A method for forming metal articles, such as rods and tubes by aspiration casting is provided in which a hollow frangible mold, such as a glass tube, is immersed at one end in a molten metal bath, a vacuum is applied to the other end controlled with respect to temperature of the molten metal so as to substantially fill the mold with a minimum of turbulence, the filled mold is withdrawn from the metal and the frangible mold is shattered to remove it from the metal article formed within.
