Description
UV radiation absorbing glass compositions, articles, and methods of making the same Technical Field The present invention relates generally to UV radiation absorbing glass compositions, glass articles comprising the same, and methods of making the same. Background More than 5,000 years ago, humans learned how to make glass articles. Modern uses of glass are very broad, including commercial and consumer uses. Glass is commonly used in commercial and technical applications related to the automotive industry, the electronics industry, spectroscopy, and the like. Often, glass articles are also exposed to a variety of environments, and in order to ensure long-term durability of the article, the glass composition needs to be designed to withstand such environments. For example, glass articles (e.g., container glass, window glass sheets, automotive windshields, laser matrix materials, fibers, tubing, etc.) are used in both commercial applications (e.g., bottles, jardinieres, artistic and craft glass articles, architectural windows, automotive windshields, etc.) and technical applications (e.g., glass tubes, glass fibers, laser matrix materials, etc.), often subject to environmental attack by moisture, with the result that their original properties are lost. Furthermore, glass containers are often used to hold items that are sensitive to UV radiation, and it is therefore important to form glass containers that are capable of blocking the transmission of such radiation that would otherwise affect the quality or performance of the items placed in the container. There is a need to develop commercially viable low UV light transmitting glass compositions based on the cost and processability of the glass melt. However, the addition of oxides that absorb UV radiation to soda-lime-silica glass (soda-lime-SILICA GLASS) can produce undesirable color shades. Thus, there is a need for glass articles that are reasonably neutral in color and have high visible light transmittance, and that contain a significantly lower amount of chemical or physical decolorant than is typically required to decolor low UV transmitting container glass. If desired, light-tinted, high visible light transmittance glass articles can be produced. These needs and other needs are at least partially met by the present disclosure. Disclosure of Invention In various aspects, the invention relates to a glass comprising about 0.09 to about 1.00 wt% cerium oxide, about 0.01 to less than 0.25 wt% iron oxide, about 0.01 to about 2.0 wt% zinc oxide, greater than 0 wt% to about 0.1 wt% titanium oxide, and wherein the glass is substantially free of erbium.
