Abstract: The invention relates to a glass composition of silica-soda-lime type colored blue which comprises the coloring agents below in a content varying within the following limits, by weight: Fe2O3 (total iron) 0.2 to 0.51% CoO 10 to 50 ppm Cr2O3 10 to 300 ppm CuO 0-400 ppm the glass exhibiting a redox factor of less than 0.35, a dominant wavelength ?D of between 485 and 489 nm, an excitation purity of less than 13% and a selectivity at least equal to 1.1 under a thickness of between 3 and 5 mm. It also relates to the glass sheet obtained from the abovementioned composition, said sheet being intended in particular to form an automobile window or for the construction industry.

Abstract: A high transmittance fairly clear/neutral colored glass composition is provided. An oxidizing agent(s) such as cerium oxide (e.g., CeO2) or the like is added to the glass batch in order to realize very oxidized conditions (i.e., to significantly lower the redox of the resulting glass). As a result of the oxidizing agent(s) used in the batch, the iron is oxidized to a very low FeO (ferrous state) content. For example, this may result in a glass having a glass redox value of no greater than 0.12 (more preferably <=0.10; even more preferably <=0.08; and most preferably <=0.05) and a % FeO (i.e., ferrous content) of from 0.0001 to 0.05%. In certain example embodiments, in order to compensate for yellow or yellow-green coloration a small amount of cobalt (Co) may be provided in the glass to enable it to realize a more neutral color.

Abstract: The present invention relates to: novel glass-ceramics of ?-quartz and/or of ?-spodumene; articles made from said novel glass-ceramics; and ithium alumino-silicate glasses, which are precursors of said novel glass-ceramics; methods of preparing said novel glass-ceramics and articles made from said novel glass-ceramics. The present invention relates to the use of SnO2 and of Br, as an agent for fining the glass-ceramic glass precursor.

Abstract: Method of joining at least two components (2, 3) utilising a fitting (1), where at least one of the components comprises, or is made of, a material which is difficult to weld. The components (2, 3) are provided with thicker walls at the end surfaces (6) that are to be joined. At least one of the thicker end walls is provided with an internal or external thread (T) and said at least two components are joined together by screwing said threaded end walls into and/or onto the fitting (1).

Abstract: The invention is a glass composition with high visible light transmission and low ultraviolet light transmission, comprising, in weight percentage, less than 0.03 wt % of ferric oxide, from 0.05 to 1 wt % of titanium oxide and from 0 to 0.6 of cerium oxide, the glass having greater than 87% in visible luminous transmittance; a UV light transmission less than 60% and more preferably less than 50%; and, a solar direct transmittance no more than 90%.
