Can microwaves either change the eV of electrons, or move...

Main Question or Discussion Point

-the electrons to the same shell levels of glass as the microwaves pass through and heat the material, or move electrons in a opaque material to the same energy levels, or shell levels of glass, and transparent liquids, and some plastics.
In a microwave the waves traverse food, and heat the food up, so I am thinking microwaves traverse solid material, while heating the material up.
But can the same principle be used to move electrons to higher shell levels, but the exact shell level that is in glass material.
Atoms coming together to make a covalent bond changes the eV requirements of electrons to visible light, as when silicon, sodium, and calcium come together to form glass.
The electron energy levels in glass are fixed, for light to transmission through a solid material, but as electrons move to higher shell the levels the eV requirements CHANGE.
I am not 100% sure the the electrons can reside in shell levels 2, or , in a opaque material, and that they do not excite visible light though, even though the electrons are in these shell levels temporarily for milliseconds.
So because microwaves traverse, and heat material, BUT do not get absorbed by electron ( I think) this is a possible way to get electrons to higher shell levels.

I asked a question on a forum about if electrons could move to higher shell levels, and someone said "All sorts of energy can do it, but heat is probably the easiest. If you can get metal up to just over 2000°C it will emit visible light because the electrons are being temporarily boosted to higher shells. Best example of this is the tungsten filament in a light bulb - firing off photons in all directions."
I am grateful for your help, anything helps, even a few words. http://www.thenakedscientists.com/forum/Smileys/default/cheesy.gif [Broken]

The available energy levels are purely given by the molecular/crystal structure. You cannot change the existing energy level with microwaves (unless you melt/evaporate something with heat), you can just change the occupancy.

That does not make sense.

Absorption and getting electrons, atoms or molecules* to higher energy levels are the same thing in typical materials.

*microwave absorption in water does not change the energy level of electrons, it excites vibrations of whole water molecules.
