"At the present time there are many insulating materials on the market. The temperatures at which these may be utilized vary from the lower temperature range of 100 degrees C, to a high temperature range of 2800 degrees C. Those insulating materials falling in the class of low temperature insulators have very little usage in commercial manufacturing processes therefore they will not be discussed in this paper. Materials that have a range from 600 degrees C to 2800 degrees C are of vital importance to the manufacturing processes. It is this type of material which we will endeavor to discuss here. Among the high temperature insulating materials we have the refractory and non-refractory materials. The non-refractory materials may be subdivided into groups according to their temperature ranges, however diatomaceous earth is the most important of the non-refractory A discussion of this material, whose properties are similar to all non-refractory materials, will disclose the principle of operation of the non-refractory group"--Insulating Materials, page 1.
