plate glass

At the lower or west end of the room the wall had been removed and replaced by a single immense pane of plate glass.

Even the shops that were closed offered, through wide expanses of plate-glass, hints of hidden riches.

I have taken care to keep them under lock and key, behind plate glass, for more than fifty years.

Yes, there they sit; and others, perhaps, besides Fitz have cast a sheep's-eye through those enormous plate-glass windowpanes.

That stuff must be a hundred times more transparent than the finest plate glass!
