Abstract: A method of providing locally annealed regions for a glass article. The method includes providing a strengthened glass article having a first surface compressive stress and a first depth of layer of compressive stress, annealing the strengthened glass article to achieve a second surface compressive stress and a second depth of layer of compressive stress, and masking a portion of the glass article during the annealing step to achieve a third surface compressive stress and a third depth of layer of compressive stress in the masked portion. The glass article can be a laminate structure comprising a first glass layer, a second glass layer, and at least one polymer interlayer intermediate the first and second glass layers. The glass layers can include differing surface compressive stresses depths of layer of compressive stress.

Abstract: A laminate structure having a first glass layer, a second glass layer, and at least one polymer interlayer intermediate the first and second glass layers. In some embodiments, the first glass layer can be comprised of a strengthened glass having first and second surfaces, the second surface being adjacent the interlayer and chemically polished and the second glass layer can be comprised of a strengthened glass having third and fourth surfaces, the fourth surface being opposite the interlayer and chemically polished and the third surface being adjacent the interlayer and having a substantially transparent coating formed thereon. In another embodiment, the first glass layer is curved and the second glass layer is substantially planar and cold formed onto the first glass layer to provide a difference in surface compressive stresses on the surfaces of the second glass layer.

Abstract: Disclosed are cement compositions for applying to honeycomb bodies. The cement compositions can be applied as a plugging cement composition, segment cement, or even as after applied artificial skins or coatings. The cement compositions generally include an inorganic powder batch mixture consisting essentially of inorganic particles having a particle size greater than 100 nm. The cement compositions can further include an organic binder, a liquid vehicle, and one or more optional processing aids. Also disclosed are honeycomb bodies having the disclosed cement compositions applied thereto and methods for making same.
