The commercial value of high temperature thermal insulators is discussed, and a numerical example of a problem in designing a flue for conducting hot gases is given. A suggestion is offered for carrying out research in the manufacture of more highly refractory thermal insulators than are at present available, and tentative specifications for refractory and insulating properties are given. It is further suggested that refractory manufacturers should interest themselves in such research. The need of a simple apparatus, called for convenience a conductometer, for carrying out routine investigations of thermal conductivity, is pointed out, and, after describing some of the more important apparatus formerly used, a design of an improved new type is suggested and the method of working up the results is described.
