Trapped in a crystal? How do you even make a crystal like this

Very small rocks … with some kind of tiny furnace, bitty crucible, and naturally a wee glass blower.

"Trapping electrons in a crystal" is such a nonsensical way of conveying the idea of a flat band. Most isolated crystals trap all the electrons they have inside of them, or else the world will be full of free roaming electrons!
