Unfortunately, I did not get photos of every step of the construction process. I do not have photos after the first level was soldered front and back, nor after the third level was added.

Disclaimer: I apologize for the poor quality of the photos. I was more intent on construction, not photography, not to mention the disruption of getting the flux off my hands in order to take pictures, and dead batteries in the camera and dead spare batteries...
 

Top level completed

The shade sits above the first level. The pull ring is made from 14 gauge wire wrapped around something that is .5” diameter.

Back side completed

In this photo, you can see the height of the sealed cells of the windows. The gaps between levels 2 and 4 where there were no level 3 elements was enclosed with 1/4” black-backed foil, then soldered over. If you look carefully, you may be able to see that the table top is one layer thicker than the table front. You can also see the Baroque on the third level, sticking up above the shadow and clear on level 2 of the vase.

Back side completed
(close up)

This closeup shows the depth of four layers of glass.

Back side after level 2 soldered in place

At this point, the seams are mostly tinned. You do not solder a bead until all the components have been installed.Otherwise, the layers will not fit snugly against each other.

Back side after level 4 soldered in place

Back side of panel after soldering is complete. It has been partially cleaned and patinaed, but final cleaning and waxing are still needed.
