ABSTRACT:
A crystallized glass article formed of discrete small bodies of crystallizable glass fusion-bonded together at their interfaces is characterized in that a first layer extending from the article surface to a predetermined depth is non-porous, a predetermined thickness of second layer connected to and beneath the first layer being porous. Each of the small bodies in the first layer has needle-like .beta.-wollastonite crystals extending from the surface of the body to the interior thereof in a direction perpendicular to the surface of the body. Accordingly the article is characterized by a surface pattern defined by small bodies due to the differences of orientation of needle-like .beta.-wollastonite crystals and by a reduced specific gravity.
