Which risk increases when an amorphous solid undergoes devitrification from increased temperature?

💡 Explanation

Heating above the glass transition temperature causes nucleation and crystal growth, known as devitrification, which results in grain boundaries. Because grain boundaries accelerate diffusion, corrosion leading to crack propagation occurs, rather than improvements to optical transmission or toughness in solid glass.
