    I had a teacher in high school tell us that glass is an incredibly slow moving liquid, and that’s why on really old buildings the glass is thicker at the bottom, because it has flowed and “pooled” like that.

    I believed that for a good number of years and even repeated it a few times before finding out that no, it’s not, and the reason some old glass is like that is simply because of the manufacturing process at the time, and that it was simply installed thick side down for aesthetic reasons, and that you can actually find old glass that is thicker at the side or top because it was installed differently.
