    Abstract: A transparent armor laminate system includes a plurality of sub-stacks separated by an interlayer. The sub-stacks include a plurality of layers including a glass ceramic front strike-face layer, a backing layer comprising a spall-resistant material, and at least one glass layer laminated between the strike-face and backing layers. The interlayer isolates cracks between sub-stacks, and may include an isolating material such as a polymer, gas, or liquid. The laminate system offers improved performance with reduced weight over conventional all-glass or all-glass-ceramic transparent armors.

    Abstract: The invention relates to opaque, colored glass ceramic articles and to the production of opaque, colored glass-ceramic articles which can be readily formed to a desired shape using standard metal-working tools. The glass-ceramic material used to make such articles contains mica crystals as the predominant phase. The desired color is obtained through the addition of a colorant system to the precursor glass. In a particular embodiment the invention is directed to a black glass ceramic article, the black color being obtained by the addition of iron oxides in levels as high as 20 wt%, which can yield a glass ceramic having an iron rice mica phase and/or a glass ceramic having an iron rich mica phase plus an iron oxide phase.
