摘要： In a process for liquefying glass batch and the like, wherein a layer of batch (50) is maintained as a lining in the liquefaction vessel (12), the thickness of the lining (54) is monitored by measuring the temperature in a region (66-68) facing an end portion of the lining. Preferably, a series of thermocouples (60-65) serves to determine the location of the face of the lining (66-68) on which liquefaction is taking place.

摘要： The present invention provides a glass composite transparency having a desired color, intensity and a high performance ratio. In particular, the transparency includes at least one rigid transparent ply, e.g. a colored glass or plastic substrate, and a member secured to a major surface of the substrate, e.g. a flexible plastic layer or a coating. The member has a color that generally complements the color of the glass substrate to reduce the overall intensity of the composite transparency. In one embodiment of the invention, the transparency is gray in color and has a performance ratio of at least 1.4, preferably at LTA ≧ 70%.

摘要： A clear glass, with the substantial absence of color in transmittance, and with an attractive, bright, pure azure edge coloration is achieved in a glass having greater than 87 percent, preferably greater than 90 percent, luminous transmittance by using very small amounts of iron oxide as the sole essential colorant, with the ratio of iron in the ferrous state to total iron being at least 0.4.
