Why Make Pottery Lamps
A pottery lamp base is a large, visible piece of functional art that people interact with every day. Unlike a bowl that lives in a cupboard, a lamp stands in the living room demanding attention. The scale and form of a clay lamp base give you an opportunity to make a bold artistic statement. And because each one is unique, a handmade pottery lamp becomes the defining piece of any room it occupies.
Stephen Jepson made pottery lamps throughout his career and considers them an underappreciated form. The throwing is straightforward — most lamp bases are tall cylinders or rounded forms — but the finishing and assembly require attention to detail.
Lamp Styles
Classic Table Lamp Base
A tall, rounded or cylindrical form — twelve to sixteen inches tall — with a flat top to mount the hardware. Throw it as a closed form or a tall cylinder. The base must be heavy enough to prevent tipping when the shade is mounted. The cord exits through a hole drilled in the base near the bottom.
Ginger Jar Lamp
A wide, rounded form — the classic ginger jar shape — with a narrow neck. This traditional form is elegant and substantial. Throw it in two sections if the size exceeds what you can throw in one piece. The wide belly provides a large surface for dramatic glazes or carved designs.
Carved Luminary Lamp
A hollow form with cutout patterns that allow light to pass through the clay walls. When lit from inside, the carved designs project shadows onto surrounding walls. Use a low-wattage LED bulb to avoid overheating. The effect is stunning in a dim room.
Slab-Built Modern Lamp
Geometric, angular lamp bases built from flat slabs of clay. Rectangles, triangles, hexagons — shapes impossible on a wheel. Slab lamps have a modern, architectural quality. The flat surfaces are perfect for carved designs or bold glaze graphics.
Making a Pottery Lamp Base
Throwing the Form
Use three to five pounds of clay for a standard table lamp base. Throw a tall, even-walled form. Leave the walls at least three-eighths inch thick for strength. The top should be flat or slightly domed to support the lamp hardware. Leave the bottom thick and heavy for stability.
Drilling for Wiring
At leather-hard stage, drill a hole near the base for the electrical cord — about three-eighths to half an inch in diameter. Drill a corresponding hole at the top center for the lamp rod. The rod runs from top to bottom inside the lamp, holding the socket at the top.
Assembly and Wiring
After firing and glazing, assemble the lamp hardware: a threaded rod runs through the center, secured with a nut and felt washer at the base. The socket mounts on top. Thread the cord through the base hole, up through the hollow interior, and connect to the socket. Use a rubber grommet where the cord exits the clay. A harp and shade mount on the socket.
Glazing and Finishing
Lamp bases are decorative, so glaze for visual impact. Rich, layered glazes that break over texture are stunning on large forms. Because the piece never contacts food, there are no food-safety constraints — use any glaze that fires well at your temperature.
