A method for treating a mold includes grinding an outer metal surface of a mold body of the mold with a first material; lapping the outer metal surface after the grinding with a second material that is finer than the first material; and polishing the outer metal surface after the lapping to achieve an average surface roughness (R) less than or equal to about 0.15 &#x3bc;m and a waviness height (W) less than or equal to about 100 nm. A mold for shaping glass-based material can include a mold body having an outer metal surface, wherein the outer metal surface has an average surface roughness (R) less than or equal to about 0.15 &#x3bc;m and a waviness height (W) less than or equal to about 100 nm.
