A bstract Slips prepared in certain ways with some organic compounds shrink only slightly after casting so that their shape and porosity are not lost on drying or later firing. This provides a possible method of producing refractory insulation without final sawing to shape. The compounds effective in producing such porous clay bodies are certain amines or other organic cations, in which one or more large hydrocarbon groups are attached to the basic nitrogen atom. The results of studies concerned with molding and other problems connected with production of insulating refractories by this process are given.
