In 1936, Aino and Alvar Aalto were commissioned to design the interior of the Savoy Restaurant in Helsinki. Modern interior designs were drawn up in the drawing office at Artek, which had just been set up. The designs, with their new furniture and light fittings, were published in the press and were very well received. Kultakello, a graceful, brass light fitting, was created while the lamps were being designed. It was also on show at the Paris World Exhibition in 1937.
In the early 1950s, Artek created a range of lamps that were available over the counter and were within the reach of all their customers. A newer version of A 330, Kultakello, was produced for this range. The closed, bell-shaped, cast-metal lamp without openings was then made in three parts: the cover, the shade and the perforated ring that was bent to reflect the light. Thus the lamp, which previously had been closed, was given a more interesting appearance and the redesign prevented the lamp from overheating.
