Abstract
Methods for preparing glass structures include extruding a glass precursor, the glass precursor having a composition in the range of 55%-75% SiO2, 5%-10% Na2O, 20%-35% B2O3 and 0%-5% Al2O3, and heat treating and leaching the glass precursor to yield a glass article comprising at least about 90% SiO2 by weight. Glass articles can be used to manufacture a variety of geometrically complex structures.
