The effect of occluded air in dry-press mixes

Author

William Raymond Powell

Abstract

"The effect of occluded air in clay mixes has recently become a subject of considerable importance especially since some of the defects occuring sic in dry-press ware, such as cracks and soft or granulated centers, have been either partially or wholly attributed to occluded air. According to this theory, the defects are due to the entrapping of air among the clay grains before compression, which, when the pressure is released, has a tendency to expand and cause a rupture in the bond. Also granulated centers have been explained by the fact that the entrapped air may act as a cushion, thus preventing intimate contact of the clay grains...The purpose of this investigation was to determine the effect of occluded air in dry-press mixes"--Introduction, page 1.
