Yes, very much so! About 300 years ago, glass producers came to the Harz. Here was the valuable fuel that they had already run out of elsewhere.
WOOD!
At the beginning of the 16th century there were lush forests in the Harz Mountains. The wood deposits were sufficient to drive glass production in the Harz region for over a century. The forest glass era came to an end around 1700. By law, the now scarce wood was allocated to mining. That was the end of the forest glass age in the Harz.

Of course, and in Steinatal you have particularly good chances. At forks in the road and along streams, you can find shards, kiln remains or slag residues in the ground. If that is the case, please let us know. However, removing these finds from the site is not permitted! If you find traces, you are legally obliged to report this discovery. We have provided you with a form here that must be sent to the lower monument protection authority.
