Abstract
The present invention relates to a refractory filter comprising a plurality of filter elements formed from a refractory material having openings therein, said elements being arranged so that openings in one element are substantially staggered with the openings in another element, whereby the fluid path through the elements is tortuous characterised in that (i) the openings in each element are elongate, and (ii) the elements are arranged so that the openings in at least one element are offset with respect to the openings in another element.
