Glass disease
Glass disease is a condition that happens to old glass. Just like how we get hurt or get sick when we get old, glass can also get sick too. When glass is really old, it can start to change its shape and look wavy or bumpy. This can happen because the glass is reacting to things like heat or humidity in the air. And just like how our skin can get wrinkles when we get older, glass can also start to look like it has wrinkles or cracks.
Some people like how glass looks when it has these changes, but others don't like it because it makes the glass look not very pretty or valuable anymore. That's why it's called a "disease," because it can make the glass look sick. But it's important to remember that glass disease doesn't actually make the glass unhealthy or harmful, it's just changing how it looks.
