The manufacture of a lens element that is pure enough to be used for photography is pretty complex. You need materials with adequate purity, light transmission, and hardness, not to mention a fair bit of precision in your grinding mechanism to ensure you refract light enough to focus it where you want it focused, and do so evenly across the surface of the lens.

Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface
