Glass Artists Newsletter - May 2011

More Newsletters

You can read our current newsletter here on-line each month, free of charge. We hope you will take the opportunity to let your stained glass artist friends know about the newsletter and if you have students, encourage them to read it.

If you'd like a reminder when a new issue is published simply send us your e-mail address.

We are sponsoring a stained glass competition this month. Click here to learn about how to enter.

The show should be fun, if you can't enter, at least come and see it. The open house is on May 21st at our studio in Provo and the work will be on display thru June 18th.

The prize money is building as more folks enter!!!

Steve and Laurel live across the street from us. We hope that when folks visit the open house and competition they'll visit them to see the art piece they built.

We sandblasted a work of art that is going to a minister in Pennsylvania, who is moving on to another parish. The blasted figure of him is a pretty good likeness.

 
Last month we tacked the pieces of the panels together. Now, we're ready to solder the shade together.

Building A Stained Glass Lamp With A Worden Mold (Part 4)


 

”building

The assembly process begins once the 6 panels are tacked together. When lining up the first two panels, I line up the top and then a little farther down.

”building

Once I get the lower piece lined up, I tack solder it in place. 

”building

Then I move up to the top and line those pieces up. 

”building

Then as I move down the shade, I carefully and gently bend each side to meet each other.

”building

When they are lined up, I tack them together and then move on.

”building

When I can't get both pieces lined up, I line them up so that they are as close as I can get them.

In any shade, there are many places where pieces don't line up perfectly. As the lamp shade is built, it's normal to have imperfections since the flat pieces are laid out on a round surface.

”building

When I begin to line up the third panel, I squeeze and prod the panels to get them into place. 

”building

Just as before, I tack solder the pieces when I get them lined up. 

”building

Sometimes the entire panel needs to be bent, sometimes the pieces just need to adjusted.

”building

When the entire piece begins to feel a little wobbly, I add an extra piece to give the entire shade more support.

”building

As the sixth panel is put in place, the tacked in piece gets attached along one side first.

If you look carefully at the other edge you can see that it hasn't been aligned yet.

”building

When all 6 panels are tacked, I begin to tack in the pieces that were left out because they overlapped.

The tacked lampshade in very wobbly still and it remains so until the heat cap gets soldered in place.

I have to use care when moving the shade. By this time it is so heavy that pulling the shade carelessly will tear the copper foil.

”building

Once the heat cap is ready, I inspect the lamp shade and insure that the opening is round. 

”building

The heat cap has to be soldered to the top of the lamp shade. I can't put the shade up to check for balance yet, so I have to center cap visually. 

”building

When the cap is tacked in place, I was able to pick up the shade and turn it over. Since it's just tacked I have to be very careful. 

”building

When I place it into a box with paper for support, I can arrange to place more pieces into the shade. 

”building

As I began to work on the shade, it began to deform out of round. The box edges push too much on the sides. So I picked it up right away and set it on the table. 

It was easier to keep it round with the full support of the table.

”building

Once I got the missing pieces soldered in, I needed to strengthen the shade since the outside edge was very weak and placing it in a box would deform it. 

I solved the problem by gathering a drop cloth and using it to support the shade as I soldered it.

”building

I stood to solder at this stage. I soldered the very outside edge first, the bottom 4 inches of the shade. As I finished the space where the lines were on top, I would rotate the shade so the next couple of lines would be horizontal to the world.

I had to be careful when moving the base, it was easy to tear off an unsoldered piece of glass, so I picked up the shade from the outside bottom to rotate it.

”building

Once the outside ring at the bottom of the shade was soldered, it was strong enough to hold it's shape. I found that if I put the drop cloth in a trash can for additional support, it was the right size to support the shade as I finished soldering it.

”building

It took many hours, way too many (see note below), to complete the soldering of the shade and I got it complete on the outside but not the inside in time for our show.

      ”building   

The nearly finished shade was an important piece in our 2011 show at the Covey center entitled "Illumination". The piece with the shade represents "The Goddess Of The Vineyard."

Note: I have learned from past mistakes in the stained glass business that if you stop work on a panel and then pick it up again, you create a lot of work for yourself. There have been times when we have gotten a rush order, dropped the current project, completed the rush and then started back on the order we pushed aside. We have learned that it always takes so much more time to get back into the rhythm of the work (remembering what we'd done, what the colors were, etc.) that we would have been better off if we would have finished the work when the rush came and spent more time after-hours on the rush rather than dropping the original work.

This was particularly true with this shade which we worked on in our spare time over the course of a year. I tacked the panels together and assembled them, ran out of solder and didn't get back to the lamp shade for several months. The shade was left, un-cleaned for those months and when I went back to the finish soldering, I was dismayed to find that the time to finish the soldering was easily seven or eight times what it would have been if I had finished it all at once. I had to really work the old solder to get the new stuff to stick and the resulting lines were okay but not as perfect as they would have been had I done it all at once. In fact, I haven't done the second grape shade that all the pieces are cut and foiled for because it's just so labor intense that no one can afford the shade. So this is a method I may abandon.

The work you spend on a lamp shade
is worth it, like building a ship in a bottle.


I'm more and more interested
in lighting as we complete the
grape lamp shades.
