For now we see through a glass, wavily.
According to some observers, wavy old glass has artistic value and I have to say that I also think it’s kind of cool. I had heard that old glass is wavy because it flows over time, bunching up at the bottom of the pane, but that’s not true. Instead, the waves are the result of the original production process.
These photos are of window glass in Hampton Plantation House, built in stages from 1735 to 1790. Are these panes of glass original to the house? Dunno. But they’re not new.
