Around World War I (1914-1918), the main industrial pipe factory was Fratelli Rossi in Molina of Barasso (Varese), founder of a local art that would then refine and develop in several small, local industries that made and make the north-west site of Varese be identified as the pipe district.
Fratelli Rossi Company used to buy ebonite mouthpieces in St. Claude, a small French town in the Jura district. Seeing the great spread of the Italian competitor on many foreign markets, the French pipe makers pressed their local supplier to stop shipments of mouthpieces to Fratelli Rossi.

While the Italian factory was in a great development, — ever since 1920, it was considered the biggest pipe factory in Europe — the supplies of ebonite mouthpieces from France decreased day by day to compell Fratelli Rossi to contact and persuade the most prestigious rubber factories, like Azienda Pirelli, to take into consideration their request of producing ebonite mouthpieces.

Unfortunately, any Company was able to satisfy their demand. So, after numerous attempts, experiments and nights spent to find a solution to this problem, for the first time in Italy there started the production of ebonite mouthpieces for pipes at the factory in Molina of Barasso: it was 1922.

Carlo Giudici was one of the few people that worked with great will for a result that turned to be as much concrete as it could be ever be thought: he can be considered a Pioneer of ebonite mouthpieces in Italy.
