Table Luminaire by Muhammad Moussa. This signature collection of luminaires is made with low fire white clay shade and a solid hard wood base (maple or similar). Light is sculpted and softened by the ceramic shade creating a melange of reflection, shadow
I think what the artist did was use a circle mold and carved out the spaces when the clay was leather hard. It's an interesting technique because they look hard to do, but once you begin you get the hand of it, and they make cute candles.
