Glass material properties and thermal shock

Why do glass dishes break on a hot stove?

When placed on a hot stove, why does an ordinary glass dish usually break?

Answer:

A glass dish breaks on a hot stove due to thermal shock, which occurs because glass doesn't uniformly distribute heat.

When an ordinary glass dish is placed on a hot stove, it is likely to break due to a phenomenon called thermal shock. Glass is a material that does not conduct heat well, which means that it does not distribute heat evenly across its surface. As a result, when one part of the glass dish is exposed to the heat of the stove, it expands more rapidly than the rest of the dish.

This uneven expansion creates stress within the material, leading to cracks or breaks in the glass. This is why it is important to use glassware that is specifically designed to withstand thermal shock in situations where it may be exposed to high temperatures.
