I’m at Risky Regencies today talking about Regency shop windows, shoplifting techniques, etc!
Windows with lots of small panes were popular in Regency storefronts for at least two reasons:
1. Glass was still taxed by weight. A larger pane requires a thicker weight of glass. (This applied to greenhouses as well, by the way. You see them with lots of little panes.)
2. Shoplifting and property crime was endemic, and a small pane of glass was easier and cheaper to replace if someone broke it to steal your goods.
