When going on a leisure trip, I don't often consider touring industrial factories. Then again, I don't know if most people would consider North Korea a leisure trip. Still, being able to tour a glass factory as part of a vacation is definitely quite unique compared to the usual tourist circuit. Somehow, it just fits right in and works when it comes to North Korea.
Touring the factory I saw everything from glass melting furnaces to panes of glass rolling through the factory like here. There were quality checks along the way to automatically destroy bad panes, as well as some guys sitting at computers monitoring...whatever they monitor.
Having seen photos of a number of abandoned Soviet factories and buildings, I can only imagine what will happen to this place 10, or 20 years from now. Will it still be making glass, or will it one day be mothballed?
