What are Willy Guhl planters made of?

Willy Guhl planters are made out of a variety of materials. For these furnishings, Guhl tended toward industrial materials, which he bent and shaped into organic forms for a striking juxtaposition. Much of his work was crafted from either concrete or Eternit, a mixture of cement and asbestos developed by the Belgian company Etex, which, in the 1950s, commissioned Guhl and his students at the School of Applied Arts to conceive Guhl's now-acclaimed planters in the material.
