If there is nothing else in the scene, there is nothing to reflect or refract.
Try placing some objects off field. You may want to use a sky_sphere with some
pattern, or a large "world sphere" surrounding your scene.
Hide that background with a box placed behind your object.
Try using more light_source, make them coloured. Change ther positions to get
the best effect.
