Custom Clear Diamond Stained Glass Windows

I recently completed a pair of custom designed clear diamond stained glass windows.  The project began with a simple sketch which my customer made in my notebook. Her vision was realized with with two 36" x 16" windows which my husband Eric installed above their bar.

Here's her sketch.  Her idea was to have 4 bevels in each corner, with the center being clear yet opaque glass diamonds in the center.  We decided that clear glue chip would be a good choice for the center area.  She loves gray, so I proposed several different textures of clear gray to complement the glue chip.  


Here's my computer rendition.

After we met and decided on the general design I mailed several glass chips so she could choose favorites.  The "winning" choices were gray Waterglass for the outer border, gray Rough Rolled glass for the bevel rows, and clear glue chip for the center.

Here I'm preparing the pattern.  Its a three layered process.  The bottom layer is Manila folders taped together.  The middle layer is carbon paper. And the top layer is the "cartoon" or original pattern.  To the right, you'll see a small representation of the patterns for both the top and bottom windows.  I use these for reference as I work.

 The outside border is cut with standard scissors.  The inner cuts are made with specialized, double bladed stained glass pattern shears.  They leave a thin strip of paper between each pattern piece.  This allows room for the copper foil which will be added later.


Cutting the pattern pieces.

I organize the pattern pieces in recycled envelopes, by glass.  "GC" means the clear glue chip .. "RR" is the gray rough rolled .. "WG" is the gray waterglass.

This blue "running pliers" snaps glass in a straight line after I've "scored" it with the purple glass cutter, also shown.


Tracing pieces of the gray.

Using the glass cutter at a 90 degree angle, with firm pressure, to score a piece of gray.


As each piece of glass is cut, I bring it to the grinder.  This makes the edges safe to handle and helps the copper foil to adhere. 

Now all the glass is cut for the top window. There is a "fence" or metal enclosure around the window which is tacked into my work surface with push pins.  This keeps the glass from shifting.  It stays on until I complete the "tack soldering" process.

Here's a close up of the glass.  There's a nice mix of texture with the bevel, the waterglass on the outer border, the rough rolled glass on the bevel rows, and the glue chip diamonds in the center.

Before I apply copper foil to the glass, I etch my name and date into a corner piece.  I use an electric Dremel tool.  The signature is very subtle, in the lower right hand corner.

Now I'm applying "black back" adhesive copper foil.  Copper foil comes in several widths and with 3 different colors on the adhesive side (copper, silver, black).  Since this window will be patina-ed in black, I'm using foil which is black on the inside.  If any of the foil can be seen through the gray or glue chip glass, it will essentially become invisible.

Using a "fid" or flat plastic wand to burnish the foil onto the edges of each piece of glass.  This prevents any chemicals from working their way underneath.


And here is the top window, fully foiled and ready for internal reinforcement.

Here I'm using thin bands of copper and inserting them randomly throughout the window.  These strips serve to strengthen the piece and are invisible after soldering.

Applying liquid flux to the copper foil.  This liquid is a catalyst which enables the solder to flow freely.

The blue tape marks where I've inserted the reinforcement copper strips.  Here I'm doing the "tack soldering" process whereby I add a small amount of solder to the intersections of the pieces to lock them in place.

At this point, the entire front has been tack soldered and the glass pieces are all locked together, so I've removed the metal "fence" from the border.  Here I'm sliding the "cartoon" from underneath the window, to protect it from the chemicals which will follow.

Next, I fully soldered the entire front.  

Then I clean off the flux and excess solder with "Kwik-Clean" Flux and Patina Remover.

Now I'm moving on to work on the bottom window.  Here I've traced out diamond patterns to cut from the glue chip glass.

Using running pliers to snap the straight scores.

Back to the top window again .. After it was fully soldered and cleaned, my husband Eric custom cut and installed a sturdy zinc metal frame around the perimeter as shown.

Now the top window is framed.  Eric re-installed the "fence" around the border so that I can solder it to the window.

Here I'm soldering the lead lines to the frame.  You can also see my signature and date etched into the glass.

After the frame is soldered to the window, the fence is removed.  Here I'm applying liquid patina to the solder.  It turns it black instantly.  After letting it set for a while, I clean off the excess using Kwik-Clean.

And here is the top window on my work bench. 

Back to the bottom window.  Here all of the glass has been cut.

And now each piece of glass has been foiled.

And now the tack soldering is complete so the pieces are locked into place to prepare for the removal of the fence.

Fence is off and I'm sliding out the "cartoon".

And now the bottom window is soldered and ready for framing.

And here's a composite photo of the top and bottom windows, taken outdoors.  You can see the corner bevels clearly as well as the levels of transparency with the various types of glass.
And here's a photo taken indoors, on a white board.
Soon after both windows were completed, Eric installed them in our customers' home, above their bar.  They love them!

Here's a night view ..

And here it is in the daytime.  Thank you so much for the photo, Leslie.  It was a pleasure creating these windows for you and Drew!  May you and your family and guests enjoy them for many years to come!

Custom Oval Stained Glass Window

This window was created on request from a customer in South Carolina.  At certain times of the season, the sun comes into his oval window, creating a glare on his computer.  I created this for him by using all opaque ("opalescent") glass.  This glass allows light to come through, but its more muted than see-through, or "cathedral" glass.

For an oval window, we generally make a site visit and prepare a template so that the stained glass window will fit exactly.  In this case, because of the distance, my customer prepared a template and mailed it to us.

After I received the template, I prepared over twenty combinations of colors in the palette he suggested. Here is the "winning" rendition, with the exception that he requested a cranberry red in place of the dark amber.


Using a light box, I made a duplicate of the original template.

Here I'm making measurements and tracing the existing lines onto the duplicate.

Tracing out the pattern pieces, numbers, and glass colors onto Manila folders using carbon paper and ball point pen.

Further work, preparing the Manila pattern which will be used to cut the glass.

These double-bladed pattern shears cut a thin strip of paper between each piece of glass.  This is to allow clearance for the copper foil which will be wrapped around each piece of glass.

I organize the pattern pieces into marked recycled envelopes, by color.

I've scored this glass along the line and now I'm tapping the metal end of the glass cutter to "loosen" the glass so that it will crack along the line.

Grinding the edges of the center circular piece of white glass.

These "groziers" are an invaluable tool for nipping off long thin sections of glass as shown.

I prefer to cut glass by hand, but in some cases I use an electric wet saw.  It helps conserve glass and is able to make cuts which are not possible by hand.

It would not be possible to cut these three pieces, in this configuration, by hand.

The amber pieces, traced onto the glass.

Red opal glass has become almost impossible to locate.  I was fortunate to have some on hand, and by coincidence, I had just purchased some from a vendor in Pennsylvania, not knowing that I would be using it the following week.  Shown here are "running pliers" which are used to snap glass which has been scored in a straight line.

More red opal being traced.

The glass still needs to be trimmed and properly fitted, but its all cut at this point.

The next step is to apply the adhesive copper foil to the edges of the glass.  Here I'm using a "fid" to burnish the foil onto the glass.

On each larger window, I always add reinforcement.  Here I've run a long strip of copper that fits between the glass.   It adds a great deal of strength to the window and also adds stiffness which will prevent cracks.

In order to be sure that the cut glass lined up perfectly with the template, I pinned and soldered the center area of the window first.

Here I'm etching my name, the month and year into the glass with an electric Dremel tool.

Continuing with the process of copper foiling.  I don't foil the edges of my stained glass windows.  They will be covered by a metal frame, so there's no need to do so.

Burnishing a red opal piece. Notice that the window fits perfectly onto the template now.  The small amount of clearance will accommodate the soft lead came frame that my husband will install later.

Applying liquid flux to the copper foil using a metal acid brush.  This chemical acts as a catalyst, allowing the solder to flow smoothly over the foil.  Next I solder the front of the window.


Here my husband Eric is attaching a flexible lead came frame to the oval.  He's taping it in place temporarily.

Now he's applying push pins around the border to hold it in place so that I can solder it to the lead lines.

Now I'm applying black patina to the solder. 

After it sets for a while, I has to be thoroughly cleaned off.

After the window is dry, I apply stained glass finishing compound to the front, back and sides.  Then I let that dry, and buff it off.

The window will look different depending on the light.  Here it is on top of a light box.

And here it is, lit from the front, on a white board.

This window is being shipped from New Jersey to South Carolina.  Here my husband is cutting plywood to use in shipping the window.  We double-box our windows, pack them securely with a few types of packing materials, and mark the outside with many "Fragile-Glass" stickers.  We also insure the windows and provide a tracking number to our customers.

We're happy to report that the window made it, safe and sound.  Our customer is very happy .. Here it is in its new home!  Thank you David, for entrusting me with this project, long distance.  It was a pleasure creating it for you!

Here's another view of the window.  We attached industrial-strength double sided tape to several points in the back so that David could easily do the installation himself.
