There is no recipe for any type of window, nor for the Hyperglass block. You can get Hyperglass for free if you play in "creative" mode.

In "survival" mode you have to use the Brown Mob's "alchemy" ability by trapping a Brown mob in the pit, surrounding it with a lot of Boron Crystal blocks and then shooting it. That's not a fruitful effort, because you lose most of your Boron crystal and it's just as transparent as Hyperglass anyway. But if you really want to have Hyperglass, see User_blog:Scooter8pie/Alchemy_and_the_Brown_Mob for more details.

Also, the transparent blocks don't work as windows for seeing enemies, see Materials.
