Molten metal is deposited on a movable plate in an inert atmosphere in a chamber and the plate is tilted, rotated and/or otherwise moved to distribute the molten metal to produce an art form. The metal is cooled sufficiently to solidify the art form and then various surface areas of the art form are subjected at selected elevated temperatures to chemical reaction with a selected reactive gas or mixture of gases to produce corresponding surface colorations in the various areas of the metal art form.
