…or to be exact Ferrocement Faux Bois in concrete. Yes, all of these pieces are indeed sculpted out of concrete! They are not wood. Faux bois is an art form that has been sculpted since the 18oo's in Europe. Faux Bois literally means "false wood" in French. But the French do not call it Faux Bois, they call it La Rocaille. Ferrocement means the addition of a steel frame or armature. This unique art has become a highly collectible art form because the artists that knew the techniques and formulas …have faded away into history.
