The Liquid Myth
Debunking the 'slow-flowing' glass theory through molecular reality.
- The Legend
The Sagging Window Myth
Many believe old cathedral windows are thicker at the bottom because the glass flowed downward over centuries. This is a scientific fallacy.
- Physical State
Amorphous Solids
Glass is not a slow-moving liquid. It is an amorphous solid, meaning its atoms are locked in a disordered, random state.
- Atomic Structure
The Crystal Contrast
Unlike diamonds or salt, glass lacks a repeating geometric lattice. Its molecules are frozen in a chaotic, liquid-like arrangement.
