A1

In one aspect, the invention relates to a method of producing a porous body of refractory material having a predetermined configuration of pores, comprising : - (a) providing a plurality of porous body elements, each element being formed from a plastic refractory material and having a plurality of pores formed therein ; (b) assembling together the porous body elements to form a desired shape of porous body having the desired configuration of pores ; and (c) heating the assembled porous body elements such that they become fused together and lose their plasticity. In another aspect, the invention provides a porous body of refractory material having a predetermined configuration of pores (62) comprising a plurality of refractory body elements (60, 70) which are arranged in a stack and joined together to produce the predetermined configuration of pores (62). At least one of the body elements (70) is non-planar and preferably corrugated.
