Abstract
In casting molten metal (e.g. aluminium and copper) a ceramic foam filter element 2 is disposed upstream of a casting mould cavity 5 so as to filter the metal which passes from funnel 1 through the filter element to channels 3 in non-turbulent flow, to remove oxide and prevent generation of new oxide downstream of element 2. <IMAGE>
