Glass that promises clarity and delivers mostly your own reflection at night.

means A single pane of glass set into a window frame, dividing the sash into its gridded sections.

from A straightforward compound: 'window' (from Old Norse 'vindauga,' literally 'wind-eye' — the hole early homes left open for light and air, long before glass arrived) plus 'pane,' from Old French 'pan,' meaning a piece or section of cloth or surface. So a windowpane is literally a 'section of the wind-eye' — the small fitted piece that finally let people glaze over that old open hole and keep the wind out while the light stayed in.
