This invention is directed to the preparation of alloy articles consisting essentially of glass and/or glass-ceramic and an organic thermoplastic or thermosetting polymer having a working temperature compatible with that of the glass and/or the precursor glass for the glass-ceramic. The glass and polymer are combined at the working temperature to form an intimate mixture; i.e., the glass and polymer are in a sufficiently fluid state to be blended together to yield a body exhibiting an essentially uniform, fine-grained microstructure wherein, desirably, there is at least partial miscibility and/or a reaction between the glass and the polymer to promote adhesion and bonding therebetween. A body is shaped from the mixture and cooled to room temperature.

Glass/glass-ceramic-plastic alloy articles

There is disclosed an integral vitreous article composed of an opacified interior portion encased within a surface layer of glass that is transparent except for an opacified zone of predetermined configuration. The article may be produced by momentarily contacting an exposed surface on a molten glass charge with a chilling member before forming the glass.

Glass article having a pattern formed in its surface and method

This invention is drawn to the production of thermally-tempered, transparent glass articles which are integrally colored to demonstrate a particular amber-with-rose-highlights hue. More definitively, the present invention is directed to narrowly-delineated glass compositions within the general Na.sub.2 O-CaO-SiO.sub.2 system having incorporated therein critically-limited amounts of NiO and MnO.sub.2 as colorants.

Colored soda-lime glassware

Photosensitive laminated glass useful for providing strong, lightweight glass articles incorporating integral surface decorations resistant to mechanical and chemical deterioration in use are described.

Strong, lightweight photosensitive laminate

An improvement upon the making of colored photosensitive glasses via the exposure thereof to high energy or actinic radiation followed by heat treatment thereof, the improvement comprising conducting the exposure of the glasses while such are at a temperature between about 200.degree. - 410.degree. C. to thereby considerably shorten the time required for developing color and to produce colors of very high intensity.

Process for making colored photosensitive glass

This invention is concerned with glass-ceramic articles having compositions within a very narrowly-delimited area of the MgO-Al.sub.2 O.sub.3 -B.sub.2 O.sub.3 -SiO.sub.2 field and having alpha-quartz and sapphirine as the principal crystal phases, resulting from nucleation through a combination of TiO.sub.2 and ZrO.sub.2. Upon contacting such articles with lithium ions at an elevated temperature, said lithium ions will replace magnesium ions on a two Li.sup.+-for-one Mg.sup..sup.+2 basis within the crystal structures, thereby providing a unitary glass-ceramic article having an integral surface layer wherein the principal crystal phase is a lithium-stuffed beta-quartz solid solution. That transformation of crystal phases results in compressive stresses being set up within the surface layer as the articles are cooled. Through the careful control of composition, crystallization treatment, and the parameters of the replacement reaction in the crystal structures, a tremendous degree of stored elastic energy can be developed within the articles such that they will demonstrate frangibility when fractured but will not exhibit undesirable spontaneous breakage and/or spalling.
