I find the use of translucent porcelain in contemporary lighting exquisite. Delicate shapes and monumental forms take on a soft warm glow as they are illuminated from within the unglazed ceramic.
Here are two examples by a company called Diffuse that is based in the UK and owned by Jason and Lucy Boatswain. They slip cast their own porcelain and make pendants, wall lights, lamps and chandeliers. A lot of their pieces are custom designed like the chandelier shown (above), but there are many amazing stock designs to choose from as well (right).
The Cibola Pendant light by Scabetti (Dominic Bromley) is another striking example of how porcelain lighting can take on a sculptural quality.
