Are you curious when you look through the pane? Did you know that fire turns

dust into rain? How did this liquid become hard as a stone? A secret of

earth and we add a high heat to make a material that's sturdy

and neat. It's an amorphous solid, not quite a gas,

that's the magic of making a window of glass. When did it start?

Let's travel back far, to 3-500 BC under a star.
