Okay kiddo, let's talk about forest glass!
You know how we use glass to make things like windows and cups? Well, forest glass is a type of glass that was made a long time ago in Germany's Black Forest. It's called "forest glass" because it was made in the forest using wood and other natural materials.
The people who made forest glass would gather wood from the forest and burn it in special ovens. They would then add sand and other materials to the hot oven to create a special kind of glass. This glass was used for things like glasses, vases, and even windows for buildings.
But, making forest glass wasn't easy. It took a lot of skill and hard work to make it just right. The people who made forest glass were called glassblowers, and they were very talented. They could shape the hot glass into different objects using special tools.
Nowadays, forest glass isn't made anymore because we have new ways of making glass that are easier and faster. But, some people still collect forest glass as a reminder of the old days and the people who used to make it.
So, that's forest glass in a nutshell! It's a special kind of glass that was made a long time ago in the forest using wood and other natural materials. People who made it were called glassblowers, and they were very talented at shaping the hot glass.
