We report a significant improvement of the finesse and quality factor of a calcium fluoride whispering gallery mode optical resonator achieved with iterative thermal annealing. The initial and final values of the resonator finesse are F(i) approximately 5 x 10(5) and F(f) >/= 10(7) respectively. The measurements are conducted at room temperature in the laboratory atmosphere.
