The seams of the lamp shade have been copperplated now.

This is necessary for the patination.
 

Inside the lamp you can see a reinforcement wire here. It follows the seams

and isn`t visible  from outside, when the shade is lit.
 

There are running 6 reinforcement wires from the upper aperture rim to lowere border rim of the shade.

Another reinforcement is following the circumference of the shade in a distance of 1-4 inches

from it´s lower border.
