The patterning on the surface of the Geologie Table Lamp takes great skill to create because it is glazed while it is on the wheel, which requires steady hand-eye coordination. Made of porcelain in a mix of beige, pale gray, and brown, the body of the lamp sits atop a metal base in an antique brass finish. A finial in the same finish fastens the textural shade to the lamp, which echoes the darker tones where the body meets the base.
