The invention relates to a method of casting a metal alloy ingot. The method includes providing an on one side open-ended mould having a mould cavity, positioning the open-ended mould such that the mould opening points side-wards or down-wards, providing a casting container with an upwardly positioned aperture, and filling said casting container with molten metal for one casting operation. The method also includes locating the casting container below the mould while the mould opening points side-wards or down-wards, and rotating the mould together with the casting container to a position whereby the mould opening points upwards such that the molten metal is conveyed into the open-ended mould until a desired thickness. Molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.
