Abstract
An improved method for the filtration of molten metal for use in the production of castings is disclosed in which a ladling crucible provided with a ceramic foam filter is inserted into a furnace crucible which is filled with molten metal so that the molten metal passes through the filter into the ladling crucible cavity so that oxide films and other impurities are removed prior to ladling.
