That’s not true, those old windows have always been deformed in that way because people back then weren’t good at making glass, but their shake hasn’t changed.
Correct, but it’s but because they were bad at making glass, it’s that making glass is hard, and a sturdier bottom is less likely to break. They were very good at making it, they just didn’t have high precision manufacturing.
And they are usually thicker at the bottom because people were smart enough to realize there’s less risk of breakage if the weight doesn’t rest on the thinner end.
But there are some cases were the thicker part is up.
