The metal employed in those early mirrors was an alloy of copper and tin, the usual proportion about 75 to 25, which could be given a beautiful polish. But the metal was highly challenging to function, along with a prodigious amount of labor was involved in grinding and polishing the curve. To facilitate the function, the comparatively thin disks had been cast to the approximate curve, the backs also becoming curved to give uniform thickness and equalization of temperature effects. Grinding was completed on convex iron tools of similar radius, working with emery, and from time to time sand. Polishing was done on a pitch lap, with rouge. Manufacturers normally devised their own machines to do the work of grinding and polishing. Except where the utmost perfection was imperative, figuring seems to have consisted for probably the most part of a final brief variation of the stroke, in an unguided attempt to concentrate the polishing at the center. Vital testing, undoubtedly seldom indulged in on account of its laboriousness, could as but only be performed on a star. In reflective capacity, speculum was only about 60 per cent efficient, and also the surface tarnished rapidly, effecting a further significant light loss. This meant frequent repolishing, and repolishing meant refiguring.
