Since 1900 and four generations in Salon-de-Provence France, the Marius Fabre soap factory has been perpetuating the Marseille soap tradition. Today, very few soap manufacturers use cauldrons in their production and even fewer are capable of following the cooking process to its ultimate stages, which includes its actual tasting in order to verify its done to perfection. At Marius Fabre, these methods are still in full practice and soap-making has remained an art.
