<p><P>PROBLEM TO BE SOLVED: To provide a transparent glass pane for a stove, and a method of manufacturing the transparent glass pane formed of transparent crystallized glass, having dome-like curved surface shape with the radii of curvature in a short-side direction and a long-side direction, having good surface properties and low in cost. <P>SOLUTION: This transparent glass pane 12 for the stove is formed of Li<SB>2</SB>O-Al<SB>2</SB>O<SB>3</SB>-SiO<SB>2</SB>-based crystallized glass withβ-quartz solid solution crystal precipitated in glass, and has the dome-like curved surface with the radius of curvature in the short-side direction being 150 mm or more and with the radius of curvature in the long-side direction being 500 mm or more. In the manufacturing method, the Li<SB>2</SB>O-Al<SB>2</SB>O<SB>3</SB>-SiO<SB>2</SB>-based crystalline glass pane is disposed on a shape face 11a of a shape 11 and heated at 850°C or higher to be softened and deformed along the shape face 11a of the shape 11, and theβ-quartz solid solution crystal is precipitated in the glass to form the transparent glass pane 12 for the stove. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
