Nils Thorsson's name came to prominence when he exhibited a series of variegated faience (autumn series) in 1925, which won a gold medal at the World Exhibition in Paris. Around 1930 he began to modernize the potting and spraying technique, thus paving the way for a rationalization of the production of etel; in 1937, in collaboration with the technicians, he produced the 'industrialized Stel', which meets both technical and aesthetic requirements. With a number of different, good decorations ("Sonja", "Sun Bride", "Jenny" and others).

In 1939 he drew a new undecorated set: 'Alma'. In addition to the dinner services, T. designed models and decorations for vases and bowls in earthenware (Solbjerg, Bremerholm, Lustrefajance, Tenera and Baca), matt porcelain and stoneware (Jungle and works in Solfatara, Clair de lune, Olivin, Dilou etc.) T.'s relentless desire to experiment with new glazes and ceramic fabric effects has produced remarkable results; he knew how to turn a pot and had a fine sense of form and decoration. His subject matter was vast, ranging from pure naturalism to abstract, geometric patterns, executed either painted or in relief. In his confident, light brush technique, ancient ceramic tradition and culture can be traced - Works in the Museum of Decorative Arts in Copenhagen, The Royal Porcelain Factory Museum, Copenhagen.
