摘要： A glass processing method comprising steps (i), (ii) carried out in the order mentioned. In step (i), a laser pulse (11) with a wavelength λ is condensed by a lens and is applied to a glass plate (12) to form an altered portion (13) at the portion, irradiated with a laser pulse (11), of the glass plate (12). In step (ii), the altered portion (13) is etched by using an etchant having an etching rate larger for the altered portion (13) than that for the glass plate (12). The laser beam used includes the following conditions: The pulse width of a laser pulse (11) ranges from 1ns to 200ns, with a wavelength λ being up to 535nm. The absorption coefficient of the glass plate (12) at a wavelength λ is up to 50cm-1. A value obtained from a lens focal distance L (mm) divided by the beam diameter D (mm) of the laser pulse (11) when entering the lens is at least 7.

摘要： A vacuum glass panel including a vacuum glass, a sash, and a grazing gasket is provided. The vacuum glass includes a first glass plate, a second glass plate having substantially the same area as the area of the first glass plate in a front view, and a depressurized layer arranged between the first glass plate and the second glass plate opposed to the first glass plate. The lower face of the first glass plate and the lower face of the second glass plate are misaligned relative to each other in the vertical direction. The sash includes two groove walls that define a groove for receiving the upper, lower, right, and left peripheral edge portions of the vacuum glass in a front view. The grazing gasket is arranged on at least the lower portion of the vacuum glass inside the groove and seals a gap between the vacuum glass and the groove walls, and includes a clamping portion for clamping the vacuum glass from a first outer principal surface of the first glass plate and a second outer principal surface of the second glass plate near the top portions of the groove walls.
