The present disclosure relates to non-metallic articles that can be burner shields having grease flow control and/or chemical resistance. The present disclosure also relates to glass-ceramic burner shields that can have grease flow control and/or chemical resistance, and preferably both.

A glass sheet used in the making of an aircraft windshield is shaped using the “cut-to-size” method instead of the “cut-after-bend” method. In a preferred aspect of the invention the “cut-to-size” method is practiced using a bending iron having a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position.

A method for producing long-term bendable glass material includes: bending a glass material in a bending radius in a range of 1 mm to 10.sup.7 mm; storing the bent glass material for a time period of at least 1 day; inspecting at least a portion of the bent glass material for damage after the storing; and classifying the inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.

A method for shaping an optical element includes heating a first surface of an optical element, and allowing the first surface of the optical element to cool, thereby causing residual stress in the first surface which deforms the optical element to a predetermined shape. Heating can include applying a laser to the first surface.

The present application relates to a method for fabricating a vehicle interior trim part. The proposed method comprises the step of providing a glass panel with a backside and a first and a second region. In a further step, a first stiffener is attached to the first region of the glass panel. Thereby, a stiffened region of the glass panel is formed. The method further comprises the step of bending the second region of the glass panel by cold forming so that a bent region of the glass panel is formed in a region adjacent to the stiffened region. The method further comprises the step of holding the glass panel in shape using a means of fixation.

A glass sheet used in the making of an aircraft windshield is shaped using the cut-to-size method instead of the out-after-bend method. In a preferred aspect of the invention the cut-to-size method is practiced using a bending iron having a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position.

The present invention relates to a foldable glass sheet having a thickness t of equal to or smaller than 0.2 mm and having a surface compressive stress CS of greater than 700 MPa, in which when the glass sheet is subjected to a bending test in which, while bending and supporting the glass sheet by a first support board and a second support board which are parallel to each other, the second support board is moved relative to the first support board by equal to or greater than 200 mm in a state of maintaining an interval between a support surface of the first support board and a support surface of the second support board, the glass sheet is not broken even in a case where a curvature radius of a bent portion of the glass sheet is set to equal to or smaller than 10 mm.

A multi-layer glass enamel is disclosed. The various layers of the enamel are included to provide certain performance characteristics to the enamel. The components of each layer can be individually adjusted to tailor the performance characteristics influenced by that layer without changing the influence of the remaining layers.
