    摘要: An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material. Before the metal material filling the second corner C is solidified, the second metal introduction device 5B is moved from the second corner C toward another end of another third side Vbc, while performing filling with a metal material.

    摘要: The present invention provides a glass composition not requiring a large quantity of rare earth material, producible by a common apparatus for producing a glass, having a high Young's modulus and a large crack initiation load, and suitable for glass fibers etc. A glass composition according to the present invention contains, in mol%: 50 to 65% SiO 2 ; 7.5 to 26% Al 2 O 3 ; 15 to 30% MgO; 0 to 8% CaO; 0 to 3% B 2 O 3 ; 0 to 3% Li 2 O; and 0 to 0.2% Na 2 O. In this glass composition, a total content of MgO and CaO is in a range of 18 to 35 mol%, and a mol ratio calculated by Al 2 O 3 / (MgO + CaO) is less than 1.
