Abstract: Methods for regenerating poisoned salt bath comprising providing a salt bath comprising at least one of KNO3 and NaNO3, providing an ion-exchangeable substrate comprising lithium cations, contacting at least a portion of the ion-exchangeable substrate with the salt bath, whereby lithium cations in the salt bath diffuse from the ion-exchangeable substrate and are dissolved in the salt bath, and selectively precipitating dissolved lithium cations from the salt bath using phosphate salt. The methods further include preventing or reducing the formation of surface defects in the ion-exchangeable substrate by preventing or reducing the formation of crystals on the surface of the ion-exchangeable substrate upon removal from the salt bath.

Abstract: According to one embodiment, a method of manufacturing a glass article having a three-dimensional shape includes heating a glass article blank to a temperature above a setting temperature and coupling the glass article blank to an open-faced mold. The open-faced mold includes a molding region that has a three-dimensional shape that generally corresponds to the shape of the glass article and has an anisothermal temperature profile within the molding region. The method further includes maintaining an anisothermal temperature profile along the glass article blank and cooling the glass article blank while the glass article blank is coupled to the molding region of the open-faced mold to set the shape of the glass article.

Abstract: A method of forming a 3D glass article from a glass sheet includes locating the glass sheet on a mold assembly including a mold surface with a 3D surface profile corresponding to that of the 3D glass article. The glass sheet is heated to a forming temperature. The forming temperature is greater than a temperature of the mold surface. The heated glass sheet is forced onto the mold surface by applying a pressurized gas to a first surface of the glass sheet opposite the mold surface to conform the glass sheet to the mold surface with the glass sheet at the forming temperature that is greater than the temperature of the mold surface.

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 placed on a mold and heated to a first temperature. The glass sheet is then formed into a glass article having a three-dimensional shape using the mold. An isothermal heat transfer device comprising at least one heat pipe is provided in thermal contact with the mold. With the glass article on the mold and the isothermal heat transfer device in thermal contact with the mold, the glass article, mold, and isothermal heat transfer device are transported along a thermally-graded channel to cool the glass article to a second temperature. During the transporting, the isothermal heat transfer device transfers heat from a relatively hot region of the mold to a relatively cold region of the mold.
