A good quote from Angier:

"Apart from a few exceptions -- mentioned hereafter -- the appearance of the finished parts corresponds to that of the un- browned surface: highly-polished surface thus retain a brilliant finish, dull ones a correspondingly non-reflecting coating. The mechanical preparation (polishing, etc.) of the pieces thus postulates the necessary attention: the greater the care taken in this respect the better the final result." p. 4-5
