True
Glass is an amorphous solid that remains solid at normal temperatures and only softens above 600°C. Old windows are thicker at the bottom due to manufacturing methods, not because glass flows.
Infact verdict: True (93/100).
The claims about glass being an amorphous solid, its softening point, and the reason for old windows being thicker at the bottom are well-supported by scientific and historical evidence. Glass is indeed an amorphous solid with randomly arranged atoms, and it softens gradually rather than having a fixed melting point. The thicker bottoms of old windows are due to historical manufacturing techniques, not because glass flows over time.

Science
Glass stays solid at all normal temperatures and only softens above 600°C (1112°F).
Evidence from multiple sources indicates that glass remains solid until it reaches about 600°C, where it begins to soften. This is consistent with the known properties of glass.

History
Old windows are thicker at the bottom because of how they were made, not because glass moves.
The claim is supported by historical evidence showing that old windows are thicker at the bottom due to manufacturing techniques, not because glass flows over time. This is a well-documented fact.
