Glassblowing
The Black Forest was once almost gone.
The glassblowing craft in the Black Forest is very old. Its beginnings probably date back to the twelfth century. Glass was produced along several river courses such as the Kinzig and the Murg. The first glassworks were established on the Feldberg around 1579, mainly due to the nature of the soil with its high content of quartz, a raw material indispensable for glass production.
Originally, glassworks were not tied to a fixed location. They were usually leased by a landowner to the master glassblowers. Since a lot of wood was needed for their work, the forest around a glassworks was quickly cleared and the workshop had to be moved to another location.
The exact knowledge for the production of the glass was kept secret by the master glassblowers. Moreover, it is rumored that the master glassblowers all came from a single widespread family that was only intermarried.
Since the glassworks of the Black Forest were very far from the actual place of use of the glass produced, it had to be transported there. This was done by glass carriers who brought the material on their backs with a large stretcher, the so-called "Krätze", to the towns where it was sold at markets.
Glassblowing then changed significantly in the eighteenth century. As the demand for glass increased enormously, especially for windows, larger factories sprang up in various places, around which entire villages were settled to accommodate and supply the needed labor.
Together with rafting and charcoal burning, glassblowing also led to the almost complete deforestation of the Black Forest. Incidentally, this was originally a mixed forest and not a coniferous one as it is today. The fact that there are many spruce trees today is primarily due to their rapid growth, which predestined them for reforestation.
Nevertheless, the industry of glass production has survived to the present day. Traditionally working glassblowing factories still exist today. You can watch the glassblowers at work in various places, such as Alpirsbach, Altglashütten near the Feldberg, Buhlbach near Baiersbronn or Herrischried. This is also possible in the Dorotheenhütte in Wolfach, where there is even a glass museum. In addition, many place names with the component "glass" remind of the long tradition in the Black Forest. There is often a "Glashalde" ("glass dump") or a "Glasbach" ("glass brook") and the Black Forest Railway even has three "Glasträgertunnel", which means "glass carrier tunnels".
