fumes from the solder, which
is 60/40, tin/lead. The masks are
about $12 each and can be found in most hardware stores.
Here are the windows, fully soldered, front and back. You’ll note that I do not add copper
foil to the outer edges of the windows.
It sometimes interferes with the installation of the metal framing, so
it is best left off.
Here my husband Eric is fitting metal channel, or framing
material, to the borders of each side of each window. This adds strength and stability. It also assures that if the homeowners ever want to remove
the windows, they can do so.
Framing with metal channel adds considerably to the life of any stained
glass window.
Here are both windows, with the metal channel, back in the
jig so that I can solder the lead lines to the frames.
I solder the lead lines to the frame on the back of each
window. I also solder the mitered
corners, front and back.
After both windows were soldered and framed, I carefully
wash them with powdered cleanser and brush them in the sink. This is to remove the flux, beads of
solder, and any remaining marks made by the Sharpie during the assembly
process.
After the windows are dry, the black patina is brushed onto
the solder lines and the zinc channel frame, both sides.
It takes about 24 hours for the adhesive to set completely. Therefore Eric temporarily secured both windows by using corrugated cardboard blocks and blue painters tape. The homeowners had their own "big reveal" the next day, when they removed the blocks and tape!
In summary, here are the "inspiration" photo, the computer rendition of the finished windows, and the finished windows!
