As a leading industrialist, Wedgwood was a major backer of the Trent and Mersey Canal dug between the River Trent and River Mersey, during which time he became friends with Erasmus Darwin. Later that decade, his burgeoning business caused him to move from the smaller Ivy Works to the newly built Etruria Works, which would run for 180 years. The factory was named after the Etruria district of Italy, where black porcelain dating to Etruscan times was being excavated. Wedgwood found this porcelain inspiring, and his first major commercial success was its duplication with what he called "Black Basalt". He combined experiments in his art and in the technique of mass production with an interest in improved roads, canals, schools and living conditions. At Etruria, he even built a village for his workers. The motto, "Sic fortis Etruria crevit," was inscribed over the main entrance to the works.
