Step 1: Materials required
You also need a lamp socket, switch, and lamp cord. I found a candelabra cord at a building center that had all three items included.
The base for the lamp I built is the decorative cap from a ceiling light fixture.
You will need to cut a plywood disk that fits inside the ceiling light fixture cap. And, you will need two L-shaped screws (photo 3). I made my own screws by bending a 1/8th inch diameter copper rod and threading the long end for 6-32 threads. You will also need a couple of nuts to screw onto these L-shaped screws.
For an adhesive, I used high temp hot glue, but epoxy would work just fine as well.
The tools I used were a hot glue gun, soldering iron, drill and bits, and a rotary tool with grinding stones.
The candy jar will be inverted and placed on top of the ceiling light fixture part, and attached by using the two L-shaped screws to pull the inside shoulder of the jar against the base. I suppose you could just glue these parts together, but that would make it rather difficult to replace the light bulb in the future. By using the screws, everything can come apart with ease.
