<p>The invention relates to gray, bluish, blue to black colored borosilicate glasses which have a stepped transmission grade in the near infrared range or are fully non-transmitting. The borosilicate glass with defined additions of titanium dioxide is melted together with a reduction agent such as Si(metallic). The glasses produced in accordance with the invention are used as filters because of their absorption/transmission characteristic or, if the light transmissibility in the near infrared/infrared ranges is sufficiently low, the glasses can also be used as absorbers in solar technology, as a glass used in areas of the home and/or as decorative colored glass in construction and for decorating.</p> |
