Orrefors purchased Flygsfors and the factory continued to produce glass
lamp designs for a limited period using their designers.
They then closed the factory which was shut down until the 1990's when the factory shell was purchased by an individual.
They then reopened the factory with a glass studio orientation. Behind the
old factory were piles of scrap glass with every color imaginable. The new
owner used these scrap colors as his glass mass and started to produce
simple, designs with the swirls of color. He defined a separate name for this glass which I have forgotten.
His goal was to make the site a tourist site but seems to lack the capital.
Your piece is not a fake but from this new operation at the Flygfors
glass works. The name is still on the side of the building.
