Abstract: A method includes contacting a second layer of a glass sheet with a forming surface to form a shaped glass article. The glass sheet includes a first layer adjacent to the second layer. The first layer includes a first glass composition. The second layer includes a second glass composition. An effective viscosity of the glass sheet during the contacting step is less than a viscosity of the second layer of the glass sheet during the contacting step. A shaped glass article includes a first layer including a first glass composition and a second layer including a second glass composition. A softening point of the first glass composition is less than a softening point of the second glass composition. An effective 108.2 P temperature of the glass article is at most about 90° C.

Abstract: Embodiments disclosed herein include systems and methods for controlling material warp that include placing the shaped mold in a heating device, forming a glass material into a shaped mold, and cooling the glass material and the shaped mold to a predetermined viscosity of the glass material. Some embodiments include, a predetermined time prior to removing the glass material and the shaped mold from the heating device, holding the glass at the mold in the heating device where the heating device temperature is substantially equal to mold and glass temperature just prior to exiting to ambient temperature. Some embodiments include removing the glass material and the shaped mold from the heating device to further cool the glass material and the shaped mold at ambient temperature, where after removing the glass material and the shaped mold from the heating device, the glass material will exhibit controlled or desired material warp.

Abstract: A glass sheet is formed on a mold into a glass article having a three-dimensional shape. The mold, with the glass article thereon, is arranged within an interior space of a radiation shield such that the mold is between a leading end barrier and a trailing end barrier of the radiation shield. The mold, glass article, and radiation shield are translated through a sequence of cooling stations while maintaining the mold between the leading and trailing end barriers, wherein the leading and trailing end barriers inhibit radiation heat transfer at leading and trailing ends of the mold.
Abstract translation: 在模具上形成具有三维形状的玻璃制品的玻璃板。 其上具有玻璃制品的模具被布置在辐射屏蔽的内部空间内，使得模具位于辐射屏蔽的前端屏障和后端屏障之间。 模具，玻璃制品和辐射屏蔽通过一系列冷却站平移，同时将模具保持在前端和后端挡板之间，其中前端和后端阻挡件阻止模具的前端和后端的辐射热传递。

Abstract: Coated glass articles for a glass-ceramic ceramming process including a parting agent coated on a surface of the glass article. The parting agent coating can comprise an aqueous dispersion comprising amorphous silicon dioxide agglomerate particles and a dispersant. The parting agent coating can be dried to forming a parting layer for glass articles in a glass stack for a ceramming process that transforms the glass articles into glass-ceramic articles.

Abstract: Methods of forming a glass-ceramic article, the method are provided. Embodiments of the method may include initially nucleating a precursor glass composition at a first nucleation temperature and maintaining the first nucleation temperature for a pre-nucleating time period to produce a pre-nucleated crystallizable glass composition, wherein the pre-nucleated crystallizable glass composition comprises 5 wt % to 20 wt % crystalline phase ASTM C1365-18, forming the pre-nucleated crystallizable glass composition into an initial 3D shape; further nucleating the initial 3D shape for a nucleating time period to a second nucleation temperature to produce a nucleated crystallizable glass composition; and ceramming the nucleated crystallizable glass composition to a crystallization temperature and maintaining the ceramming temperature for a crystallization time period to produce the glass-ceramic article. The glass-ceramic article may have a final 3D shape is within 0.1 mm of the original design specifications.
