Getting pretty dizzy
This has to be one of the strangest windows we’ve ever seen. Did someone intentionally put vortexes in the middle of these window panes, or was this a manufacturing error? We’re getting pretty dizzy just looking at them.
A window expert on Reddit claimed that these windows were made a long, long time ago. At the time, the window-making process involved spinning molten glass at high speeds to get them to an even thickness, thus resulting in these swirl marks with slight bumps. Modern glass-making practices have made the spinning technique obsolete. Don’t think about removing those window panes and selling them. They’re not worth a darn.
