"In the formation of dry pressed ware, the transmission of pressure is of vital importance to the quality and character of the finished product as regards the resistance to spalling, load at high temperatures, slag action, abrasion and other physical properties. Furthermore, the transmission of pressure is a limiting factor as regards the size and irregularity of shape of a product manufactured by the dry press process. Prior to the time of this investigation several companies have succeeded in producing ware up to six (6) inches in depth; but an increase over six inches has resulted, in every case, in failure due to lamenations sic , soft centers, and air cracks, which were caused by entrapped air...The Ceramic Industries of the United States have decided to conduct a series of investigations concerning the dry press problems of manufacturing bigger and better ware. So the National Brick Manufacturers Association have appointed a Committee on the Dry Press Process to work in coordination with the Ceramic Department of the Missouri School of Miens and Metallurgy on a series of investigations relative to the important problems of the dry press process"--Introduction, pages 3-4.
