¿De verdad el vidrio de las iglesias medievales es más grueso abajo porque fluyó durante siglos?

Is the glass in medieval churches really thicker at the bottom because it "flowed" over centuries? You've probably heard it before: glass is a very viscous liquid that imperceptibly seeps out over time. But it's a myth! In this video, we debunk this popular belief and reveal the true and fascinating science behind the windows of historic cathedrals. ⛪✨ Although glass is chemically an amorphous solid, meaning its atoms are disordered, it's completely rigid at room temperature. It doesn't flow like honey or melt in slow motion. For gravity to deform a window in that way, it would take more years than the entire universe has existed. 🧪😲 The real explanation lies in medieval technology and craftsmanship. Back then, it was impossible to create sheets of uniform thickness. With methods like crown blowing, the glass pieces always had ripples and areas of varying thickness. Medieval glassmakers, who were incredibly wise and practical, placed the heaviest and thickest part at the base to give the stained glass windows stability and make them more resistant to wind. 🛠️ basket The ultimate proof of this is that, if you look closely, some windows have the thick side at the top or sides! If it were a gravity flow, all the pieces would look the same. The glass in those churches didn't melt slowly; it was born imperfect, and that imperfection is a testament to the incredible skill of the artisans of the past. 📜🎨 Did you know this scientific myth?
