There's a section in the manual about this already, but since it's a little out of date and cannot be directly linked to, I've created a new page in the online manual about correctly modelling glass (and also a bit about rendering interior and exterior shots, using glass acceleration).
Please have a look and let me know what you think!
Physically correct modelling of glass
Re: Physically correct modelling of glass
Only thing to mention could be:
Since it is for beginners you should mention that a "Indigo glass material" is a specular material with IOR of 1.52 and transparency enabled. To fully bank on preset materials will keep the starting user inexperienced in Indigos material system...... The simplest way to correctly model a glass pane, is to take a thin box (e.g. a cube squashed in one dimension) and apply an Indigo glass material to it ...

Ahh, a good suggestion! Thanks, I'll drop a word about this
Re: Physically correct modelling of glass
Nice! It;s a good start.
However, glass is such a fascination material that just barely scratches the surface. Not even window glass is really always simple. How about window glazings for example etc.

Re: Physically correct modelling of glass
Ok, now I also become greedy
How about a line about advanced tabulated based glass like this one from galinette:

Also a few words on cauchy B (with example image) would be maybe nice...

You can also turn the normal of the edges and assigned a correct material with the correct medium.
