Indeed, it is rgbf <0.98, 0.98, 0.98, 0.9>, or a 90% filtered non-white.

But that isn't the whole problem, I believe, since the surfaces of those two
boxes are on the same plane.  You'll need to move the glass back in toward
the mirror a slight bit.  To explain: your mirror box and glass box both
start at <0,0,0> then you translated the glass -0.005*z exactly where the
mirror box reaches.

You may put  filter 1  into the texture like so:
 texture {T_Glass3 pigment {rgbf 1}}
That will override the previous color and filter setting but leave the
finish as is.

reflection is additive so be aware of that too.
