Abstract
Textured samples cut from a vacuum extruded blank (50 wt.% kaolin, 25 wt.% feldspar and 25 wt.% quartz) were studied by a radiointroscopic method based on propagation of plane-polarized electromagnetic wave through a dry green sample as well as through the fired sample. The method is suitable for mapping the texture of large extruded ceramic blanks. A spiral character of the texture in the green hollow blank was revealed which has been found preserved even after high temperature firing.
