For the emisive material, change the 100% (R0/G0/B0) black surface for something little more lighter, you will see the glow efect. For the glass, it's a reflective material, you made a single plane pointing the sky, its reflecting the blue of the sky, the material is correct. Try ussing it on a more complex shape, like a vase or something, and inside a enviroment with something that the glass can reflect. You will see a diferent result. Sorry for the bad english.
