Abstract
Adherent layers of glass are deposited on a preform or substrate via the controlled oxidation of a glass precursor, such as silicon monoxide, in the vapor state, thereby providing unusual shaped composite articles having a glass coating on the substrate. A preform or substrate such as carbon can subsequently be oxidized, thereby providing a glass microcapillary of exceedingly uniform dimensions.
