Project

The Schaubühne Lindenfels, built in 1876, presents two airy, perforated steel spheres resting on pedestals on the flat roof of its entrance side. The bodies, formed from triangles, allude to the Wilhelminian-era construction of the old society halls, and at the same time refer to no less than a building of the Vienna Secession with its golden sphere. A world-famous model, the implementation of which on the roof of the Leipzig Schaubühne had lost much of its original radiance over the decades and therefore needed to be restored and finished with, among other things, duroZINQ. The special feature: The steel spheres have a diameter of around two and a half metres when assembled.

Realisation

The art spheres were split into two hemispherical shells and processed in the shortest possible time thanks to careful planning of the entire machining process. After finishing with duroZINQ, the Leipzig team ensured the freshly galvanised hemispheres were stored flat, so that the delicate hollow body would not deform while lying down and could subsequently be coated with paint. And since the thin-walled steel antiques did not warp even one millimetre despite the zinc melt being around 450 degrees Celsius, everything also fitted together perfectly in its processed state – the restoration was therefore a success.
