A closer look

Glass is technically an amorphous solid, completely shattering the widespread urban legend that it is a highly viscous liquid that slowly flows downwards over centuries. The thicker bottoms of antique stained-glass windows are simply the result of historical manufacturing techniques where glassblowers spun molten glass into discs and placed the heavier edges at the base for stability. Physics officially confirms that glass molecules are locked firmly in place, meaning those ancient church windows are not melting, they were just made by people who lacked standardized quality control. It is hilarious how an entire generation of science teachers confidently lied to us just to explain away shoddy medieval craftsmanship. Your window panes are absolutely solid and stationary, fiercely holding their ground against the relentless pull of gravity!
