You won't see a difference between using an RGB color vs a greyscale color. For glass you normally use an IOR around 1.5, and both reflection and transmission set to 1.0. You have to make sure normals are pointing in the correct direction.

Ok but I set reflection 0.5. :) Normal map?
But ~64k-sample is good for almost true glasses. :)
