Abstract
An improved method for fabricating a ceramic sparger plate for use in the degassing of molten metal is disclosed in which a castable ceramic is poured into a mold which contains an array of vertically disposed strands which are removed subsequent to the ceramic curing and prior to firing of the ceramic thus leaving the desired pattern of holes through which the fluxing gas is introduced into the molten metal.
