A method for producing a high silicate glass substrate, includes: (1) obtaining a glass precursor containing, as represented by mol % based on oxides, 60% to 75% of SiO.sub.2, 0% to 15% of Al.sub.2O.sub.3, 15% to 30% of B.sub.2O.sub.3, 0% to 3% of P.sub.2O.sub.5, and 1% to 10% in total of at least one selected from R.sub.2O and R′O; (2) applying first heat treatment to the glass precursor to cause phase separation so as to obtain a phase-separated glass; (3) applying acid treatment to the phase-separated glass to make the phase-separated glass porous so as to obtain a porous glass; (4) drying the porous glass so that a rate of change in mass reaches 10% to 50%; and (5) applying second heat treatment to the porous glass to sinter the porous glass so as to obtain a high silicate glass substrate.

A method for winding up a glass ribbon is provided, in which, prior to winding up the glass ribbon, the two surfaces of the glass ribbon are each initially treated with a water-containing medium and subsequently dried so as to produce a defined content of water molecules on the two surfaces, by achieving a saturation of the surfaces of the glass ribbon with water, without bringing about an excess of water molecules. A glass roll is produced in which the electrostatic charge of the glass surface is reduced and, as a result, any undesired excess adherence of the glass surface to an interleaf material is prevented and, in this way, glass breakage, in particular during winding up and/or unwinding of the glass roll, can be markedly reduced.

The present invention provides a cover glass that can be installed in an automobile so as to cover a display unit including a plurality of information areas, including a glass body that has a first surface facing the display unit side, and a second surface opposite to the first surface, and that includes a plurality of transmission areas respectively corresponding to the information areas.

An apparatus and a method for continuously manufacturing tempered glass are provided. The tempered glass is continuously manufactured by transferring the raw glass in one direction, spraying a boiled potassium nitrate solution to the raw glass to reinforce the raw glass, and recovering and reusing the potassium nitrate solution from the raw glass. This invention can reduce the time to manufacture tempered glass since you can manufacture tempered glass consecutively, and the cost of purchasing potassium nitrate solutions can be reduced, which has an economic advantage. Since the raw glass is preheated, strengthened and annealed by divided sections of preheating, strengthening and annealing section in one furnace, it is less likely that impurities will be attached to the raw glass due to low external exposure during each process movement, thus preventing deterioration of quality.
