The 16" Turtleback lamp

All glass pieces have been into right shape
and some of them are framed with Copperfoil
alreay. The Turtleback band is cut from larger
Turtlbacks. That´s the reason for diffrent sizes
of those glass pieces.
 

Here you see the light table in reflected light.

The Turtleback pieces are cut "by hand"
No grinding machine was used here, same
technique workers at Tiffany Studios did.
