Arnoux had an interest in reviving Saint-Porchaire ware, then generally known as "Henri II ware". This was very high-quality lead-glazed earthenware made from the 1520s to the 1540s in France; in 1898 the pottery was located to the village of Saint-Porchaire (nowadays a part of Bressuire, Poitou). Perhaps sixty original pieces survive, and at the time the ware had a legendary repution. This was a very complicated ware to make, with much use of inlays of clay with different colours. Arnoux mastered the technique and then taught Charles Toft, perhaps Mintons' top modeller, who produced a small number of pieces. In addition to his influence on the production of encaustic tiles and mosaics, Arnoux also developed and produced azulejos in the Portuguese style.
