Double-skinned copper bowl, fluted with wavy lines. Alex Brogden, 1992.
Materials and techniques
The top skin is made by first carving the fluted form from a large lump of wax. The geometry of this carving is made possible by using a combination of using wavy brass templates and pivoting cutting arms to guide the hand controlled cutting of the wax. A thick copper electroform is deposited onto the finished wax. The wax is then melted away and the surface of the copper filed, chased and polished. Patinated with brown bronze powder and then waxed with hard car wax.
