studies in metal – the hyperbolic paraboloid
This is a study in moving metal – here the bronze was hammered with a specialized set of stakes and hammers to shape flat metal sheet into a sculpturesque structure. The form is known to mathematicians as a “hyperbolic paraboloid” which is a doubly ruled surface that is shaped like a saddle. It incorporates two planes that are formed in opposing directions – which gets increasingly difficult to accomplish if your medium is metal. Below you can see examples of traditional hyperbolic paraboloids that I have created with a planishing hammer and various stakes.
