Vintage Patinated Copper Diving Bell Seed Chamber

Construct a spherical framework using steam-bent white oak ribs to provide a sturdy, rounded skeleton. Secure the ribs to a central circular base plate to establish the structural foundation of the diving bell.

Apply thin, hand-cut copper sheeting over the wooden framework using decorative brass tacks. Allow the copper to naturally patina with a salt-and-vinegar wash to achieve an authentic, aged maritime appearance.

Install a thick, circular tempered glass porthole into the front face to serve as both an observation window and a weather shield. Seal the glass edges with waterproof marine-grade silicone to ensure the seed remains dry inside.

Mount a series of small, circular landing perches around the circumference of the base to provide ample access for birds. Finish the assembly with a heavy-duty forged iron chain and ring for balanced suspension from a tree branch.
