Old window panes look wavy, distorted, and handmade - even after 1900. Understand their manufacture, and you'll know why.
Ever peer through an old window and see ... the glass? The distortions in antique glass are part of the charm of old windows and a historic feature well worth retaining. Though some may tell you that ripples and dimples are a sign of age - as if glass sags like flesh after a century - the truth is less fantastic, though almost as amazing.
It's all a result of how glass was made. Once you grasp the two basic methods used to make window glass until the 1910s, you can tell a lot about the age of your windows and how to care for them.
