Yes, hot glass looks the same as cold glass.
why does hot glass look the same as cold glass?
Hot glass and cold glass may appear to look the same due to the fact that the surface of the glass remains smooth and glossy regardless of its temperature. This is because glass is a solid material and, unlike many liquids, does not undergo significant changes in volume when heated or cooled. Therefore, the shape and surface of the glass remain constant even as its temperature changes.
However, if you look closely, you may be able to notice some subtle differences between hot and cold glass. When glass is heated, it can emit a faint glow, particularly in low light conditions. Additionally, hot glass may be more flexible and may appear slightly distorted when viewed through it due to the bending of light as it passes through the material.
Furthermore, if you touch hot glass, you will immediately feel that it is much warmer than cold glass, and it may even burn you if it is hot enough. This difference in temperature can also cause hot glass to appear slightly blurred or distorted when viewed through it, particularly if there is a significant difference in temperature between the glass and the surrounding air.
