The company's production plant is a popular tourist attraction. The company was founded by Johan Jeremiassen in 1885 and has produced designs by Norwegian artists such as Ferdinand Finne, Theodor Kittelsen, Frans Widerberg and Odd Nerdrum.
Since 1996 the factory has been owned by the Atle Brynestad company CG Holding AS. In contrast to its prosperous history, Porsgrund has since experienced a financial decline. After years of uncertain future, adjustments have been made to increase cost efficiency, by considerable restructuring to the production and sales processes.
