Archive lamp 4006 is the oldest form of 1932, and the most iconic with its unique shape.
The production techniques are the same ones used 80 years ago. All the molds for these lamps are made of wood turned by Hadeland Glassverk’s own carpenter-moldmaker, To prevent them from burning up during the glass-blowing process, the molds are soaked in water for many weeks before use, and they are moistened after every time a lamp is blown. Four glassblowers work on each lamp. After they are blown, the lamps need to cool down, a process that can take from four or five hours up to many days. Then they are ground down in two stages, and the edges are polished according to the designers’ sketches.
