Description
During a solar eclipse, all that remains of the light is the halo. The disc in front is dark, and around it stands a narrow, glowing ring: the corona.
KORONA hangs this image on the wall. A disc of concrete sits in front of a second, larger one, and the LED light emerges only at the edge between the two. The surface stays dull, the rim glows.
Handmade from ultra-light concrete in France, the edge drawn by hand and therefore never perfectly round on any light. LED and cable are built in.
On the material
Materials You Can See and Feel
A room looks expensive or cheap long before anyone knows a price. The difference rarely lies in the form. It comes from how surfaces treat light: whether they reflect it, absorb it or scatter it.
That is why material is not a question of taste but a decision with consequences – for the look, but also for care. What each of the major materials can do and where it reaches its limits is set out here.
