I'm not sure what to even use as a search term for this one!

Why is it that back faces render black in some materials even when they have normal light on them? 
Is there a way of avoiding this by doing something specific in the material room?

I think I even saw something about being able to have front of faces different then back faces, but I can't seem to find that thread again. I believe it was by bagginsbill.
Help, pleeez... anything to point me in the right direction would be wonderful.
