We present the results of quality factor measurements for rod samples made of fused silica. To decrease the dissipation, we annealed our samples. The highest quality factor that we observed was Q = (2.03 ± 0.01) × 108 for a mode at 384 Kz. This is the highest published value of Q in fused silica measured to date.
