 — The natural mirror grinding process will create a sphere. The first part of making a mirror is to grind and polish to a sphere of the required focal length. Then the mirror is parabolised, by using special polishing strokes, that changes the figure from sphere to paraboloid.

 — If you look at my video above, standard lapidary equipment is used to make marble size spheres. The grind is inside a hollowed out SiC grinder wheel and the pre-polish is using granite pades cut to fit inside of appropriately sized pipe fittings. A friend at my class claims as many as 10 per hour can be made of 3/4" size agate cubes.
