Titania-silica glass body with identifying marker and methods of making thereof

Abstract

A glass body with a top surface, an opposing bottom surface, and one or more side surfaces. An identifying marker is on the top surface, the bottom surface, the one or more side surfaces, and/or within a bulk of the glass body, the identifying marker providing encoded information about one or more properties, characteristics, and/or compositional features of the glass body, and wherein a composition of the glass body comprises titania and silica. Furthermore, a peak-to-valley of hydroxyl concentration among a plurality of segments of the glass body is about 60 ppm or less, the hydroxyl concentration being measured using a Fourier transform infrared spectroscopy in transmission, and the plurality of segments including every adjacent segment across a length and a width of the glass body, the length being about 25 mm or more and the width being about 25 mm or more.
