What gives polished metal that ‘glow’?
A polished surface is really a surface so that is so smooth, it is shiny. Naturally, the surface is a microscopic mountain range, with the light reflecting into itself. Buffing smoothes that surface to the point the light reflects back, the ‘glow’ is derived from thousands of fine directional buff lines reflecting light back that is just slightly scattered, this gives fine polished metals that ‘illumination’.
