When a ray of light hits a trasparent object, one part of the energy is reflected, other part is refracted and a third is absorbed. You have three color parameters and LuxRender only has two, kr and kt, so it never can be physically correct.
Don't cry loud until you are really sure ...
Your missed parameter for refraction is called "index" (Index Of Refraction). And there are 3 more parameters. "couchyb" and 2 for a "film" - effect.
