The provided is a method for manufacturing a disklike glass material comprising the successive molding of multiple pieces of disklike glass material from glass melt. Being suppressed variation over time in the concentration of infrared radiation-absorbing ions contained in the glass melt being molded into said pieces of disklike glass material so that the variation in the sheet thickness of said multiple pieces of disklike glass material falls within a range of ±15 percent of a reference value. The reference value being the median between the maximum value and the minimum value of the sheet thickness of 1,000 pieces of said glass material. In the course of molding multiple pieces of disklike glass material comprised of glass containing 0.1 to 100 ppm of infrared radiation-absorbing ions, variation over time in the concentration of the infrared radiation-absorbing ions contained in the glass melt being molded into said pieces of disklike glass material is suppressed to suppress variation in the sheet thickness of said multiple pieces of sheetlike glass material. | 01-21-2010 |

| 20100064728 | METHOD FOR PRODUCING IRIDESCENT CRYSTAL GLASS - The invention relates to a method for producing iridescent crystal glass. The glass products produced with the method of present invention have the advantages of good streamline shape, natural color transition, and excellent visual effect, etc.; the method is helpful for accelerating product upgrade, improving product appearance and visual effects, and enhancing competence of products. Therefore, we paint iridescent crystal ink on glass products, and add patterns suitable for household electric appliances and buildings, thereby greatly improving the appearance of the product. In addition, due to the high safety performance of toughened glass and suitability of patterns and colors, iridescent crystal glass products have been accepted by the consumers gradually. The method comprises the following steps: a. cutting; b. edge processing; c. toughening; d. ink preparation; e. iridescent crystal printing; f. drying: the drying time and drying temperature are controlled according to the properties of the mixed ink; the drying temperature is controlled at 120˜200° C., and the drying time is controlled within 5˜30 minutes. | 03-18-2010 |
| 20100139321 | SHEET WIDTH CONTROL FOR OVERFLOW DOWNDRAW SHEET GLASS FORMING APPARATUS - A method keeps the width of the manufactured sheet substantially the same by attaching edge directors for the formed sheet to the manufacturing apparatus structure instead of to the forming block. Thus, sheet glass may be manufactured to specification for a longer time with the same forming block. An additional method adjusts the width of the manufactured sheet by changing the distance between the edge directors. Thus sheet glass may be manufactured to different width specifications with the same forming block. | 06-10-2010 |
