<p>The present invention relates to a new glass material applicable in those situations where thermal and/or mechanical shock would limit the use of other glass materials, presently available. Dopants are deposited into the interconnected pores of a porous glass in a non-uniform manner such that upon consolidation and cooling the final article has its surface under compressive stress. Dopants may also be added to control color and other appearance features.</p> |
