Abstract
Plates, which and be assembled and dismantled, are made from two refractory layers and a thin layer of, or contg. a carbonaceous material which decomposes or volatilises when heated to produce a layer of large pores between the layers of refractory material. This gives rise to increased thermal insulation in use, hence less tendency to produce pipe ingots or castings.
