I make both the stained glass lampshades and lamp bases. I don't currently have any lamps in stock for immediate sale but I am working on another leaf lamp that should be available soon. Let me know if you would like to commission a lamp.
My leaf lamps make use of the lead lines between glass pieces to represent the veins in leaves. The lamp pictured here is based on big leaf maple leaves, a tree that grows on the west coast of the US. The lamp bases for these lamps are made from manzanita burls that come from the deserts of the southwest.
I also make lamps where both the lampshade and base flare out at the bottom. This provide a beautiful aesthetic effect as well as improving the stability of the lamp. The lamp base is made from laminated wood. Four thin sheets of poplar are bent and glued together in a curved form so that they hold the curve when the glue is set. A fine hardwood veneer is applied to the surface.
In addition to glass, I also use sliced Brazilian agate to make lamp shades. The edges of the agate slices are wrapped in copper foil, as is done with glass pieces. But since the agate slices do not fit neatly together, the way properly cut and ground glass pieces do, this design also requires bridging gaps between the agate slices with copper foil and then building up solder to form a solid matrix to hold the agate pieces. The lamp base is made from wrought iron and walnut wood.
The third material that works well in lamp shades, becuase they also transmit light, is seashells. The underside of these shells has been cut off to improve light transmission and make them easier to attach to the other elements of the lamp
