Abstract: A glass comprising titania and silica is disclosed. A plot of average hydroxyl concentration of each segment of a plurality of segments vs. distance along the glass is provided by: y=Ax2+Bx+C, wherein A (in ppm/mm2) is in a range from about 0.0 to about −0.1, B (in ppm/mm) is in a range from about −10 to about 10, C (in ppm) is about 450 or less, y is the average hydroxyl concentration (in ppm), and x is distance (in mm) such that the hydroxyl concentration of each segment is measured using a Fourier transform infrared spectroscopy in transmission and the plot extends a distance of about 50 mm or more along the glass.
