Hi,
Translucent glass comes as structured clear glass, edged, screen 
printed, sandblasted etc. and its forward scattering varies considerably.
Or are you looking for coated glass, which is non-diffuse, but its 
directional transmittance ("transmission"- whatever, with or without 
Fresnel) varies form the rule-of-thumb 10%-reflexion-at-normal-incidence 
too ?
