Floral Stained Glass Lamp Repair

This lovely little lamp was brought to me by the same customer who had the prior lamp repair (click here).  She drove down from CT to see me in NJ on her way to PA.  Happy to be of service!

This lamp needed only 4 cracked pieces to be replaced.  Here are two, marked in blue tape ..


And here are the other two, also marked with blue tape.

The first step is to score the cracked piece with a glass cutter (shown). Then the piece is repeatedly tapped with the metal end of the cutter to loosen the glass.

Here the glass is nearly all removed.

The adjacent piece also needs replacement, but for the time being, I left it in place.

In the process of removing the larger cracked piece, an adjacent smaller one loosed.  Here I put it back in place after I applied new copper foil to its edges, and to the borders of the nearby pieces.

After the larger piece of glass was removed, I cleaned off the old solder and foil.  Then I traced a pattern as shown.

Using the pattern, I cut a new piece of green glass.  Here I'm using "groziers" to chunk out small pieces of glass along edges. This saves time at the grinder.

Then I apply copper foil along the edge of the replacement piece, as well as inside the borders of the dome where it will be soldered.

Now all three pieces have been replaced and soldered into place.  This is the view from inside the dome.

Moving around to the other side of the lamp, I've removed the piece of cracked glass which extends up to the border.

After making a pattern, cutting new glass, and preparing it, I've replaced it into the lamp as shown.

Here I'm applying black patina to the solder.

Soldering and patina-ing is complete .. Next I'll wax the lamp for protection and shine.

Here is one side of the lamp, repaired and ready to be enjoyed again.

And here is the other side, repaired. Thanks so much Sandhya, for bringing me two lamps to repair for you!

Art Deco Lamp Repair

This small lamp had cracks in two panels at the border, beneath decorative metal plates.  In order to repair it, I went in from the inside and removed and then replaced the cracked pieces.  Here's the process:

Notice the iridescent glass on this lamp, very pretty. 

The cracks can be seen best from the inside of the dome.  These two panels marked with blue tape required replacement.

I began by tapping on the cracked glass with the back of a glass cutter.  Then I removed the pieces of glass with needle nose pliers.

Next I pulled off the old copper foil and solder.

This is a Quoitzel brand lamp. Some of the older lamps made by this company are solid and well made.  This one, however is a newer lamp which was made in China.  The materials used to construct the lamp are somewhat suspect, and not of the quality of a true, soldered stained glass lamp.  To read more, please click this link ..  
Protective gear is mandatory on Chinese lamps such as these, simply because it is not possible to identify the black substance between the glass.  Here is my breathing mask, worn throughout the soldering process.

After I removed the cracked piece of glass, I cut a new one in the same type of glass.  Then I ground the edges as shown.

I applied new copper foil to the borders.  Here I'm pressing the foil onto the glass using a "fid".

After I placed the glass, I soldered it in place.

For added security, I added solder to the front of the piece as well.

Then I removed the adjacent cracked panel as shown.

The view through the "grating" or decorative border, with the glass removed.

Now both inside pieces that were cracked have been replaced.

And here is the finished lamp.  Thank you so much Sandhya, for stopping in with your two lamps from CT on your way to PA.  It was a pleasure meeting you! (Click here to see the repair of the second lamp).

Split Stained Glass Lamp Repair

This beauiful lamp sustained a separation along the dome which extended two rows down into other areas.  My challenge was to re-attach the pieces and reinforce them to prevent a recurrence.  Here's how I went about the repair ..

A light leak is evident just below the thick solder line near the top of the lamp.


Here's another view a bit closer.  The split extends down one row, then moves to the right, affecting 4 of the rectangular pieces of glass.

 At this point, I wedged my soldering iron into the separation and melted out the old copper foil and solder.  The piece which is marked with a Sharpie pen was very loose so I removed it.  This gave me better access to the split area and to the other 3 pieces of glass.
 Here's a view from inside the dome with the loose piece removed.

Here I'm in the process of removing more of the old solder and copper foil

I've cleaned up the old adhesive which were along the split, then I applied new copper foil to the piece I removed and to the three adjoining pieces of glass.  Here I'm applying liquid flux to the foil.  This is a liquid agent which allows the solder to flow smoothly on top of the foil.
 Now the pieces are firmly soldered in place.
 In order to prevent the split from re-occurring, I cut a few short lengths of flat braided copper reinforcement wire as shown, then I "tinned" them.  This means that I gave each side of the wire a thin coating of flux, then a dot of hot solder which flowed over and through the braiding.  This solder will bond with the lamp when its in place.
 Next I foiled, fluxed and soldered along the separated portion of the lamp as shown.

In the original construction, wires were placed along the solder lines with the intention of preventing the separation. However, the zig-zag decision proved to be ineffective on the side which split.  That small straight portion gave the lamp a good half inch of "play".  This side held well, the other side (which I'm repairing) did not.

 To reinforce that zig-zag, I soldered on a strip of the flat braided copper reinforcement wire as shown.  This effectively makes the zig-zag a straight line, giving the lamp more stability with much less chance of separation.

Then I used four more lengths of flat braided copper reinforcement wire and soldered them from the pale area of the lamp to the dark area.  This distributes the weight of the lamp around the dome and gives extra security that another separation cannot re-occur.

Here I'm applying black patina to the solder.

Then I clean the lamp of all flux and patina by using Kwik-Clean spray as shown.  After the lamp dries, I applied stained glass finishing compound, which is a light wax.  Once the wax dried and was buffed, the lamp is as good as new again.

And here's the repaired lamp, ready to go for many more years of service.  Thank you so much, Elizabeth, for bringing your lamp to me.  It was a pleasure to repair it!

Lamp Cap Repair

This lamp was made by my customer's dad.  Over time, the cap disconnected from the dome.  Here's how I went about repairing it ..

Here's a photo of the almost disconnected cap ..

A view of the lamp.  As you can see, the small cap is being asked to support quite a bit of weight.

My first step was to remove the cap entirely.  Then I melted out the old beads of solder around the edge.

Next I melted off as much of the old solder as I could.  This is a good quality brass cap, which is a "heat sink", meaning that it draws a lot of heat out of the iron.

I asked my husband Eric to use his sanding drill bit to remove more of the old solder.  Here the brass is clean and shiny, so it will adhere much better to the solder and the dome.

Many older lamps have un-grinded edges on the glass.  This lamp was no exception.  I took the time to use a hand file to smooth down the sharp glass. This makes the glass easier to handle and allows copper foil to bond more securely.

To give this cap added staying power, and to distribute the weight of the dome more evenly, I decided to add in three segments of flat braided reinforcement wire, shown here.  To prepare it, I applied liquid flux to the flat wire, then added a thin film of solder to both sides.  This process is called "tinning."

Then I attached the three strips of tinned reinforcement wire as shown.  When I applied the soldering iron to the strips, they bonded with the fresh solder beads that I added earlier.  Note that I also added new copper foil to the interior of the dome's opening.

Eric assisted me on this one, by soldering the outer edge of the cap to the dome.  The solder dots fused with the brass and the copper foil for a good bond.

As seen from inside the dome, he melted the flat reinforcement wire into the solder lines of the dome, then extended them onto the interior of the brass cap.  Then he melted on a generous amount of solder to assure that the three contact points will be firmly attached.  This creates a very strong bond between the cap and the dome.

After the soldering was complete, I applied black patina to all of the solder, inside and outside the dome.  After it dried, I applied stained glass finishing compound.  This is a light wax which protects the patina.

And here is the repaired lamp.  Thank you Geri, for entrusting your dad's lamp to my care.  I hope you and your family will enjoy it for many years to come!
