      Material
        DescriptionA series of four iron stands made in a similar way by the twisting and bending of a simple iron bar. The bar is bent into a circle shape in its middle section with its two ends tracing a parallel path before turning 90 degrees in opposite directions, to after a short stretch be attached to disk-shaped feet.

        In all but the bottom-right stand, at one of their ends the bar then bends 180 degrees to come back to the point where both ends diverged and is soldered there to the other end of the bar.

        In the bottom-right stand one of the ends simply finishes near the point of divergence and is soldered there to another piece made of a bar bent 180 degrees that follows a similar path of the other end of the bar but does not end in a disk but simply one last right angle turn before the 180 degree bend.
