This invention is directed to a method for treating the surface of photothermally crystallizable chemically-machinable glass-ceramic articles to render them non-sticking when brought into contact with certain organic materials. More particularly, the invention is drawn to the treatment of photothermally crystallizable, chemically-machinable glass-ceramic head pads for use in conjunction with information storage discs with SO.sub.2 vapors to render them non-sticking with respect to those discs.

Surface treatment of photothermally crystallizable,

A composite glass article for channel plate fabrication comprising a glass matrix in which is encased an array of leachable glass core elements, the core elements being composed of a BaO-B.sub.2 O.sub.3 -SiO.sub.2 glass exhibiting improved leaching characteristics as well as thermal expansion and high temperature softening properties compatible with the glass matrix, is described.

Composite glass articles for channel plate fabrication

The instant invention relates to the production of composite glass articles involving the bringing together of two or more glasses, while in the molten state, into an integral unit. More particularly, the present invention is concerned with the manufacture of such articles wherein a reaction occurs at the interface between the laminae of molten glass such that an opal phase is spontaneously produced in situ thereat.
