| 20090266111 | Method of Producing Glass - Provided is a method of producing a glass, including, in order to obtain an excellent refining effect: preparing a raw glass batch including: an antimony compound containing pentavalent antimony; and an oxidizing agent (a cerium oxide, a sulfate, a nitrate); and melting the raw glass batch. In preparing the raw glass batch, it is preferable that the antimony compound be premixed with the oxidizing agent. When the nitrate is used as the oxidizing agent, the raw glass batch is prepared so as to include the antimony compound in an amount of more than 0.5 parts by mass and at most 3 parts by mass, in terms of an amount of antimony pentoxide, per 100 parts by mass of a base glass composition expressed in terms of an amount of an oxide. | 10-29-2009 |
