A greenware precursor is disposed between a greenware base and a greenware cover. A frame is disposed between the greenware base and greenware cover for limiting compression of the greenware article to an amount which allows formation of a smooth ceramic surface during densification of the greenware precursor. The greenware base, greenware cover and greenware precursor are densified to cause the greenware precursor to form a ceramic having a smooth ceramic surface.
