The Furnace

der ofen

In glassmakers slang, our glass-melting furnace is known as a tank furnace. In spite of coming with a high price tag (something like 3 million Swiss franks), the service life or «furnace campaign», as it is called, only extends to between 5 and 7 years. After the furnace has burnt itself out, it will be completely rebuilt from scratch by professional furnace builders, an operation lasting around 2 months.
