A titania-doped quartz glass containing 3-12 wt % of titania at a titania
concentration gradient less than or equal to 0.01 wt %/.mu.m and having
an apparent transmittance to 440 nm wavelength light of at least 30% at a
thickness of 6.35 mm is of such homogeneity that it provides a high
surface accuracy as required for EUV lithographic members, typically EUV
lithographic photomask substrates.
