Given a collection of minimal graphs, 𝑀 1 , 𝑀 2 , , 𝑀 𝑛 , with isothermal parametrizations in terms of the Gauss map and height differential, we give sufficient conditions on 𝑀 1 , 𝑀 2 , , 𝑀 𝑛 so that a convex combination of them will be a minimal graph. We will then provide two examples, taking a convex combination of Scherk's doubly periodic surface with the catenoid and Enneper's surface, respectively.
