Until 2005 he worked at Orrefors glassworks, and has subsequently been a professor at Konstfack (University College of Arts, Crafts and Design) and an independent artist.
In his glasswork, Sundberg often uses inset images in the form of decals from the old Gustavsberg porcelain factory and with properties to withstand high temperatures.
[9] Per B. Sundberg grew up in Huddinge, south of Stockholm, where he early showed interest in creative expression, including in textile.
[12] After training at Konstfack, he and some fellow students established a glass studio on the islets Fjäderholmarna, at the inlet to Stockholm.
Here Sundberg blew glass, inter alia together with his colleagues Gunilla Kihlgren and Mårten Medbo.
His glass art also attracted international attention and purchases, including by the Victoria & Albert Museum in London.
The Litograal technique is similar, in which the decals are replaced with black and white copies from comic books, often of a sexual nature.
When operations ceased at the factory, a number of independent artists moved into the premises, including Sundberg.
An important element in Sundberg’s artistic process is to use materials that others have left: clays, glazes, decals and figurines.
