Viscosity of various types of vitreous silica was measured by a cantilever-beam-bending method having been used in industry. The viscosity measured by this method agreed with the value measured by a standard beam-bending method for the same sample, and temperature dependence of viscosity are consistent with those reported in literature using various measurement methods. OH content dependence of the viscosity at 1200℃ was measured. There are two groups of vitreous silica, each of which can be represented the viscosity by a decreasing function of OH content; one group is fused quartz (FQ) produced by melting natural quartz powder, and another group is synthetic fused silica (SFS) produced by flame hydrolysis of SiCl_4. The viscosity of FQ is higher than that of SFS at the same OH content.
